The DNA polymerase enzyme produces a new DNA strand during DNA replication
What unzips DNA strand is a particular protein called Helicase. Helicase unwinds DNA's double helix at the replication fork.
no replication makes a whole new strand of identical DNA while repair just replaces or cuts out mutations in the DNA strand
Two - the leading strand and the lagging strand.
replicated DNA is made of one old strand and one new strand.
When DNA is replicated, the new double-strand contains one old strand and one new strand. This means that one of the old strands has been conserved, making DNA replication semi-conservative.
DNA Replication is semi-conservative because each DNA molecule is composed of 1 old strand and 1 new strand
The DNA polymerase enzyme produces a new DNA strand during DNA replication
semiconservative replication - original DNA double strand will unwind into 2 strands, so one original strand will serve as a template for synthesizing a new complementary strand , thus forming a new DNA (one with old strand and one with a new strand)
leading strand
Refers to semi-conservative replication of DNA. One strand of the old DNA is used as a template to replicate the other, new, strand of DNA. Thus you have four from two, but two of the four are old strands while the other two strands are new. Thus the name semi-conservative replication.
The DNA replication fork is where the replication origin forms the Y shape. The replication fork moves down the DNA strand to the strand's end, resulting in every replication fork having a twin.
After DNA replication, each new molecule has one strand of the original DNA molecule and the other strand is composed of new nucleic acids. This is due to the semi-conservative replication of DNA.
