Q1: on the ribosome, the mRNA is read from ____ is a series of three nucleutides called_____
a. 5' to 3' ,, Codons
b. 5' to 3' ,, anticodons
c. 3' to 5' ,, codons
Q2: which of the following features of eukaryotic ribosomes in translation initiation is FALSE?
a. it uses an initiator tRNA that carries a methaionine
b. the large subuinit of the ribosome is important for binding to the mRNA
c. the large and small subunits of the ribosome combine once the initiation complex recognize the AUG start codon.
Q3: which of the following methods is NOT used by eukaryotic cells to regulate the amount of protein in the cell?
a. Operons
b. Riboswitches
c. miRNAs
PLEASE ANSWER ALL QUESTIONS
Homework Answers
Solution:
1. a. 5' to 3', Codons (mRNA are translated in the 5'→3' direction, Codons are composed of three-nucleotides).
2. c. (it is 40S ribosomal subunit bound with the
methionyl tRNA and eIFs, which scans the mRNA and identifies the
the AUG start codon).
3. a (Primarily a prokaryotic mechanism).
Hope it helps

3. What are the “translator” molecules that recognize a codon in the mRNA and deliver the correct amino acid? 6. If each amino acid was encoded by a single codon, what is the minimum number of amino-acyl tRNA synthetases required for translation? 7. Looking at the codon table, if there was a unique aminoacyl-tRNA synthetase required for each anticodon, what is the minimum required? 9. If an aminoacyl-tRNA synthetase recognized any nucleotide (purine or pyrimidine) in the 5’end of the anticodon,...

Question 9:
The genetic code is read in groups of three nucleotides, called
codons, in mRNA that specifies for a particular amino acid.
tRNA molecules act as the amino acid carriers that by correctly
pairing with the codon on mRNA can deliver the correct amino acid
to the ribosome during translation. At the tip of each tRNA
molecule is a group of three nucleotides called an anticodon and at
the other end is where the corresponding amino acid is attached...
