What kind of sequence or structure would you classify this as
jeka57 [31]

Answer:

The correct answer will be option-A.

Explanation:

Inverted repeats are the sequence of the nucleotide in a nucleic acid which is identical but arranged in the opposite orientation. The inverted repeat may be separated by some sequence or they may lie adjacent to each other. They can be read the same from the backwards or forward direction.

In the given question since four bases when read from the forward direction is same as reading the sequence from the backward direction like CGAC can be read the same both backward and forward.

Thus, option-A is the correct answer.

What is the main difference between bacteria and humans that gives Sulfa drugs their antibacterial properties? Group of answer c
sertanlavr [38]

Answer:

Human cells can readily absorb folic acid; bacteria cells cannot.

Explanation:

Bacterial cells cannot absorb folic acid and synthesize it. On the other hand, humans do not synthesize folic acid in their cells. They rather obtain it from the diet. Sulfa drugs, for example, sulfanilamide resemble p-aminobenzoate (PABA). PABA is a molecule that is used as a substrate in the synthesis of the coenzyme folic acid. The sulfa drugs serve as competitive inhibitors and compete with PABA for the catalytic site of an enzyme involved in the folic acid synthesis. This prevents the synthesis of folic acid in bacterial cells and thereby, inhibits bacterial growth.
