What is produced inside the
nucleus during transcription that
makes it possible to move genetic
information outside the nucleus?
A. mRNA transcript
B. proteins
C. DNA
During transcription, the DNA sequence is copied into a messenger RNA (mRNA) molecule by RNA polymerase. This mRNA transcript carries the genetic information from the nucleus to the cytoplasm, where it can be used to direct the synthesis of proteins. The mRNA molecule is able to move outside the nucleus because it is small enough to pass through the nuclear pores. Once in the cytoplasm, the mRNA is translated by ribosomes to produce proteins.
