Replication
Key Points:
- copying DNA- takes place during cell reproduction
- copies chromosomes
- hydrogen bonds are broken
- a new (replica) DNA strand is pulled together with an original
- where the DNA splits is known as a fork
- Adenine pairs with Thymine
- Cytosine pairs with Guanine
- Guanine pairs with Cytosine
- Thymine pairs with Adenine
In Depth:
First, the double helix DNA strand is flattened out. Then a strand of DNA is split. An enzyme, Helices, unzips the DNA strand and breaks the hydrogen bonds. Free roaming nucleotides that are floating around attach to the DNA strand. An enzyme, polymerase, pulls the nucleotides to the DNA strand. This creates 2 identical strands. The strands are half new and half original.

Good information! I would just list what all of the base pairs are.
ReplyDeleteGood Information, but you are missing some information, like what the base pairs are.
ReplyDeleteNIce video and visual references, you just need to make sure and label the base pairs of DNA.
ReplyDeleteI love the video! It really helps with explaining what replication does. Great Job!
ReplyDeleteI like how everything is bulleted and clearly written out. Having it this way makes it easier for me to study and know the material. Just make sure you get all the information.
