Ch 13 & 14 (DNA, RNA, & Protein Synthesis) Test Review

Front

What does the pentagon shape represent in the DNA molecule?

Back

The sugar deoxyribose.

Front

If a DNA molecule contained 10 thymine and 20 cytosine, how much adenine would it contain?

Back

10

Front

Label the process of protein synthesis: What does tRNA do?

Back

tRNA brings amino acids to the ribosome during protein synthesis.

Front

What are the parts of a DNA nucleotide?

Back

1 - phosphate, 2 - deoxyribose sugar, 3 - thymine.

Front

If the green structure is adenine, what would the purple structure represent?

Back

Thymine.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the site where proteins are synthesized.

Front

What is the function of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome.

Front

What are the four nitrogen bases in DNA?

Back

Adenine, Thymine, Cytosine, Guanine.

Front

What is a peptide bond?

Back

A peptide bond is the bond that links amino acids together in a protein.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.
