The Cell Cycle, DNA Replication, and Repair

摘要: Publisher Summary This chapter describes the cell cycle, DNA replication, and repair. The cycle is period during which duplicates its entire contents such that on subsequent division, each daughter contains all material originally present in parent at beginning of cycle. diploid human genome approximately 1010 base pairs distributed into 46 chromosomes. near-perfect replication these molecules effected confines nucleus time interval a few hours or less. ability to replicate lies complementary pair structure molecule. double-stranded molecule semiconservative, is, progeny one parental newly synthesized strand. accomplished by separation two strands synthesis new using separated strand as template. basic reaction nucleotide polymerization carried out polymerases.
