The correct answer is: b. the removal of introns and alternative splicing of exons
Post-transcriptional regulation includes processes of regulation between transcription and translation such as RNA splicing, capping, addition of poly-A tail, RNA editing.
RNA splicing represents the process of RNA processing in which newly synthesized pre-mRNA transcript is converted into a mature mRNA. This process occurs only in eukaryotic organism and includes the removal of introns and joining together the exons. RNA splicing might occur during or immediately after transcription and it is performed by spliceosome (complex of small nuclear ribonucleo proteins).
Alternative splicing is a regulated process in which a single gene can code for multiple proteins because particular exons of a gene may be included within or excluded from the final mRNA.

Good luck and have a nice Benevolentpuppy day! :D
<h3><u>Answer;</u></h3>
The above statement is <u>false</u>
<h3><u>Explanation</u>;</h3>
- Rocks have different porosity and permeability characteristics, which means that water does not move around the same way in all rocks below ground.
- Permeability greater than 250 mD are considered very good, while permeability less than 1 mD are considered poor.
- Low porosity normally results in low permeability, but high porosity does not necessarily imply high permeability. It is possible to have a highly porous rock with little or no interconnections between pores.
