Homework Answers
1. (a) Two mutations are- (i) Deletion, (ii) Insertion
(b) Both of this mutation causes change in the DNA sequence and as well as in the RNA sequence which also can change the amino acid sequence. So that the functional protein can be mutated.
(c) In case of the deletion mutation the DNA base pair is got deleted or removed but incase of the insertion mutation the DNA new base pair is been added in the old DNA sequence.
2. This type of mutation is called 'Silent mutation'.
Because this type of muatation does not make any change in the protein structure which means the mutation causes no change so that it is called the silent mutation where as other mutation causes change in the protein structure and function.
3. (a) Serine has more than one codon.
(b) Methionine has only one codon.
4. (a) After deleting the first H-
TEFAT CATATE THERAT
(b) No the sentence does not have any meaning.
(c) In this mutation one latter has been deleted which means it is 'Deletion mutation'.
5. The codon expresses the protein are-
#1. AGU UUA GCA ACG AGA UCA- Ser-Leu-Ala-Thr-Arg-Ser
#2. UCG CUA GCG ACC AGU UCA- Ser-Leu-Ala-Thr-Ser-Ser
#3. AGC CUC GCC ACU CGU AGU- Ser-Leu-Ala-Thr-Arg-Ser
So the two codon which codes for same protein are #1 & #3.
