Biology lecture notes: dna structure & replication (16) 16. 1: how does dna replicate, deoxyribonucleic acid (dna), molecule forms the genetic material of all living organisms. Through dna the information required to sustain life is passed: u(cid:374)dersta(cid:374)di(cid:374)g ho(cid:449) dna repli(cid:272)ates (cid:272)o(cid:373)es fro(cid:373) u(cid:374)dersta(cid:374)di(cid:374)g it"s stru(cid:272)ture, dna structure: macromolecules-nucleic acids: Three parts (covalent bonds: base: carbon and nitrogen atoms, adenine, thymine, cytosine, guanine, pentose (5 carbon) sugar, phosphate group (s, dna structure: Leukocytes (pus filled bandages: nuclein (can be responsible for so many things in dna) Streptococcus pneumoniae (worked on pathology of pneumonia: r-strain/s-strain, rough vs. smooth.
