B. thymine
C. cytosine
D. guanine

2.What sugar does RNA contain?
A. deoxyribose
B. ribose
C. glucose
D. all of the above

3.In transcription, thymine on the DNA molecule is paired with
A. uracil.
B. guanine
C. adenine
D. cytosine

4.During ______, instructions for making a protein are transferred from a gene to an RNA molecule.
A. translation
B. transcription
C. DNA replication
D. all of the above

5.Transcription makes a complementary _______ strand of the DNA.
A. RNA
B. DNA
C. peptide
D. none of the above

6.Ribosomes contain which of the following?

B. rRNA
C. tRNA
D. all of the above

7. The amino acids are carried to the ribosome by a ______ molecule.
A. mRNA
B. tRNA
C. rRNA
D. DNA

8.During initiation, mRNA binds with a

B. nucleus
C. chromosome
D. ribosome

9. Mutations are
A. very common
B. rare
C. always deadly
D. none of the above

10.When a whole segment of a gene is lost, it is called a(n)
A. gene alteration
B. gene rearrangement
C. insertion
D. deletion


THANKS to whoever helps me!! 10 points

1. A, uracil is only found in RNA
2. B, hence the name RIBOnucleic acid
3. C
4. B, remember transcription is from DNA to RNA
5. A
6. B, which stands for ribosomal RNA
7. C, which stands for transfer RNA (it 'transfers' the amino acids to the ribosome)
8. D
9. B
10. D (the segment is 'deleted')

Hope I could help!
