Answer: c. are spliced out of the message.
Explanation: Intron are non-coding portion of the DNA sequence. They do not code for any specific amino acid and are spliced or removed before splicing.
Exons are DNA sequence that code for specific amino acid they are usually left after introns are removed and are joined together before translation into amino acid sequence. Intron splicing can lead to splicing some exons which can lead to formation of an entirely new amino acid or protein.
Spliceosome are enzymes for splicing introns.
I may be wrong but I think it’s the second one. They speed up reactions, and there’s a certain enzyme for a certain reaction.
In the nucleus of the cell, there are chromosomes that contain genetic material
This is possible by having different stem cells for different types of cells which then have different genes activated to make cells different
