The document describes the processes of transcription and translation. In transcription, RNA polymerase copies DNA in the nucleus to produce mRNA. The mRNA then exits the nucleus through nuclear pores and moves to the cytoplasm. In translation, mRNA binds to ribosomes in the cytoplasm where the genetic code is read and used to assemble amino acids into proteins.
129. Transcription
• In transcription RNA Polymerase splits a
section of DNA in half. mRNA copies the
genetic code. After the mRNA leaves the
nucleus through a nuclear pore. The mRNA
then goes to the cytoplasm/ribosome.
130. Translation
• In translation, mRNA becomes in contact with
the ribosomes. The ribosomes then split apart
into a big subunit and a small subunit. The
ribosomes reads the mRNA sequence. The
ribosomes then translates the sequence into
amino acids. The amino acids are connected
by a peptide bond, which make a protein.
