Answer:
Mutation is the source for new genetic variation: Genetic variation is brought about by random mutation. Without mutation, genetic variation cannot occur. Mutation is a change in the genetic code in DNA and can lead to a change in the protein that is coded for that segment of DNA.
Explanation:
Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

What ik tht thts what scientists figured out and thts all :)
Answer:
The template strand is the antisense strand or non-coding strand with polarity in the direction of 3' to 5' end which codes for the primary RNA molecule.
The template strand codes for the proteins through transcription and translation. The transcription creates a copy of the sense strand in the form of RNA as RNA polymerase binds the promoter and adds nucleotides in 3' to 5' direction.
The mRNA molecule formed as a result of transcription contains code in the form of codon or triplets of nitrogenous bases which are read by the ribosomes and specific amino acids are added to the growing polypeptide chain via tRNA molecule.
Thus, a template strand codes for amino acids.
