Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process results in two copies of a double helix of DNA?
A
DNA replication
B
Transcription
C
Translation
D
Chempsynthesis
Explanation: 

Detailed explanation-1: -Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.

Detailed explanation-2: -During the G1 phase the cell grows and also carries out normal cellular functions. In the synthesis (S) phase the DNA is replicated, resulting in two copies of each of the chromosomes.

Detailed explanation-3: -During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication.

Detailed explanation-4: -The replication process 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.
