DNA and Protein Synthesis Review

A nucleotide is made up of three parts:  which of these is not one of those parts?

• sugar
• phosphate
• amino acids
• base

A strand of DNA that looks like a twisted ladder is called a _____________________

• triple twist
• corkscrew
• double helix
• chain reaction

__________________________ are proteins that are made from many sub units.

• Nucleic Acids
• Armor
• Sugars
• Amino Acids

What base pairs with adenine?

• phosphate

• cytosine

• thymine

What base pairs with thymine?

• adenine

• guanine

• cytosine

• limousine

What base pairs with guanine?

• cytosine

• guanine

• thymine

• sugar

What base pairs with cytosine?

• guanine

• adenine

• thymine

• magazine

Which enzyme has the job of unzipping the double helix?

• Helicase
• Polymerase
• Ligase
• Primerase

Sometimes, DNA is called "semi-conservative." Why might this be?

• The old strand is "conserved" and used to make the new strands
• Uracil is "conserved" in that it is only used to make the new strands
• ATP is "conserved" via the usage of facilitated diffusion
• Ligase is "conserved" in that it is denatured by the process

How does RNA differ from DNA?

• RNA contains uracil and deoxyribose
• RNA contains ribose and thymine
• RNA contains uracil and ribose
• RNA contains adenine and ribose
