Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.
The answer is true hope it helps
A codon is a sequence of three bases found on the messenger RNA (mRNA) molecule which is translated to produce an amino acid. Each amino acid is coded by one or more specific codons. If the codon is changed through a mutation, the amino acid produced may be different. However, in this case, the other codons that produce Leucine are:
UUA, UUG, CUU, CUC, CUA and CUG
So the code CUU could mutate to CUC, CUA or CUG and leucine would still be produced.
Astrology
Explanation:
A person studying the field of Astrology would not have her finds testable by others because most are descriptive and not experimental in nature.
Astrology is a pseudoscience claiming divination by the positions of the planets and sun and moon.
- It is simply the study of stars and their patterns.
- Most astrologers use positions of planetary bodies to predict future events and some topical matters.
- Astrology is not pure experimental science that can be tested using sophisticated instruments in the laboratory or in the field.
- Biology is the study of life and follows the scientific way of studying nature.
- Chemistry and physics are pure sciences that follows the scientific nature in their investigation.
