Most eukaryotic rna consists of coding regions, called and noncoding regions, called a. codons; spliceons b. introns; codons c. exons; introns d. introns; exons e. spliceons; codons

exons; introns.

Explanation:

The eukaryotic mRNA consists of exons and introns. The eukaryotic mRNA undergoes the process of splicing in which the introns are removed from the RNA molecule.

The exons are the coding regions of RNA that codes for the specific protein. The non coding regions of the RNA are known are known as introns that are removed from the RNA.

Thus, the correct answer is option (c).

enzyme speed up the reactions

i would go with b

cytokinesis occurs after telophase so that eliminates d

and the entire reason for cytokinesis is for cellular reproduction
