Dr. Klans Lectures Flashcards
1
Q
What is always the first amino acid in translation>?
A
Methionine, AUG
2
Q
AminiacytRNA
A
is a tRNA with a specific amino acid covalently bound at 3’ end
3
Q
where is the anticodon located on?
A
the tRNA
4
Q
where is the codon located?
A
the mRNA
5
Q
Where are ribosomes assembled?
A
In the nucleolus of the nucleus
6
Q
what are the two points for specificity of amino acid incorporation into a protein during translation at the tRNA level
A
1.Matching correct amino acid to correct tRNA (specificity of enzyme)
2.Correct base-pairing
of codon and anticodon (specificity of base pairing)
7
Q
what is monocistronic?
A
- One gene codes for one protein
- Eukaryotic genome
8
Q
what is polycistronic?
A
- One gene codes for more than one protein
- Prokaryotic genom e
9
Q
in prokaryotes what is the mRNA sequence called?
A
Shine-Delagarno
