RNA

300

List two similarities between DNA and RNA

Both have base pairs C-G, 

Both have sugar phosphate back bone

300

List two differences between DNA and RNA

One is double stranded the other is single stranded

RNA has U while DNA has T

RNA can leave the nucleus

300

What does semiconservative mean in DNA?

Two copies of the original DNA molecule are produced, each copy replicating the information from 1/2 of the DNA

400

What is the first step in DNA replication

Unwind the double helix 

400

Which enzyme is responsible for un-zipping the double helix?

Helicase

400

Which enzyme builds the complementary strands during DNA replication?

DNA Polymerase

400

When a DNA gene is copied into a strand of mRNA

Transcription

400

When mRNA is read at the ribosome to assemble amino acids and build a protein

Translation

23% A, 23% U, 27% G, 27% C

500

When does DNA replication occur?

S phase of interphase during the cell cycle

500

Why is DNA considered semi-conservative?

It is half old/half new

500

What does anti parallel mean in DNA replication?

The DNA is being made at the same time in different directions.
