Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following involves using an RNA/protein complex to remove introns and connect exons in the RNA transcript?
A
Proteosome digestion
B
Histone acetylation
C
DNA methylation
D
alternative spicing
Explanation: 

Detailed explanation-1: -The third big RNA processing event that happens in your cells is RNA splicing. In RNA splicing, specific parts of the pre-mRNA, called introns are recognized and removed by a protein-and-RNA complex called the spliceosome.

Detailed explanation-2: -Pre-mRNA splicing is an essential step in gene expression that removes intron sequences efficiently and accurately to produce a mature mRNA for translation. It is the large and dynamic RNA-protein complex called the spliceosome that catalyzes intron removal.

Detailed explanation-3: -RNA splicing is a process in molecular biology where a newly-made precursor messenger RNA (pre-mRNA) transcript is transformed into a mature messenger RNA (mRNA). It works by removing all the introns (non-coding regions of RNA) and splicing back together exons (coding regions).

Detailed explanation-4: -Splicing is the process of removal of intron sequences and joining the exon sequences.
