D)transcriptons
E)poly-A tails

Question

Quizplus · Accepted Answer

Intervening, untranslated nucleotide sequences are called introns. Anticodons are sequences of nucleotides in tRNA that pair with codons in mRNA to specify amino acids during protein synthesis. Exons are the coding regions of a gene that are expressed as proteins. Transcription is the process of making RNA from DNA. Poly-A tails are stretches of adenine nucleotides added to the 3' end of mRNA molecules.
