c. both utilize the same nucleotides.
d. the polymerases for both require a Mn²⁺ cofactor for activity.
e. both have extensive processes to correct errors.

Answer 1

Replication requires a template and a primer, while transcription only requires a template. Copies of both DNA strands are made during replication, but only one strand is transcribed during transcription. Both replication and transcription utilize the same nucleotides.

Step-by-step explanation:

The relationship between replication and transcription of DNA can be understood by considering the following statements:

1. Replication requires both a template and a primer, whereas transcription requires only a template. During replication, both strands of the DNA molecule are unwound and used as templates to synthesize new DNA strands. The process requires a primer to initiate the addition of nucleotides. In contrast, during transcription, only one of the two DNA strands (the template strand) is used to synthesize an RNA molecule, and no primer is required.
2. Copies of both DNA strands are made during replication, but only one strand is transcribed during transcription. In replication, both the leading and lagging strands are synthesized, resulting in two identical daughter DNA molecules. In transcription, only one of the DNA strands (the template strand) is used as a template to synthesize a complementary RNA molecule.
3. Both replication and transcription utilize the same nucleotides. Both processes involve the use of nucleotides to build new DNA or RNA strands. The nucleotides used in DNA replication and transcription are adenine (A), cytosine (C), guanine (G), and uracil (U).
