Amniote cell specification (germ layer identity)is established before gastrulation starts, but the specification of cell type is controlled by inductive influences during and after migration through the primitive streak.

Synthesis of an Okazaki fragment displaces the RNA primer of the preceding fragment in the form of a “flap.”

the base of the flap is cleaved by the enzyme FEN1 (f lap endonuclease 1).  In this reaction, FEN1 functions as an endonuclease, but it also has a 5’–3’; exonuclease activity. In DNA repair reactions, FEN1 may cleave next to a displaced nucleotide and then use its exonuclease activity to remove adjacent material.
