Below is the ORIGINAL stretch of DNA, followed by DNA which has a MUTATION. Will this mutation likely have a bad consequence for the organism? Why?



Original: GCU ACC AGG

MUTATED: GCU ACT AGG

Respuesta :

No it will not. Since the mutation is towards the end of the codon, it is very likely that it would not change the amino acid at all.

This mutation likely have a bad consequence for the organism - No, because the mutation will not code for a different amino acid.

Amino acid sequences are formed by the translation and transcription from DNA sequence to mRNA and finally amino acid sequences.

  • Differences in amino acids chains can lead to differences in a protein (in shape and function).
  • the protein may not be functional if the amino acid sequence is changed.
  • It could lead to positive, neutral, or negative changes.
  • In the given case the change in mutated from the original is ACC to ACT
  • Both ACC to ACT codes for glutamic acid.

Thus, this mutation will not change the amino acid so the answer will be No.
