Explanation: notes
<span>Collagen fibers. You can identify these as collagen fibers in part because they are fairly straight rather than springy. Collagen is a fibrous protein that is found in human connective tissue - specifically collagen can be found in human skin, bones, cartilage, and ligaments.</span>
The new mRNA formed is AUG CCC UAU AUG GUA GAG UGU AG
Explanation:
Frameshift mutation is a condition when either a nucleotide is added or deleted and the code is no longer triplet codon. This change causes the shifting of the frame of DNA sequence and the coding of amino acid is affected because mRNA is transcribed according to the mutated DNA sequence.The different amino acid than expected is the outcome.
In the given mRNA strand:
mRNA : AUG CCC CUA UAU GGU AGA GUG UAG
the condition given is if frame shift mutation takes place in 3rd nucleotide in second codon, the third C is lost, the resulting mRNA is:
new mRNA formed is AUG CCC UAU AUG GUA GAG UGU AG
The sequence of amino acid will change and also there will be a loss of amino acid in the polypeptide as only 2 nucleotides in the triplet codon is there.
In DNA and protein, hydrogen, sulphur, oxygen and selenium are some elements which are found in DNA and protein.
