• DNA replication is a process in which DNA makes an exact copy of DNA
• chemical direction of replication is 5 five prime to 3 three prime
• in DNA replication nitrogenous base are complementary adenine always binds to thymine and forms two hydrogen bonds cytosine always binds to guanine and forms three hydrogen bonds
• DNA molecule polymer of nucleotides, nucleotide made of three components, phosphate functional group, a pentose ( deoxyribose for DNA, N base ( ATG or C)
• single strand of DNA has three nucleotides shown reads 5 TGC3 or you can also say that it reads 3 CGT5)
• DNA replication stages, 1- unwind double helix, 2 maintain serentation of the DNA strands, 3 synthesis of new strands, formation of two dsDNA molecules
• transcription synthesis of RNA from a DNA template three major RNA produced rRNA, tRNA, MRNA
• ribosomal RNA is a component of ribosomes involved in protein synthesis , transfer RNA is the carrier of amino acids
• messenger RNA dictates the amino acids sequence
• RNA molecule polymer of nucleotides
• nucleotide made of three components phosphate functional group, ribose for RNA, N base ( AUG or C)
• transcription stages 1. unwind double helix, 2. synthesis new RNA strand, 3. seperation of RNA from DNA double helix reforms
