Answer to Question #162288 in Biology for Anas Bajbouj

Question

Explain how the following strand of DNA is replicated .

G--C

C--G

T--A

G--C

Answer 1

The DNA replication requires a set of specific enzymes. First, helicase will separate the double helix into two distinct single-stranded DNA molecules: G-C-T-G and C-G-A-G. Next, the polymerase will add nucleotides following the complementary rules: C with G, A with T. These nucleotides will be linked to each other via phosphodiester bonds. As a result, two identical DNA molecules will be formed. Each molecule will contain one maternal and one daughter DNA strand.
