During S phase stage of interphase the cells copy their chromosomes.

Explanation:

The S phase of a phone cycle happens during interphase, before mitosis or meiosis, and is liable for the amalgamation or replication of DNA. The cell makes an indistinguishable duplicate of every one of its chromosomes. Chromosomes are found inside the core of the cell and comprise of long strands of DNA that contain the hereditary data of the cell.

G2 stage: This happens after the DNA had been copied in S stage. At that point, at a basic point during interphase (called the S stage), the phone copies its chromosomes and guarantees its frameworks are prepared for cell division. The point of this procedure is to deliver twofold the measure of DNA, giving the premise to the chromosome sets of the daughter cells.

(03.05 MC) In which of the following ways is DNA replication similar to transcription?

Nezavi [6.7K]

Answer: D. Thymine is used in replication while uracil is used in transcription.

Explanation:

Genetic information is stored in double-helixes of DNA molecules (Doxyribonuclease). In replication, two daughter strands of DNA are copied from the parent strand, while in replication, instructions stored within DNA are copied into a different form, called mRNA or messenger RNA.

Nucleotides are monomers comprising DNA, a nucleic acid that along with RNA, a ribose sugar-containing nucleotide, acts as a storage molecule to encode proteins. 5-carbon deoxyribose or ribose sugar, phosphate and one of four nitrogen bases are found in nucleotides:

Adenine (A)

Guanine (G)

Cytosine (C)

Thymine (T).

Uracil (U) found in RNA

While both contain four nucleotide bases, in RNA, uracil replaces thymine... The DNA nucleotides are involved in replication while RNA nucleotides drive transcription,
