DNA Replication, Transcription, Translation

What part of a nucleotide accounts for the genetic variation between individuals?

• phosphate
• nitrogenous base
• deoxyribose
• sugar

If one strand of DNA has the sequence TTACCG, the sequence of the other strand of the same molecule will be

• AATGGC
• TTACCG
• AACGGC
• AATGGG

Once replication in a DNA molecule is complete, each new DNA molecule contains 

• two new strands.
• 3 exact copies of strands.
• one new strand and one old.
• two old strands.

Which enzyme copies DNA?

• DNA polymerase
• DNA helicase
• RNA polymerase
• RNA helicase

What are the functions of genes?

• instructions for producing proteins
• instructions for producing DNA
• instructions for producing lipids
• they have no function

What does mRNA do?

• provides information from DNA to ribosomes
• transfers amino acids to the ribosomes
• makes up ribosomes
• builds proteins

What does tRNA do?

• provides information from DNA to ribosomes
• transfers amino acids to the ribosomes
• makes up ribosomes
• builds proteins

What is the process that copies information from DNA into RNA?

• protein synthesis
• transcription
• translation
• DNA Polymerase

Which enzyme has the job of unzipping the double helix?

• Helicase
• Polymerase
• Ligase
• Primerase

If a strand reads:
3' A A A T T T C 5'
The matching strand would read...

• 5' T T T A A A G 3'
• 3' T T T A A A G 5'
• 5' A A A T T T C 3'
• 3' U U U A A A G 5'
