Answer:
The mRNA that was transcirbed determines what amino acid would be attached.
Explanation:
For instance, lets say the complementery mRNA codon said GAU, the amino acid assosioted with this codon is aspartic acid. If the sequence were to change to GAA then the amino acid would be glutamic acid. I hoped this helped! If need any clarifications tell mehhhhh!!
Yes, any change in the gene sequence WILL AFFECT the mRNA transcribed from the DNA. However, a change in the mRNA sequence MAY or MAY NOT affect the protein translated from the mRNA.
During gene transcription, a fragment of DNA is used as a template to create an exactly complementary messenger RNA (mRNA) sequence.
In consequence, any change in the DNA nucleotide sequence will produce a change in the complementary mRNA sequence.
Subsequently, this mRNA travels to the ribosome where it is used as a template to create a protein by a process called 'translation'.
During translation, triplets of nucleotides or 'codons' are read by the ribosome in order to add specific amino acids in the nascent polypeptide chain.
There are codons that encode for the same amino acid, thereby a change in the mRNA sequence may or may not produce changes in the protein synthesized from the mRNA. It is for that reason that the genetic code is said to be redundant.
In conclusion, any change in the gene sequence WILL AFFECT the mRNA transcribed from the DNA. However, a change in the mRNA sequence MAY or MAY NOT affect the protein translated from the mRNA.
