Homework Answers
Ans) It should be noted that DNA consists of four bases namely Adenine,Guanine,Cytosine and Thymine. Wheras, RNA has Uracil,Guanine,Cytosine and Adenine. Thymine is not found in the RNA.
Since, ATT sequence has Thymine in it, this is DNA sequence and not RNA sequence because Thymine is not found in the RNA sequence as discussed above.
GAA sequence is transcribed into CUU which codes for Leucine amino acid (from codon chart)
AAT sequence is transcribed into UUA which codes for Leucine amino acid (From codon chart).
Even when 2 out of 3 nucleotides are different, they are still coding for the same amino acid i.e Leucine.This type of mutation is referred to as Silent mutation.

In protein biosynthesis Question options: A. each amino acid recognizes its codon on the mRNA template because of structural specificity. B. exactness of read-out is assured by the presence of traces of DNA on the ribosome. C. each amino acid is first attached to tRNA that has an anticodon specific for the amino acid. D. a given codon-anticodon pair must have identical base sequences to avoid the formation of degenerate proteins. E. each amino acid recognizes its codon through recognition...
