Answer:
genetic drift
Explanation:
Genetic drift is an evolutionary force that requires the presence of a small population. It is a random process that fixes one or other alleles randomly in the gene pool of a population. Genetic drift does not take account of survival fitness imparted by alleles to the individuals. Since random and chance events such as the death of all the individuals having a certain allele in a population affect the small population more intensely, genetic drift works on small populations only.
Answer:
As a result of a change in the sequence of nucleotides in a strand of DNA (Deoxyribonucleic acid), the amino acids also change in the final protein which leads to protein malfunction.
Explanation:
As a result of a change in the sequence of nucleotides in a strand of DNA (Deoxyribonucleic acid), the amino acids also change in the final protein which leads to protein malfunction. If insulin does not work correctly, it may not be able to bind to the insulin receptor.
DNA contains genetic information. It has a double helix structure.
I believe it would be Bone Tissue and Connective Tissue
Answer:
