Deletion of a DNA base from a gene affects an organism by—

Biology

8 0

Answer:

Deletion of a DNA base from a gene affects an organism by changing the sequence of amino acids in a protein.

Explanation:

A DNA fragment forms a gene, with a specific sequence of nitrogenous bases, which determines the synthesis of a specific protein. When a deletion of a base occurs in such a gene, it affects:

  • Transcription of the mRNA, which will have the sequence of altered bases.
  • During translation, the mRNA codons will encode at least one different amino acid.
  • The structure of the synthesized protein, which will be altered by changes in its amino acid sequence.

In summary, the <u>deletion of a base in the DNA</u><u> will affect the </u><u>protein</u><u> to be synthesized by </u><u>changing the amino acid sequence</u><u> of its structure</u>.

The other options are not possible, because the deletion of a base in the DNA of a gene

<em>     Does not influence the number of chromosomes that the gametes will have. </em>

<em>     It does not produce long chains in the chromosomes. </em>

<em>     It does not affect the ribose structure of the nucleic acids.</em>

Explain why serine proteases do not catalyze hydrolysis if the amino acid at the hydrolysis site is a D-amino acid. Trypsin, for
kotykmax [81]

Answer:

Explanation:

A protease is an enzyme that catalyzes the hydrolysis of the peptide bonds that tie polypeptide chains together, releasing individual amino acid subunits. The L and D nomenclature for amino acids defines the structure of the glyceraldehyde isomer through which the amino acid can be produced.

SEE BELOW FOR THE APPROPRIATE STRUCTURES.

We need to figure out why swine proteases hydrolyze L-amino acids but not D-amino acids in any way. we know that enzymatic catalysts act as polypeptides if you can recall. They must retain a very precise three-dimensional structure for a catalytic activity to occur. Substrates that do not quite match the required configuration at the active site will not be reacted to — this is a "lock and key" style.

The present exercise may be explained by the fact that the configuration and structure of D-amino acids prevent them from binding properly to the active site of the protease enzyme. Perhaps they're pointed in the wrong direction, or perhaps there happens to be missing electrical interaction that's needed to keep the substrate in position.

Nonetheless, L-amino acids, on the other hand, seem to have the right configurational aspects in the active site and are hydrolyzed.

Is facilitated diffusion passive or active
kirill115 [55]

Answer:

Damian here!(ノ◕ヮ◕)ノ*:・゚✧

Explanation:

Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.

so its basically passive

Hope this helps? :))

A biologist analyzes the DNA sequences of one gene in three different primates . The biologist finds that primates A and B have
Nataly_w [17]

The question is incomplete as it does not have the option which are:

  • primates A and B are more closely related to each other than either is to primate C.
  • all three primates appeared on Earth at about the same time.
  • either primate A or primate B must be a direct ancestor of primate C.
  • primate C must have been the ancestor of both primate A and primate B.

Answer:

Primates A and B are more closely related to each other than either is to primate C.

Explanation:

In the given question, on the basis of the given information, it can be predicted that the Primate A and B are more closely related to C as the DNA sequences of these two primates are almost similar. The similarity of the sequence suggests that these primates have descended or diverged from a common ancestor.

The DNA sequence of C is different from both A and B which shows that both A and B are different from the C.

Thus, the selected option is the correct answer.

Each replicated chromosome pairs with its corresponding homologous chromosome. True or false
natta225 [31]

Answer:

True

Explanation:

Each replicated chromosome pairs with its corresponding homologous chromosome forming a tetrad. During tetrad formation, alleles can be exchanged between chromatids, a process called crossing-over.
