It is composed of elastic fibers in an otherwise thin homogenous layer.asal membrane, a sheet of tissue that forms the outer layer of the choroid and lies just under the pigmented layer of the retina.

There are several enzymes that 'unzip' DNA. These enzymes are collectively known as DNA helicases. DNA helicases are helix-destabilizing enzymes that bind to DNA at the origin of replication and break hydrogen bonds, thereby separating the two strands.. Solomon, Eldra P., Linda R. Berg, and Diana W. Martin. Biology. 8th ed. Belmont, CA: Thomson Brooks/Cole, 2008.
Adding nucleotides to the lagging strand Enzyme: primase (produces primers at each Okazaki fragment), DNA polymerase I and III 5. Rejoining the strands Enzyme: DNA ligase (rejoins the Okazaki fragments) Here is an image of the summary of DNA replication: http://course1.winona.edu/sberg/ILLUST/D...nswers. Best Answer: 1. Untwisting the DNA strand and forming a replication fork Enzyme: helicase (unwinds the strands), single-strand binding proteins to help stabilize the strand 2.
