DNA Sequences That Do Not Code for Proteins

Question

DNA sequences that do not code for proteins
A) regulate gene expression.
B) transcribe mRNA, tRNA, and rRNA.
C) are structural, with repeated and translocated sections.
D) All of the answer choices are correct.
E) nonfunctional in the case of pseudogenes.

Accepted Answer

DNA sequences that do not code for proteins can have various functions including regulating gene expression, transcribing RNA molecules such as mRNA, tRNA, and rRNA, and being structural components of the genome with repeated and translocated sections. Pseudogenes, which are also non-coding, were once considered nonfunctional but are now recognized to have potential regulatory roles.
