How are genetic relationships represented?

vichka [17]

Answer:

Genetic relationships are analysed based on the comparison of allelic identity or differences, regardless of the number of SNPs that differ between two alleles of a gene, which simplifies the analysis.

You are attempting to synthesize rRNA in a test tube using DNA isolated from mouse cells. In addition to the template DNA, ribon

olga55 [171]

Answer:

d. RNA polymerase II.

Explanation:

The main enzyme responsible for RNA synthesis is RNA polymerase, which catalyzes the polymerization of 5'-triphosphate ribonucleosides (NTP) directed by a DNA mold.

Eukaryotic cells contain three types of nuclear RNA polymerases that transcribe different types of genes. Protein-encoding genes are transcribed by RNA polymerase II to give mRNA.

Cytopathic effects are changes in host cells due to.

anzhelika [568]

Answer: viral invasion.

Explanation:Cytopathic effect or cytopathogenic effect (abbreviated CPE) refers to structural changes in host cells that are caused by viral invasion. The infecting virus causes lysis of the host cell or when the cell dies without lysis due to an inability to replicate. Both of these effects occur due to CPEs.

Under anaerobic conditions, such as intense exercise, pyruvate is converted to ____________ . This 3-carbon molecule travels thr

stiv31 [10]

Answer:

Under anaerobic conditions, such as intense exercise, pyruvate is converted to lactate. This 3-carbon molecule travels through the blood to the liver, where it can be converted to glucose by the cori cycle.

Under aerobic conditions, pyruvate enters the mitochondrion, where it is converted to acetyle CoA . This 2-carbon molecule goes on to participate in a series of oxidative reactions called the Citric acid cycle.

Explanation:

In the question ,among the given 6 options ,the simplest way to find the answer can be ,to find either the option is aerobic (presence of free oxygen ) or anaerobic (lack of free oxygen). Among the options , glucose is an incorrect option as it is a carbohydrate and used in respiration process .In aerobic process ,the glucose can be break down but in anaerobic ,it can only be used.

Other option is ATP- ATP is the energy source of the cell and used for storing energy or reactions of the cell,thus this option do not belong to the given question.

thus its clear the rest four options are the answer .

among four two options belong to aerobic and the rest two are anaerobic.

Under anaerobic conditions-

The pyruvate is converted into lactate because under the absence of oxygen only the NAD+ can be regenerated, thus further can allow glycolysis.

The cori cycle is also called lactic acidic cycle, thus this cycle is a metabollic pathway produced by anaerobic glycolysis (which takes place by regeneration of NAD+)transporting the molecules from blood to liver and further converting to glucose

Under aerobic conditions,-

The pyruvate is converted into Acetyle CoA so as to further produce citric acid and then citric acidic cycle. Thus Acetyle CoA forms more ATP which help in the regeneration of NAD+ and production of citric acid cycle takes place.

HENCE , The correct options are - lactate cori acetyle CoA citric acid.
