Chapter 12 -rna:middleman,3 types,splicing DNA provides instructions for protein synthesis via RNA intermediaries (“middle-men”) DNA in eukaryotes is kept in the nucleus and cannot get out to the cytoplasm Protein synthesis occurs at ribosomes in the cytoplasm DNA information must be carried by an intermediary, ribonucleic acid (RNA) , from the nucleus to the cytoplasm RNA differs structurally from DNA in three ways RNA is single-stranded (not double like DNA) RNA has the sugar ribose rather than deoxyribose in its backbone RNA contains the nitrogenous base uracil (U) instead of thymine (T)

Unformatted text preview: So its 4 bases are A, U , C, G G still pairs with C, but in RNA, A pairs with U Mrna,trna, rrna rRNA and proteins form ribosomes – Ribosomes, the structures that carry out translation (synthesize proteins), are composed of rRNA and many different proteins – Each ribosome consists of two subunits—one small and one large—that contain various sites needed for protein synthesis tRNA carries amino acids to the ribosomes for addition to the growing protein mRNA carries the code for protein synthesis from DNA to the ribosomes...
