Question

After an RNA molecule is transcribed from a eukaryotic gene, what is removed and what is spliced together to produce an mRNA molecule with a continuous coding sequence?a) operators; promoters. b) exons; introns. c) silencers; enhancers.

d) introns; exons. e) promoters; operators.

Answer 1

Answer:d)introns; exons

Explanation:Introns are the non-coding portion of the DNA. They do not code for a gene that can be expressed hence the need for them to be removed from the coding genes(Exons). The exons are then joined together after the introns have been removed to create a sequence of amino acids.
