Tyrosinase-related proteins TRP 1 and 2 control the quality of the melanin and, to a certain extent, suppress apoptosis. The TYR gene is a tyrosine-producing gene that is found on the 11th chromosome.
Option A represents the true genetic claim. -The TYR, TRP2, and TRP1 genes are located next to each other on a single chromosome and are organized into an operon.
What do the mammalian genes TYR, TRP2, and TRP1 do?
- The TYR, TRP 1 and TRP 2 are responsible for producing the coloration enzyme called melanin and the genes are located on the same chromosome.
- The fact that the mRNA transcription factors that regulate and control the genes' mRNA are the same means that the genes are operons.
- The MITF transcription factor, which is activated by the alpha-melanocyte hormone, controls the TYR, TRP 1 and 2 genes.
Hence, The correct option is A .

Full Question
Which of the following claims about the TYR, TRP2, and TRP1 mammalian genes is most likely to be accurate?
A-The TYR, TRP2, and TRP1 genes are located next to each other on a single chromosome and are organized into an operon.
B-The TYR, TRP2, and TRP1 genes may be located on different chromosomes but are activated by the same transcription factor.
C-The TYR, TRP2, and TRP1 genes are identical genes since they are activated by the same transcription factor.
D-The TYR, TRP2, and TRP1 genes may be located on different chromosomes but with identical operator sequences.
