Multiple Choice

Why is DNA replication considered fundamental to heredity?

1

Because it ensures genetic information is passed to the next generation

2

Because it creates new proteins directly

3

Because it determines eye color only

4

Because it only occurs in plants

Conservative

15

Multiple Choice

Question image

What does it mean for DNA replication to be semi-conservative?

1

-1 old and 1 new

-The result is that there is 1 new identical DNA molecule

2

-2 old and 3 new

-The result is that there is 1 new identical DNA molecule

3

-4 old and 4 new

-The result is that there is 1 new identical DNA molecule

4

-3 old and 2 new

-The result is that there is 1 new identical DNA molecule

Multiple Choice

Question image

What are the 3 steps of DNA Replication?

1

-double stranded

-it is a double helix

-a polymer made of small, repeating monomers (nucleotides)

2

1. Enzymes unzip/unwind DNA double helix

2. Single free nucleotides floating in the nucleus pair with open strands of A, T, C, and G

3. Two, complete identical DNA molecules are formed

3

Adenine (A)

Guanine (G)

Cytosine (C )

Thymine (T)

4

There are not 3 steps of DNA Replication
