Document Summary
Embryos genomes will develop in response to environmental queues in response to their surroundings to assure their survival. Induced pluripotent cells can be engineered from adult cells. A nucleotide composed of: a phosphate group po4, 5 carbon sugar (2-deoxyribose) 3: one of four cyclic nitrogenous bases. Dna is double stranded and the strands are antiparallel. 3 lines with 5 and 5 lines with 3 . Held together by hydrogen bonds between bases on opposing strands and hydrophobic interactions between adjacent stacked bases. Adenine base pairs with thymine (2 hydrogen bonds) and cytosine base pairs with guanine (3 hydrogen bonds; more stable) Higher g-c content dna molecule is more stable; harder to break down. 5 end has a free phosphate group. 3 end has a free hydroxyl group. Most common form of dna is called b-dna. Two grooves of different width: the major groove and minor groove. Z-dna left handed helix, 12 base pairs per turn.
