Fatty acids from Glycolipids and phospholipids, on the other hand, have two hydrophobic chains that are too bulky to fit into the a spherical shape as micelles do. Thus, they preferred to form glycolipids and phospholipids as lipid bilayers, which are discussed in the next section.
DNA Helicase-The enzyme responsible for separating the two strands of DNA in a helix so that they can be copied during DNA replication. DNA Ligase-The enzyme responsible for sealing together breaks or nicks in a DNA strand. Responsible for patching together Okazaki fragments on the lagging strand during DNA replication.
Explain how the structure of DNA, suggested by Watson and Crick, is a mechanism for how it replicates. The two strands are separated and then each strand's complementary DNA sequence is recreated by an enzyme called DNA polymerase.This enzyme makes the complementary strand by finding the correct base through complementary base pairing, and bonding it onto the original strand.As DNA polymerases can only extend a DNA strand in a 5â² to 3â² direction, different mechanisms are used to copy the antiparallel strands of the double helix.his enzyme makes the complementary strand by finding the correct base through complementary base pairing, and bonding it onto the original strand.
