During the replication of DNA, ____
|
|
both strands of a molecule act as templates
|
|
|
the cell undergoes mitosis
|
|
|
only one strand of the molecule acts as a template
|
|
|
errors never occur
|
Explanation:
Detailed explanation-1: -During DNA replication, both strands of the double helix act as templates for the formation of new DNA molecules. Copying occurs at a localized region called the replication fork, which is a Y shaped structure where new DNA strands are synthesized by a multi-enzyme complex.
Detailed explanation-2: -During the process of replication, both the strands of DNA are replicated, thus both acting as a template for the newly synthesised strands.
Detailed explanation-3: -The coding strand is the DNA strand whose base sequence is similar to its primary transcript (RNA). This strand contains codons, while the non-coding strand contains anticodons. The coding strand serves as a template for producing complementary RNA.
