Answer:

RNA interference

Explanation:

The RNA interference (RNAi) pathway is a naturally occurring mechanism in which regulatory non-coding RNAs (ncRNAs) suppress gene expression by targeting messenger RNAs (mRNAs). The RNAi technique is used in molecular biology laboratories and biotechnology applications to reduce the expression of target genes by delivering small interfering RNA (siRNA) molecules targeting a gene of interest. These siRNAs are artificially synthesized to bind by complementarity to the target mRNAs, thereby they can be used for transient gene silencing. This technique does not require genetic modification of the cells, since RNAi can be achieved by direct exogenous delivery of siRNAs.

Which of the processes are coupled (i.e. LINKED) in prokaryotic organisms but uncoupled (i.e. UNLINKED) in eukaryotic organisms?
PilotLPTM [1.2K]

Answer:

Transcription & translation (Ans. A)

Explanation:

Prokaryotic organisms do not have membrane-bound organelles such as the nucleus, thus the process of transcription & translation occurs in the cytoplasm. Also because of the need for rapid life cycle, the mRNA molecules start to be made, & their ribosomes are ready to start making proteins more rapidly than Eukaryote, thus the process of the couple is quicker.

In eukaryotic organisms, transcription process start (happens) inside the nucleus of the cell and translation process can't start until the mRNA is transported out from the nucleus into the cytoplasm.

Why is it necessary for the pancreas to secrete a high ph (basic) solution into the small intestine?
storchak [24]
It is necessary for the pancreas to secrete a high pH solution into the intestine in order to neutralize the acidity of the processed food particles [chyme] that are passed into the intestine and to provide a suitable pH for the enzymes in the intestines that will act on the processed food particles.
