Amoeba Sisters Video Recap DNA Replication

Label DNA parts: 6 deoxyribose sugars, 6 nitrogenous bases, 3 hydrogen bonds, green phosphates. DNA replicates before cell division to copy genetic info. Key enzymes: helicase unzips strands, DNA polymerase builds new DNA.

Amoeba Sisters Video Recap: 0 4 Repf/cot/on
In the below DNA diagram, label ONE of
each bolded term:
2. Deoxyribose (sugar). Total number in
image? 6
3. Nitrogenous base. Total number in
image? 6
4. Hydrogen bond. Total number in Image?

1. To understand DNA replication, we need to
understand the "why.1 Why does DNA need to
replicate before cells divide?
Dna needs to replicate before cells divide because new
strand (daughter) needs part of the parent cell in order to
replicate and then divide after replication is done
5. Phosphate. Green circles
d. Label 5 to 3' strand a n d 3' to 5' strand ■
3. DNA Replication has many key players! These are just a few of the major key player enzymes. In your
own words, describe each of their functions in DNA replication.
Helicase: Unzips the 2-strand DNA into sing e strand Unzips t h e 2 -strand DNA into s. n g e

DNA polymerase: Builds a r e w s e t o f DNA
