Unformatted text preview: 5. Two new DNA molecules formed Each copy has 1 old strand and one new strand -> semi conservative 1/3 DNA Deoxyribose sugar Thymine Double stranded Can replicate itself RNA Ribose sugar Uracil Single stranded Cannot replicate itself mRNA, A pairs with U DNA makes all 3 kinds of RNA DNA carries the master code for protein synthesis mRNA carries the genetic code from the nuclear DNA to the cytoplasmic ribosomes in long strands. mRNA, every 3 bases codes for one amino acid, 3 bases = codon Ribosomal (rRNA) is necessary for protein synthesis Transfer (tRNA) attaches to the proper amino acid (taxi in groups of 3 bases) Codons written in mRNA In RNA, A pairs with U, T pairs with A Ribosomes are where protein synthesis occurs are the binding sites for mRNA & tRNA are composed of rRNA & protein Protein sysnthesis Transcription DNA -> mRNA Inside nucleus Translation mRNA -> protein 2/3 Inside cytoplasm 3/3...
