Mutation # | DNA Sequence change | mRNA codon change (original > mutant) | Amino acid change (or

Let's solve the question and here we are discussing about the sequence that is ATA. Here it is T

So first, whenever you're trying to make your complementary strand of messenger RNA, you need to

Mutation is the change in the sequence of basis. Now this can happen either in the DNA or RNA. T

So while seeing the question let's further move to the answer. So let's see here that genetic co

Hello students, in the question this DNA strand is given and in the first question we have asked

Question

Mutation # | DNA Sequence change | mRNA codon change (original > mutant) | Amino acid change (original > mutant) | Type of mutation (silent, missense, nonsense) --- | --- | --- | --- | --- 1 | Coding ATA -> ATC, Template TAT -> TAG | AUA > AUC | Ile > Xxx | 2 | Coding TAT -> TAA, Template ATA -> ATT | UAU > NNN | Xxx > Xxx | 3 | Coding AGT -> AGG, Template TCA -> TCC | NNN > NNN | Xxx > Xxx | D. Imagine a ‘G’ were inserted at the beginning of the original coding DNA sequence from part B as indicated here: 5'-GACG ATA TAT AGT GCT-3' 1. Write out the resulting mRNA and amino acid sequence. New mRNA = 5'- GAC GAU AUA UAG UGC U-3' New amino acid sequence = Asp Asp 2. What kind of mutation has occurred? Highlight 3. Do you think this mutation will affect the function of the protein? Why or why not? Highlight 3. Unrepaired DNA damage can lead to mutations. a. DNA damage can be caused by mutagens in the environment. Give an example of a mutagen and the kind of DNA damage it causes. Example Mutagen | Type of damage caused by the mutagen b. A type of DNA damage called ‘depurination’ is a common, spontaneous form of DNA damage in which the nitrogenous base of a purine nucleotide is lost. How does the loss of the base affect the genetic information? Highlight
