Origin of replication
1)Site where the replication of a DNA molecule begins, consisting of a specific sequence of nucleotides.
2)Proteins that initiate DNA replication recognize this sequence and attach to the DNA, separating the two strands and opening up a replication bubble.
-
-
Replication Fork
Happens at the end of the replication bubble. It is a Y-shaped region on a replicating DNA molecule where the parental strands are being unwound and new strands are being synthesized.
-
Antiparallel Elongation
Leading Strand
The new complementary DNA strand synthesized continuously along the template strand toward the replication fork in the mandatory 5' to 3' direction.
Lagging Strand
A discontinuously synthesized DNA strand that elongates by means of Okazaki fragments, each synthesized in a 5' to 3' direction away from the replication fork.
Okazaki Fragments
-
It is a short segment of DNA synthesized away from the replication fork on a template strand during DNA replication. Many such segments are joined together to make up the lagging strand of newly synthesized DNA.
