The Correct Answer is A
A. An intervening sequence that does not encode for proteins:
Introns are non-coding sequences within a gene that are removed during RNA splicing before translation.
B. The portion of the transcript that encodes for protein:
This describes an exon, not an intron.
C. A person with a recessive allele that the dominant allele silences:
This describes a carrier in genetics, not an intron.

This describes an allele, not an intron.

Explanation
A. Having greater than 50 moles and green or blue eyes:
Risk factors for melanoma include having many moles, fair skin, light-colored eyes, and history of sunburns.
B. Intermittent claudication and diabetes:
These are vascular and metabolic problems, not related to melanoma risk.
C. Black or brown hair and darker pigmented skin:
Darker skin provides some natural protection against UV radiation, reducing melanoma risk (although melanoma can still occur).
D. Younger than 18 years of age and obesity:
Age under 18 and obesity are not primary risk factors for melanoma. Cumulative sun exposure and genetic predisposition are much more relevant.
