DNA Basics

What is DNA? Where is it located?

Name the 3 parts of a nucleotide.

Which 2 parts of a nucleotide make up the sides of the ladder?

What are the base pairing rules of replication?

What type of biomolecule is helicase?

• Enzyme

• Sugar

• Triglyceride

• Nucleotide

When does replication take place?

• G1

• S

• G2

• Mitosis

WHERE does replication take place?

• Cytoplasm

• Ribosome

• ER

• Nucleus

DESCRIBE semi-conservative replication and EXPLAIN why it decreases the chances for mutations.

Replicate the following DNA template strand:

ATT-TTC-CGG

WHY is replication important to the cell?

• To make proteins so the organism can survive

• To express genetic material outside of the nucleus

• So all cells are different in multicellular organisms

• So that each new cell has an identical copy of DNA before it divides
