Multiple choice (genetics) HW help please? No guessing please!
1.
Translocation of the ribosome occurs during
elongation
termination
initiation
transcription
3.
Translation starts at _____ and reads _____.
the promoter, in groups of three bases
the promoter, one base at a time
the start codon, in groups of three bases
the start codon, one base at a time
5.
In which level of protein structure would you see hydrophobic and ionic interactions?
primary
secondary
tertiary
quaternary
9.
Which is the correct sequence for the following events:
1. Polypeptide forms tertiary structure
2. mRNA transcript attaches to ribosome
3. Peptide bonds form
4. Codon binds with anticodon
5. tRNA brings specific amino acid
6. DNA is copied
6, 2, 5, 4, 3, 1
1, 2, 3, 4, 5, 6
1, 6, 3, 5, 4, 2
None of the other choices is correct.
10.
It allows wobble in the third base of the codon.
The binding of mRNA to DNA
The entire base sequence of an mRNA molecule
The entire sequence from the promoter to the terminator of a gene
The binding of tRNA to mRNA
A.elongation
B.termination
C.initiation
D.transcription
Explanation / Answer
1-B
3-start codon , in group of three bases
5-tertiary
9-A
10-D
Note-antidodon on trna binding to codom on mrna allow third base wobbling of the codon which allow multiple codon to bind to the same trna.
