write the function of
I) cry IAc gene
ii) RNA interference
Answers
Explanation:
Cry1Ac is a mucosal adjuvant (an immune-response enhancer). It has been used in research to develop a vaccine against the amoeba Naegleria fowleri. This amoeba can invade and attack the human nervous system and brain, causing primary amoebic meningoencephalitis, which is nearly always fatal.
RNA interference has an important role in defending cells against parasitic nucleotide sequences – viruses and transposons. It also influences development. ... Each siRNA is unwound into two single-stranded RNAs (ssRNAs), the passenger strand and the guide strand.
Answer:
cryl AC gene:a) It produces inactive pro-toxin in the host cell produces proteins to control cotton bollworms. (b) It produces dsRNA which silences host m-RNA/cellular defense mechanism/prevents infestation by nematodes.
2) RNA interference:
The main biological function of RNAi is regulation of gene activity of cells at the post-transcriptional level (PTGS) either by the inhibition of translation of mRNA or by direct degradation of the mRNA.
