The correct answer is option D, there is no gene flow

Reason-

As the genes flow between the two species, the genotype and phenotype variations between the two species reduces. This is so because the genetic variation between the two species narrows down with exchange of genetic material or allele. Thus, the higher two different individuals do not mate together the more or high will be the expression of a specific allele in a gene.

Energy conservation in thioesters, acetyl-CoA and succinyl-CoA:

enot [183]

Answer:

B. ensure the production of GTP in the case of succinyl-CoA

Explanation:

Succinyl CoA like acetyl-CoA has a thioester bond with very negative free energy of hydrolysis. In this reaction, hydrolysis of the thioester bond leads to the formation of phosphoester bond with inorganic phosphate. This phosphate is transferred to histidine residue of the enzyme and this high energy unstable phosphate is finall transferred to GDP resulting in generation of GTP.

Hence the answer is B. ensure the production of GTP in the case of succinyl-CoA.

Supply the appropriate labels for all numbered parts of the illustration.

tatiyna

Answer:

This diagram depicts the phenomenon of DNA translation in the central dogma of life. Here are the labels

1. RNA strand because it is a sequence of four nucleotide A, G, C, U. It has Uracil, this is why it is RNA. Further, translation takes place when DNA is already transcribed.

2. Ribosome is a machinary for protein formation. This is because it provides right environment to transfer RNA to decode RNA strand into a protein sequence.

3. Amino acid: Each amino acid is carried by a transfer RNA (tRNA). The type of amino acid depends on type of tRNA. All proteins are mostly formed with 20 amino acids and so there are at least 20 tRNA.

4. Polypeptide (protein) chain made up of amino acids: It depicts multiple amino acids, which tRNA carries, and are bonded together through peptide bonds.

5. Transfer RNA (tRNA): tRNA has a complementary sequence to RNA strand and thus it binds with right sequence. It carry an amino acid which is then bonded to another amino acid amino acid to make a polypeptide chain.
