Various strains of bacteria are able to transfer genes to eukaryotic hosts. This process of horizontal gene transfer often results in the formation of enzymes in the host organism that assist in metabolic pathways. What is the most likely explanation for why bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells?
Answer:
Due to conjugation.
Explanation:
Bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells because of conjugation process. Conjugation is a process by which one bacterium transfers its genetic material or genes to another bacterium or cell through direct contact with it. During conjugation, the bacterial cells serves as the donor of the genetic material, and the eukaryotic cell serves as the recipient that receives the genes.

g In transcription, the 3'-hydroxyl group of the growing RNA strand: Group of answer choices NONE OF THESE binds to the 5' ribose. attacks the outermost phosphorous group of the incoming nucleotide. ALL OF THESE attacks the 5' hydrogen of the incoming nucleotide. interacts with a positively charged metal ion in the active site.
Answer:
attacks the outermost phosphorous group of the incoming nucleotide.
Explanation:
Transcription is the biological process where RNA is formed. As you may already know, RNA is an extremely important nucleic acid for genetic processes and the production of proteins. The transcription has three steps that are called start, elongation and end. In the elongation phase, the RNA strand is growing, at this time, RNA polymerase, which is the enzyme responsible for RNA elaboration, places the nucleotides, in the RNA strand, in the 5' - 3' direction. This enzyme causes the hydroxyl, which makes up the nucleotide at the 3' end of the forming RNA, to attack the phosphorus present in the incoming ribonucleotide.
An enzyme that breaks DNA, dispels the tension, and reseals the strand ahead of a DNA replication growing fork is called a(n):
Answer:
Topoisomerase
Explanation:
Topoisomerases are enzymes that produce changes in the topology of the DNA during replication, transcription, traduction, or reparation processes. They can cut one or both strands and in order to relieve torsional stresses in the supercoiled structure of DNA. With this, they help to maintain the chromosome's integrity. There are two types of topoisomerases: topoisomerase I (it cuts only one strand of DNA) and topoisomerase II (it is able to cut both strands of DNA).
he conversion process where nitrogen gas combines with hydrogen to form ammonium ions, which is accomplished through the intense energy of lightening, or when air in the top layer of soil comes into contact with certain bacteria, is known as
Answer: The conversation process where nitrogen gas combines with hydrogen to form ammonium ions is known as THE ACTION OF THUNDERSTORMS while when air in the top layer of soil comes into contact with certain bacteria, nitrogen in the air is converted by NITROGEN- FIXING MICROORGANISMS.
Explanation:
About 79% of air is composed of gaseous nitrogen. However, only a few microorganism can make use of this nitrogen. The important sources of nitrogen for plants and most living organisms are the inorganic nitrogenous compounds in soil. In nature, nitrogen is constantly being removed from the soil and returned to it through the NITROGEN CYCLE
Conversation of gaseous Nitrogen into nitrogenous substances such as ammonium and amino-compouds are carried out by:
--> The action of thunderstorms, and
--> NITROGEN- fixing microorganisms.
During thunderstorms, Nitrogen reacts with oxygen to form nitric oxide. The nitric oxide is oxidizes to Nitrogen peroxide which dissolves in rainwater to form nitric and nitrous acid. When these acids enter the soil, they combine with mineral salts to form nitrates. The nitrates then, dissolve in soil water and are absorbed by the plants. These nitrates are converted into plant proteins and become part of the plant body.
Some microorganisms such as the Nitrogen fixing microorganisms are able to absorb nitrogen from the atmosphere and change it into amino-compouds and proteins. Examples of such microorganisms include:
--> the free living bacteria: these include the azotobacter and clostridium
--> the symbiotic bacteria: the rhizobium which is found in the root nodules of leguminous plants
Scientists have discovered a new marine bacterial species called Vibrio nuigii. They have isolated ten strains of this bacterium and determined their whole genome sequences. Only one of the strains (which the scientists named Vir1) is virulent and causes disease in oysters. Describe three ways in which the scientists could use their knowledge of the bacterial genome sequences to identify the genes responsible for virulence.
Answer:
1-by transfecting small interfering RNAs against target genes of interest
2-by using comparative genomics strategies in order to infer functional relationships among target genes of interest and homologous genes responsible for virulence in other bacteria (e.g., antibiotic resistance genes)
3- by inducing mutations through site-directed mutagenesis in order to study gene function (i.e., by examining the effects of knockout mutations)
Explanation:
Whole-genome sequencing (WGS), also known as complete genome sequencing, refers to Next Generation Sequencing technologies that allow the obtention of the entire genetic sequence of an organism/cell, which can be used as a reference genome to understand gene function, evolutionary relationships, etc. The information provided by WGS technologies allows making many different types of genetic analyses in order to understand gene function. First, the nucleotide reference sequence can be used to design complementary small interfering RNAs that trigger degradation of target messenger RNAs (mRNAs) by the RNA interference (RNAi) pathway, thereby inhibiting gene function (in this case, inhibiting genes associated with virulence in the bacterial strain). Second, a reference genome is required to perform bioinformatic data analyses in order to identify homologous genes associated with virulence in evolutionarily related bacteria, allowing identify, for example, antibiotic resistance genes or sequence polymorphisms (e.g., single nucleotide polymorphisms, SNPs) associated with gene function. Third, the information provided by a reference genome can also be used to trigger site-directed mutagenesis (for example, by using the highly precise CRISPR-Cas9 genome editing technology) in order to knock out specific genes of interest and thus analyze if the bacterial strain is still infectious.
When O2 binds to heme in hemoglobin, the ion is drawn into the plane of the porphyrin causing a conformational change that is transmitted to adjacent subunits enhancing the for additional O2 binding. Group of answer choices Fe2 ; affinity Mg2 ; folding Mg2 ; planarity Fe3 ; affinity
Answer: Fe2 ; affinity
Explanation:
Hemoglobin is the specialised protein which are present in red blood cells which gives it the ability to carry oxygen to the tissues and return carbondioxide from the tissues to the lungs.
The hemoglobin is made up of
--> a heme group: this consists of a ferrous iron ( Fe2) and a surrounding porphyrin ring.
--> globin.
As the haemoglobin molecule loads and unloads oxygen (O2) the individual globin chains in the hemoglobin molecule move on each other. When oxygen is unloaded the beta chains are pulled apart, permitting entry of the metabolite 2,3-diphosphoglycerate resulting in a lower affinity of the molecule for oxygen and higher affinity for carbondioxide.
Also, when the partial pressure of oxygen (PO2) in the blood is high, the beta chains move close together, O2 binds to heme in hemoglobin, the ion Fe2 is drawn into the plane of the porphyrin causing a conformational change that is transmitted to adjacent subunits enhancing the AFFINITY for additional O2 binding.

Hyperglycemia (elevated blood sugar levels), such as would happen in diabetics, can damage the glomeruli.
a. True
b. False
Answer:
True
Explanation:
Hyperglycemia which means high Glucose level in the blood as a result of lack of insulin can damage the glomeruli. This interfere with the function of the glomeruli. Normally glomeruli fiters blood and remove nutrients to form urine but hyperglycemia will affect it's negatively and will make protein to leak from the blood into the urine. This can also lead to glomeruli called glomerulosclerosis.

How would that change affect the molecule
Answer and explanation:
Sickle cell anemia is a type of anemia that occurs because of a mutation in the HBB gene, which codifies for the beta subunit of hemoglobin, producing an abnormal beta-globin called Hemoglobin S o HbS. This anomalous beta subunit is a product of the replacement of the amino acid glutamic acid by the amino acid valine at position 6, resulting in a beta-globin that forms a long and rigid molecule turning red blood cells shape into a sickle one, condemning erythrocytes to a premature death (which will cause the anemia). Another complication patients with sickle cell anemia can have is the blocking of blood vessels because of the abnormal and rigid shape of their red blood cells.
