Answer:
RNA interference
Explanation:
Interference RNA is a mechanism of post-transcriptional silencing of specific genes, so that small RNA molecules complementary to an mRNA lead to its degradation, thus preventing its translation into proteins.
Gene silencing by interfering RNA is induced by small double stranded RNA molecules of 21 to 27 nucleotides called siRNA. These siRNAs undergo a series of processes in the cell as a result of which their double stranded RNA unfolds in a sense strand and an antisense strand. The antisense strand binds to the mRNA chain specifically for base complementarity, causing the resulting complex to be recognized by cellular and degraded mechanisms. Each siRNA is highly specific for the target nucleotide sequence to which it degrades. This phenomenon of gene interference occurs naturally in the body, being involved in the development and defense against viruses.

Answer:
Melanin is responsible for black colour of hair.
Explanation:
Hair is black in colour because it is determined by the amount of a pigment present in hair is called melanin. If eumelanin which is a type of melanin, present in hair, it gives people black or brown hair. If the receptor is not activated or is blocked in the hair, then melanocytes make pheomelanin instead of eumelanin and then the black or brown hair colour did not occurs so we can conclude that melanin is responsible for black colour of hair.
