Intervening Sequences That are Transcribed,but Not Translated into Protein Are

Question

Intervening sequences that are transcribed,but not translated into protein are called
A)exons.
B)introns.
C)spliceosomes.
D)transposons.
E)transcription factors.

Accepted Answer

Introns are intervening sequences that are transcribed from DNA to mRNA but are removed (spliced out) before translation into protein. Exons, on the other hand, are the coding sequences that are expressed and translated into protein. Spliceosomes are the molecular complexes that carry out the splicing process, but they are not the introns themselves. Transposons are DNA sequences that can move (transpose) from one location to another within the genome. Transcription factors are proteins that bind to DNA and regulate gene expression, but they are not the sequences themselves.
