Which choices describe DNA replication?
|
semiconservative
|
|
produces two pieces of DNA identical to the original
|
|
products are half original and half new
|
|
all of the above

Explanation:
Detailed explanation-1: -The result of DNA replication is two DNA molecules consisting of one new and one old chain of nucleotides. This is why DNA replication is described as semi-conservative, half of the chain is part of the original DNA molecule, half is brand new.
Detailed explanation-2: -DNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. New DNA is made by enzymes called DNA polymerases, which require a template and a primer (starter) and synthesize DNA in the 5’ to 3’ direction.
