Protein Synthesis - bio 1

Transcription is the process in which

• Information from DNA is copied to an mRNA molecule

• Information from mRNA is used to create amino acids

• Information from RNA is copied to a tRNA molecule

• Information from DNA is copied to an rRNA molecule

Translation is the process in which

• Information from DNA is copied to mRNA

• Information from mRNA is copied to rRNA

• Information from mRNA is used to make proteins

• Information from DNA is copied to tRNA

What would the complementary DNA strand look like if the original strand has the bases GAC? (remember DNA has T instead of U)

• CUG

• GAC

• CTG

• ATG

What would the bases of an mRNA codon be, based on a DNA strand GAC? (remember mRNA has U instead of T)

• CTG

• GAC

• CUG

• GTC

A nucleotide is...

• the subunit of lipids

• the subunit of carbohydrates

• the subunit of amino acids

• the subunit of DNA

If you see a three-part molecule made of ribose, phosphate, and a U-base, you are looking at a

• DNA nucleotide

• Amino Acid

• RNA nucleotide

• Monosaccharide

If you see a three-part molecule made of ribose, phosphate, and a T-base, you are looking at a

• RNA nucleotide

• DNA nucleotide

• Both of the above

• Neither of the above

Which can be found ALWAYS inside the nucleus of a eukaryotic cell?

• DNA

• mRNA

• tRNA

• Lipid

A C base always pairs with which letter?

• G

• A

• T

• U

What does antiparallel mean?

• DNA strands are perpendicular to each other

• DNA strands are parallel, but run in opposite directions

• It's when DNA is unzipped and the strand is no longer parallel

• It's a synonym of parallel
