Alternative splicing is the process of gene expression. It results in a single gene being able to produce multiple functional proteins. mRNA splicing includes certain exons and excludes others. This produces different mRNA strands with different base sequences, which then translates to different polypeptide chains with different codon sequences. Different polypeptide chains will then go through processing to become different proteins.
Hope this helps! :)
The correct option is OSMOSIS THROUGH A SEMI PERMEABLE MEMBRANE.
Osmosis is defined as the process by which molecules of a solvent [water] are transported through a semi permeable membrane from the region of a lower solute concentration to that of higher solute concentration. The membrane is said to be semi permeable because it allows the water molecules to pass through but does not allow the salt molecules to pass.<span />
