A particular mRNA is 300 nucleotides long. If a mutation in the middle of the sequence changed a codon from a AAA to a UAA then
what would be a reasonable prediction? O The protein coded by this mRNA would not form due to a failure in initiation. O The protein coded by this mRNA would be the same size. O The protein coded by this mRNA would be shorter The protein coded by this mRNA would kill the cell. O The protein coded by this mRNA would be longer.
The translation process translates the nitrogenous bases present in the mRNA to the amino acids which bind to form a protein molecule.
The nitrogenous bases are read from the 5' to 3' direction in the form of triplets called codons. Each codon codes for a specific amino acid.
In the given question when a mutation changes the codon AAA which codes for lysine to UAA which has no amino acid thus it acts as a stop codon. This results in the shorter proteins as the translation process gets stopped at UAA codon.
The characteristic that is found in whale but not in phytoplankton is : heterotrophic Heterotroph refer to the organisms that cannot fix carbon and uses organic carbon as a source of energy
