Module 9 Flashcards
1
Q
DNA transcription
A
occurs in the nucleus
RNA polymerase is the main enzyme
a single strand of mRNA is made complementary to the DNA
2
Q
Codon
A
a sequence of three mRNA bases
3
Q
ribosome
A
the site of protein synthesis
4
Q
tRNA
A
RNA that brings an amino acid to a ribosome
5
Q
anticodon
A
sequence of three tRNA bases that is complimentary to an mRNA codon
6
Q
RNA translation
A
occurs in the ribosomes
tRNA delivers amino acids to build a protein
continues until a stop codon is reached
7
Q
Instead of T
A
there is a U
8
Q
Mutation happens during
A
DNA replication
9
Q
frameshift mutations
A
caused by an insertion or deletion that changes the three-letter groupings
10
Q
Viruses include
A
genetic material covered by a protective protein layer
viral envelope
glycoprotein to attach to host cells
