February 14, 2007 [ BLOCK C: BIOLOGY DUSTIN LEE 1. The nucleic acid made during transcription is messenger RNA. 2. Internal noncoding regions are called introns. These introns are removed before the RNA leaves the nucleus. The parts of a gene that remain in the mRNA and translated are called exons. 3. mRNA transcribes from a DNA template and is sent out of the nucleus to tell proteins what to do. tRNA translates the three-letter codons of mRNA to the amino acids that

Unformatted text preview: make up proteins. rRNA is one of the subunits of a ribosome. 4. It starts when the mRNA transcripts the DNA as a template. Then, the mRNA goes out of the nucleus and specifies the sequence of amino acids in a polypeptide built with the assistance of tRNA and rRNA of a ribosome. In the end, the proteins that form from the polypeptides determine the appearance and functioning of the cell and of the whole organism....
