Answer:
a, b, c, e
Explanation:
- since mutations are random, they could both harm or benefit or have no effect on the organism (depends on where in the DNA is mutated, on the type of mutation that occurs, on whether the mutation is fixed, etc.)
- the binding between codons and anticodons are always as follows:
- A on mRNA binds to U on tRNA
- T on mRNA binds to A on tRNA
- G on mRNA binds to C on tRNA and vice versa
Mutagens are substances that damage DNA and can cause permanent changes in the DNA sequence, depending on the ability of the organism to fix the mess.
Mutagen's effect:
Deoxynucleoside triphosphates (dNTPs), which are utilized by DNA polymerases to duplicate DNA, can also be damaged by DNA-damaging agents.
- A mutagen could harm the organism by disrupting gene function.
- A mutagen may alter gene function to the organism's benefit.
- A mutagen can alter codon-anticodon binding.
Therefore, the final answer is "Option A, B, and D".
