Students have asked these similar questions
what is the translation factors(s) most involved in decoding
a) IF1,IF2,IF3
b) N-fMet-tRNAfMet and mRNA
c) EF-Tu
d) EF-G
e) release factor and ribosome recycling factor
The ribosome is needed for translation of mRNA
(a) because it has the enzyme for adding amino acids to the 5’ end of a tRNA (b) because the ribosomal RNA contains the codon which determines the sequence of amino acids in a protein (c) because it positions tRNA and mRNA so that correct pairing of codon and anti-codon can occur (d) because it has an enzyme that removes introns from mRNA (e) all of the above
The ribosome is needed for translation of mRNA
(a) because it has the enzyme that forms peptide bonds between amino acids (b) because the ribosomal RNA contains the codon which determine the sequence of amino acids in a protein (c) because it contains the enzyme that links the amino acids and tRNA (d) because it has enzyme that removes introns from mRNA (e) all of the above
