Protein Synthesis Exam Questions and
Answers
Protein
An organic molecule made up of 1 or more chains of amino acids
messenger RNA (mRNA)
carries the genetic code from DNA in the nucleus to the ribosomes in the
cytoplasm
Transcription
first step of protein synthesis when DNA is transcribed (copied) into mRNA
Translation
Second step of protein synthesis when ribosomes read one codon at a time and
tRNA delivers the matching amino acid.
DNA base pairing rules
A-T
C-G
Nitrogen bases of RNA pairing rules
T-A, A-U,
C-G, G-C
Gene
section of a chromosome that carry the code for a particular trait.
trait
an observable characteristic in an organism. Example: hair color
What mRNA would complement this DNA molecule:
-ATCGTCAAG-
-UAGCAGUUC-
