8.4 Translation/Mutation Flashcards
1
Q
Role of each of the following in the process of translation:
mRNA
tRNA
rRNA
A
mRNA- contains message/code for amino acid sequences
tRNA- transfers amino acids and pairs with anticodons
rRNA- matches mRNA and tRNA and joins amino acids to synthesize proteins
2
Q
Define point mutation and what are the types?
A
substitutes 1 base
-silent, missense, and nonsense
3
Q
Define frameshift mutation and what are the types?
A
inserts or deletes a base or few bases
- extensive missense, immediate nonsense, or insert/delete 3 bases or 1 amino acid
4
Q
Define translation.
A
The process of making amino acids/polypeptide chains from mRNA
5
Q
What are the start and stop codons?
A
Start- AUG
Stop- UAA, UAG, UGA
6
