anne ,
I think that it will generate stop codon and thus protein will be truncated.What do you think ?

i think D should be correct.
the substitution did not give any stop codon (UAG, UAA, UGA) or you guys assume that the stop codon will be generated on the complementary chain?

bobby,
What i thought is this :
:arrow: after substitution u get 5' ACT GAA TTG CGT 3'
:arrow: to read its antiparallel complementary ....(IAM READING IT FROM 3' ) UCG CUU UUC UGA...since UGA is stop codon..the protein will be truncated to 3 codons instaed of 4 .
Correct me if iam wrong thanks

asma,when i read it antiparallel,the complementary codon at the end appears to be AGU rather than UGA
:arrow: after substitution u get 5' ACT GAA TTG CGT 3'
:arrow: reading it during transcription,u get UCG CUU UUC AGU
so it doesnt turn out to be a stop codon.do correct me if i am wrong!!! :?:

Correct me if i am wrong guys, but i thought that the template strand is 3 to 5 and then the coding strand is synthesized in 5 to 3, and its the same as the mRNA except the T's are swithced with U's. This is a coding strand, so it would be transcribed exactly the same as the given strand, except you would change all the T's to U giving you
5' ACU GAA UUG CGU 3' ????

hi helpneeded!i guess its the template strand bec the q says "The nucleotide sequence encoding four amino acids", and as its only the template strand which undergoes transcription,and then then translation of the transcribed mRNA.
do correct me please if i am wrong!!!

Its the coding strand.....not the template strand

Rida, you are absolutely correct.
Insertion or deletion of a non-multiple of 3 in the DNA sequence will result in a frame shift mutation. So the protein encoded will be truncated prematurely (due to a possible stop codon down the road) or will result in an aberrant non-functional protein. Answer choice: C
