quzilet Which of the following occurs when DNA is replicated? Group of answer choices One strand of the parent DNA is preserved;
Bad White [126]

Answer:

The two strands of the parent DNA are separated, and two daughter DNA strands are formed.

Explanation:

DNA replication is a complex process which replicates or produces new DNA molecule from the parent DNA molecule mediated by enzymes and ATP.

The mechanism of DNA replication is known as the semi-conservative mode in which one new strand of DNA is synthesized complementary to the one strand of DNA. To form a new DNA molecule both the strand of the DNA gets separated and then a new daughter strand is formed complementary to each parent strand.

Thus, the selected option is correct.

These are nucleotides that have a single ring structure. Example: Cytosine, Thymine, and Uracil
IgorLugansk [536]

Answer:

The question is incomplete.

However, I notice that your question is mainly dealing with

"Nucleotides with a single ring structure"

I tackled that part, also providing explanation to the point you focused on.

Explanation:

Nucleotides are compounds in which nitrogenous bases (purines and pyrimidines) are conjugated to the pentose sugars (ribose or deoxyribose) and at least one phosphate group. Thus a nucleotide consists of a nitrogenous base, pentose sugar and at least one phosphate group.

Examples of the nitrogenous bases are Adenine, Guanine, Thymine, Uracil and Cytosine. Of all, Thymine, Uracil and Cytosine are with single ring, while Adenine and Guanine are double ring structure.
