Mutations change the DNA sequence. This might change the amino acid sequence. If it does it might have an impact.
Have a look at these two Alleles: Allele B (original) and Allele b (mutant). See if you can find the difference in the DNA sequence because of this mutation.
Transcribe both alleles and copy the mRNA into the holding box. Then Translate both alleles and see what the result of the change in DNA sequence is for the amino acid sequence and the resulting protein.
Transcribe the 2 lots of DNA from the 2 Chromosomes into 2 strands of mRNA
Chromosome 15 Maternal
OCA gene (eye colour)
Allele B
Chromosome 15 Paternal
OCA gene (eye colour)
Allele b
Paste your 2 mRNA strands into these boxes until you are ready to do the Translation Activity
Copy and paste your mRNA strands into their "Start Translation" boxes, and then Start Translation 😁
