Respuesta :
The TYR, TRP2, and TRP1 genes are located next to each other on a single chromosome and are organized into an operon is most likely to be accurate.
The option a is correct.
Explanation:
The genes for the Tyrosinase, TRP2 and TRP1 are located on the same chromosome and are operons. These are operons because they are controlled by same transcription factors on mRNA.
Tyrosinase enzyme is important for the synthesis of melanin, eye pigments and hair colour. The synthesis of all these is completed in three distinct reactions catalysed by TRP1, TRP2 and Tyr genes. These work as operon and the protein product is almost 40% similar of the three genes.
The amount of melanin production depends on tyrosinase enzyme activity of all the three genes.
The genetic regulation is done by operons.
TRP 1 and 2 are tyrosinase-related proteins regulates the melanin quality and also inhibits apoptosis at a certain level. Tyrosine producing genes located on the 11th chromosome is called the TYR gene.
The accurate claim about the genes is option a. The TYR, TRP2, and TRP1 genes are located next to each other on a single chromosome and are organized into an operon.
What are TYR, TRP2, and TRP1 mammalian gene:
- The TYR, TRP 1 and TRP 2 are responsible for producing the colouration enzyme called melanin and the genes are located on the same chromosome.
- The genes are operons as they are regulated and controlled by mRNA transcription factors which are the same for the genes.
- The TYR, TRP 1 and 2 genes are regulated by the MITF transcription factor which gets activated from the alpha-melanocyte hormone.
Therefore, option a is correct.
