Document Summary

A double stranded dna molecule in the nucleus unwinds a section itself that consists of a single gene. One of the strands coding for the gene exposes itself to the nucleoplasm. The enzyme, rna polymerase moves along the strand attaching the loose rna nucleotides to the dna, with a u and g c, until the whole gene is copied. The new rna, is now known as mrna. A start codon and a stop codon determine the length of the gene. The mrna strand exits the nucleus and enters the cytoplasm: translation: The mrna strand binds to a ribosome in the cytoplasm, with the start codon being aug(always) The ribosome moves along the mrna strand, to read" more of the bases trna molecules floating in the cytoplasm, which have anti-codons complementary to the codons of the mrna enter the ribosome. As the trna releases its amino acid to attach to the ribosome, it leaves to find another amino acid.
