4.

How does this model represent replication?

a)

each new molecule of DNA is made of two old strands

b)

each new molecule of DNA is made of ONLY new strands

c)

each new molecule of DNA is made of one old strand and one new strand

5.

The diagram shows the process by which DNA copies itself. What is the name of this process and how do we describe the model?

a)

replication, conservative

b)

transcription, conservative

c)

protein

c)

mRNA

d)

rRNA

7.

What process is pictured and where does it happen?

a)

translation, nucleus

b)

transcription, nucleus

c)

translation, ribosome

d)

transcription, ribosome

8.

What molecule leaves the nucleus with the genetic message and why?

a)

mRNA, so the genetic code can be taken to the ribosome

b)

DNA, so the genetic code can be taken to the ribosome

c)

mRNA, so the proteins can be made in the nucleus
