ANT E101 Lecture Notes - Lecture 7: Messenger Rna, Transfer Rna, Asparagine
Document Summary
Protein synthesis takes place outside of the nucleus. Dna has to be carried out of the nucleus to the ribosomes. Results in rna (single stranded, ribose sugar, uracil base) Dna splits in region of gene and attracts complementary nucleotides. Complementary messenger rna (mrna) strand is synthesized. This mrna will leave the nucleus and travel to the ribosome for protein synthesis. When the mrna binds to the ribosome, protein synthesis is initiated. As each codon in the mrna sequence is read, a trna brings the corresponding amino acid to the ribosome. Happens outside the nucleus, at the ribosome. Transfer rna (trna) molecules bind to the complementary mrna strand at the ribosome, bringing them amino acids specified by the mrna codon. As amino acids are brought to the ribosome, they bind together to form the amino acid chain of the synthesized protein. Dna template strand - ata gat cgc tta. Mrna sequence - uau cua gcg aau.
