From DNA to Protein

Which of the following nitrogen bases is NOT found in RNA?

• adenine

• guanine

• thymine

• cytosine

RNA is different from DNA because RNA:

• is single-stranded

• contains the sugar deoxyribose

• is a double helix

• contains the nitrogen base thymine

The enzyme that separates DNA by breaking the hydrogen bonds that link the nitrogen bases is:

• amylase

• DNA polymerase

• RNA polymerase

• RNA helicase

DNA is important because:

• it contains the hereditary information for an organism.

• it contains the instructions for making proteins.

• All of the these

• None of the these

The three-nucleotide sequence on mRNA that specifies an amino acid or "start" or "stop" signal is called:

• a codon

• an anticodon

• a protein

• a nitrogen base

This type of RNA carries the instructions for making a protein from a gene to the site of translation:

• uRNA

• mRNA

• rRNA

• tRNA

A three-nucleotide sequence on a tRNA that recognizes a complementary sequence on mRNA is called:

• a codon

• an anticodon

• a protein

• a nitrogen base

The process of transferring genetic information from a gene in DNA to mRNA is called:

• replication

• translation

• anagrams

• transcription

The process of putting together the amino acids that make up a protein is called:

• replication

• translation

• anagrams

• transcription

The function of mRNA is to:

• synthesis DNA

• carry information from genes to ribosomes

• form ribosomes

• transfer amino acids to ribosomes
