How does synthesis new strand occur along lagging strand?
Answers
New strand synthesis :-
☆ The building blocks of DNA are nucleotides.
☆ During new strand synthesis a number of nucleotides join with one another with the primer in sequence complementary to template.
☆ DNA helix is unbounded upto a point when it appears to be a Y- shaped structure called replication fork.
☆ The DNA polymerase adding nucleotides to the primer strand in the 5’-3’ direction.
☆ The two new strands have to be formed by the growth taking place in the opposite direction.
☆ The DNA polymerase forms one new strand in a continues stretches in the 5’-3’ direction and this is called the leading strand.
☆ The other new strand is formed in small stretches in the 5’-3’ direction starting from the RNA primer.
☆ The okazaki fragments are then joined together to form a new strand by the enzyme DNA ligase.
☆ The new strand formed is called the lagging strand (Discontinues strand).
