2. Where in the cell does DNA replication occur?

Cytoplasm

Nucleolus

Nucleus

Ribosomes

POINT VALUE: 3 points

--------------------------------------...

3. Which of the following is a correct complementary DNA strand to A-A-C-G-T-A-C

T-T-G-C-A-T-G

A-A-C-G-T-A-C

G-C-T-A-C-G-A

C-C-A-T-C-G-A

POINT VALUE: 3 points

--------------------------------------...

4. Why is the “complementary” way the nitrogen bases combine in DNA important?

It allows for the double helix shape.

It keeps the strand from “unzipping” at the wrong time.

It ensures that the information on the DNA will be replicated for new cells.

It helps the enzymes begin the replication process at the correct site.

5. Name the scientists who proposed an accurate model of DNA in 1953.

Answer 1

jeeze! Everyone dont get so angry! this is what the internet was made for! And no where does it way for this test --"You may not use Yahoo answers!" So--  This is just being innovative using creative resources!.....

Answer 5

Vane...I have questions for you...

1. Does your teacher know you consistently put your math and science quizzes on this web site so others can give you the answers?

2. Do you care that this is cheating?

3. Do you think your teacher will care that you are cheating?

4. If you always cheat...never try to do the work yourself...will you ever learn enough to get a good job or will you be asking..."Would you like fries with your order?" for the rest of your life? (no offence to burger flippers...)

Show me documented proof that your teachers think this is acceptable...(ie a letter with a school email address to reply to from your teachers) and I will personally anwer every biology question you get for the rest of the year....otherwise...STOP CHEATING AND DO YOUR HOMEWORK!

Answer 6

1869

Nucleus

( T-T-G-C-A-T-G).

It ensures that the DNA will be replicated for new cells
