Document Summary
Loose bundle of chromosomes in the form of a nucleoid, uncontained within the cell. Vertical gene transmission makes up most of their evolution. Vertical gene transmission makes up much of their evolution; however, there have been major. Dna associates with histones (proteins) to make chromatin. Complementary generally pair with the same nucleotide bases. Fidelity are inheritable from one generation to the next. Stability with too much change mutations occur (good or bad) Sophistically replicated and has the potential to self-replicate. Dna is constructed of a linear macromolecular polymer (deoxyribonucleotides) In general, a phosphate group, pentose sugar, and nitrogenous base make up a nucleotide structure. Dna contains an h at the 2" carbon of pentose sugar. Nucleotide bases attach via a n-glycosidic bond at the 1" carbon. Attaches to the 9th position on purines and 1st on pyrimidines. They can be labelled n, 2(carbon), n, 4(carbon) Thymine has an extra carbon group on the 5th position when compared to uracil.
