Question

Think about dna replication versus rna transcription - which of the following statements is true only of dna replication?

a. the process is extremely fast once it is initiated.
b. the entire template molecule is represented in the product.
c. the process occurs in the nucleus of a eukaryotic cell.
d. it uses rna polymerase.
e. it makes a new molecule from its 5' end to its 3' end.

Answer 1

The statement true only of DNA replication is 'b. the entire template molecule is represented in the product', as DNA replication duplicates the entire sequence of the DNA template molecule.

Step-by-step explanation:

When comparing DNA replication to RNA transcription, the statement that is true only of DNA replication is: b. the entire template molecule is represented in the product. DNA replication involves the entire DNA molecule, and each strand of the original DNA serves as a template for the creation of a complementary strand. Hence, the entire sequence of the template molecule is duplicated. In contrast, RNA transcription typically involves only a portion of the DNA, transcribing just the gene (or genes) needed to produce a particular RNA molecule.

Furthermore, DNA replication requires DNA polymerase, not RNA polymerase which is used in RNA transcription, making statement d incorrect for replication. The replication process occurs in the nucleus of eukaryotic cells, but so does transcription, invalidating option c. Additionally, DNA replication is indeed an anabolic process as it involves the synthesis of new molecules.
