Which of the following is the beginning step of DNA replication?
|
|
The enzyme primase starte the complementary strand of DNA with short segments of RNA.
|
|
|
The process of elongation adds DNA nucleotides to each complementary strand of DNA
|
|
|
The enzyme DNA polymerase bonds to the RNA primers
|
|
|
the enzyme helicase unzips the DNA double helix
|
Explanation:
Detailed explanation-1: -The very first step in DNA replication is unzipping the double helix of the DNA molecule, the unwinding of DNA occurs by enzyme helicase and gyrase. After unwinding the DNA forms a replication fork and both the strands act as a template for the formation of new strands.
Detailed explanation-2: -The Y shaped DNA strand is formed due to the unzipping of the DNA. This process takes place with the help of an enzyme called helicase.
