A number of forces can cause gene mutations, such as smoking, radiation, viruses, cancer-causing chemicals (carcinogens), obesity, hormones, chronic inflammation and a lack of exercise.
Answer:
The codons that code for LEUCINE amino acid are:
1. UUA
2. UUG
3. CUU
4. CUC
5. CUA
6. CUG
Explanation:
A CODON is a group of three nucleotides in the mRNA molecule that specifies a particular amino acid. It represents a trio combination of nucleotides (A, G, C, U). There are about 64 possible codons formed from four nucleotides used in a combination of three's i.e 4³ = 64. All the codons collectively form the GENETIC CODE, which is used by all known living organisms.
However, since there are only 20 amino acids in nature and 64 possible codons, more than one codon encodes an amino acid. This means that the genetic code is DEGENERATE or REDUNDANT. Hence, in this case involving the amino acid: LEUCINE, the six (6) codons that specify it (depicted in the attached genetic code) are as follows:
- UUA
- UUG
- CUU
- CUC
- CUA
- CUG

I dont see any options. Biotic factors are living factors, abiotic are non-living.
