Unformatted text preview: phate group nitrogenous base Uracil vs. Thymine in DNA RNA molecule is a single strand ribose sugar for each gene, only one of the two DNA strands is transcribed a real gene can real gene can contain thousands of nucleotides... mRNA contains the triplet code methionine lysine phenylalanine stop production a real protein can contain (at least) hundreds of AA’s of AA’s from which the sequence of amino acids is determined three types of RNA play different roles in protein synthesis messenger RNA (mRNA) – template strand RNA containing the code for amino acid sequence transfer RNA (tRNA) – carries the incoming amino acids to the mRNA (which is in turn held in place between large small subunits of the ribosome) between large & small subunits of the ribosome) ribosomal RNA (rRNA) – along with proteins, makes up the ribosome (site of protein synthesis) th initiation elongation termination for each molecule of RNA only one of RNA, only one DNA strand is transcribed (the template strand template strand) but which one varies according to the gene RNA polymerase binds to promoter...
