given codon is 5' - ATG- TCC- TCG- AAT - TTT- CCC- 3'
coding for amino acids - 5'- Met- Ser- Ser- Asn- Phe- Pro- 3'
by deleting , the base T and C from 3rd codon seuence TCG we can obtain the new sequence of amino acids resulting from frame shift mutation.
the obtained sequenc is :
5'- ATG- TCC- GAA- TTT- TCC- 3'
5' - Met - Ser - Glu- Phe - Ser- 3'
5'-ATG-TCC-TCG-AAT-TTT-CCC-3' if a student induces a 2-nucleotide deletion to this sequence resulting in a frameshift mutation,...
please help with #4 and #5
question 5 of 5
the cross lines indicate deletion of the nucleotides.
what type of mutation is this? what is the resulting polypeptide
sequence?
3'- GTT - TAC - CTT - -CTC--TCC -TCA -GAC - ATC -GCA
-5' (template strand)
5' - CAA - ATG - GAA - -GAG--AGG - AGT - CTG- TAG -
CGT - 3' (non-template/coding strand)
answer: It's a ___________________mutation.
Final polypeptide sequence is N' - Met - GLU

A single mutation has occurred in the following DNA sequence. 5' ATG AAA TTA CCA 3' wild-type (normal) sequence 5' ATG AAG TTA CCA 3' mutant sequence (a) Identify and classify the mutation according to its molecular structure (i.e., insertion, deletion base substitution (transversion), or base substitution (transition)). Briefly explain why you selected this classification (1.75 marks) (b) Identify and classify the mutation according to its functional effects (i.e., frameshift, missense, nonsense, or silent). Briefly explain why you selected this...
Some amino acids are post-translationally removed from the
C-terminal end of the beta-lactamase enzyme from B.
imaginarium (i.e. - after it is translated and
released from the ribosome, a protease chews off a some amino
acids). The wild-type enzyme, which has had the amino
acids removed from the Cā-terminus, is 246 amino acids in length
and the C-terminal amino acids are shown below aligned with the
C-terminal amino acids of a frameshift mutant, which ā due to a
frameshift mutation -...
5 pts Question 23 Life on Earth uses 3 nucleotide long code words, with 4 letters in the alphabet to encode 20 amino acids. DNA on the planet Arth only contains A, G and C. In addition, proteins on Arth are made from 26 different amino acids. What is the minimum number of nucleotides in a codon needed to code for life on Arth? Hint: In humans a 3-letter code can represent 4 x 4 x4 = 64 amino acids...
