BIOL 1001 Lecture Notes - Lecture 12: Ribosomal Rna, Deoxyribose, Ribose
Document Summary
Gene expression and regulation part 1 of 2. Genetic information is _transcribed into rna and transalted into proteins_ 12. 2: dna is transcribed into rna, rna is translated into protein. The message is carried by _messenger rna____(ribonucleic acid) The message must be carried from the dna in the nucleus to the ribosomes in the cytoplasm. Rna uses the base _uracil___ (u) instead of _thymine____ (t) Three types of rna aid in protein synthesis: _messenger rna_ (mrna, _ribosomal rna_ (rrna, _transfer rna___ (trna, comparing nucleic acids: dna and rna table 12. 1. Major types of rna (ribonucleic acid): mrna (messenger) fig. 12. 1 carries the code for protein synthesis from dna to ribosomes__ Groups of three bases called _codons_ specify which amino acid will be added to a polypeptide chain during _translation_major types of rna (ribonucleic acid): rrna (ribosomal) Ribosomes are the site of protein synthesis_during translation. Made of one large and one small _subunit_ fig. Major types of rna (ribonucleic acid): trna (transfer)
