What is RNA interference in simple terms?
RNAi is short for “RNA interference” and it refers to a phenomenon where small pieces of RNA can shut down protein translation by binding to the messenger RNAs that code for those proteins. RNA interference is a natural process with a role in the regulation of protein synthesis and in immunity.
What is the RNA interference quizlet?
What is RNA interference? Down-regulation of gene expression by small RNA molecules, which inhibit translation or cause degradation of target mRNAs.
What is RNA interference in biotechnology?
RNA interference (RNAi) is a method of blocking gene function by inserting short sequences of ribonucleic acid (RNA) that match part of the target gene’s sequence, thus no proteins are produced.
What is RNA interference A level biology?
RNA interference (RNAi) is a form of post-translational modification which occurs in the cytoplasm. RNAi is sequence-specific silencing of gene expression and therefore can be very precise in silencing certain genes.
What is RNA interference PDF?
RNA interference (RNAi) is an evolutionary conserved mechanism which provides protection against invading viral particles or retrotrasposons and suppresses unnecessary expression of certain genes. Molecules like Dicer and RNA Induced Silencing Complex (RISC) are central to RNAi machinery.
What does RNAi stand for?
Introduction. RNAi stands for ‘RNA interference’, which is the silencing of gene expression by the administration of double-stranded RNA (dsRNA). Endogenous RNAi seems to be a primitive sort of immune system, the aim of which is to defend genomes against molecular parasites such as viruses and transposons.
What is a transcription factor A level biology?
A transcription factor is a protein that controls the transcription of genes by binding to a specific region of DNA. They ensure that genes are being expressed in the correct cells, at the correct time and to the right level.
Where is RNA interference found?
RNAi is an RNA-dependent gene silencing process that is controlled by RISC and is initiated by short double-stranded RNA molecules in a cell’s cytoplasm, where they interact with the catalytic RISC component argonaute.
What is gene silencing Upsc?
UPSC Exam Preparation: Topic of the Day – RNA Interference and Antisense Technology. RNAi is a gene silencing technology that inhibits protein synthesis in target cells using double-stranded RNA. Same result is achieved by Antisense technology through single-stranded RNA.
