Answer:
I had a long answer that I would have loved to share but I can't because brainly does not like the words using and there is no way around it, tried using every synonym on the internet... LOL sorry
Answer:
Genetic variation
Explanation:
Drift and natural selection are natural phenomena that occur when there exists genetic variation. In the first case (drift), the consequence will be the decrease in the genetic diversity, while natural selection will change the allele frequencies in order to favor adaptive genetic differentiation
A lot of DNA is structural and doesn't pertain to any genetics while it only takes a small change to change something big. DNA mainly uses 4 different chemicals to change itself, not giving a lot of variety. Most animals share around 98% of the same dna with each other. Humans share 50% of their DNA with a banana. Pretty much everything shares the same double helix design as well. So a lot of genetic code looks similar.
Answer:
Explanation:
DNA are molecules that store genetic information in all organisms.
RNA are molecules that will form proteins based on the instructions coming from DNA.
