DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During DNA replication, only one strand of DNA serves as a template.
A
true
B
false
Explanation: 

Detailed explanation-1: -Each strand of DNA acts as a template for synthesis of a new, complementary strand. Replication produces two identical DNA double helices, each with one new and one old strand.

Detailed explanation-2: -DNA is double-stranded, but only one strand serves as a template for transcription at any given time. This template strand is called the noncoding strand. The nontemplate strand is referred to as the coding strand because its sequence will be the same as that of the new RNA molecule.

Detailed explanation-3: -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-4: -Answer and Explanation: The parent DNA strands ac as the template during DNA replication. During DNA replication, the parent DNA molecule unzips and reveals the base pairs on either strand.
