Question

An organism is exposed to a mutagen, such as X-rays or ultraviolet light. What could be the effect of the mutagen on the organism? Select all of the answers that apply.
The mutagen may disrupt gene function to the harm of the organism.
B. The mutagen may change gene function in a way that benefits the organism.
C. The mutagen may change the genetic material of the cell from DNA to proteins.
D. The mutagen may change the binding between codons and anticodons.
E. The mutagen may have little or no observable effect on the organism.

Answer 1

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
