Mutated codons code for what in silent mutations?

Biology
1 answer:
Marina86 [1]3 years ago
6 0

Answer:

Code for the same amino acid as the original codon

Explanation:

Mutation, which is any alteration in the nucleotide sequence of a gene, can occur when there is a replacement of base nucleotides. This is called SUBSTITUTION MUTATION. Substitution mutation can either lead to missense, nonsense or silent mutations.

As stated in this question, SILENT mutation is the one in which there is no change in the amino acid sequence after translation of the mutated mRNA. In other words, the mutation leads to an alteration of codon but the MUTATED CODONS CODE FOR THE SAME AMINO ACID as the original codon, hence, no effect on the protein produced or individual, in general.

Answer:

An example some organisms unconsciously drive the selection of others is DOMESTICATION in plants

Explanation:

In plant domestication, unconscious selection brought about by the fact that the plants concerned were taken from their original wild habitats and placed in new and very different human-made or human-managed environments.

The shift in the ecology led automatically to drastic changes in selection pressures. Numerous adaptations vital for survival in the wild environments lost their fitness under the new sets of conditions. New traits were automatically selected, resulting in the build-up of characteristic “domestication syndromes,” each fitting the specific agricultural environment provided by the farmer.

With this explanation, it can be established that the wild plants unconsciously drive the selection of domestic plants, through a change in habitat by farmer
