Biology I-6

Genes particular sections of DNA molecules with the directions to build the proteins for cell structures and functions.
Heredity passing of traits from parent to offspring
nucleic acids: long chains of nucleotides, such as DNA or RNA, which carry genetic information
Complementary two strands of nucleotides match up according to the base pair rules (GCAT)
antiparallel strands of DNA run in opposite directions
double helix the shape of a DNA molecule which looks like a twisted ladder
hydrogen bonds weak bonds between polar molecules; hold the two strands of a DNA molecule together
deoxyribose: the five-carbon sugar in DNA nucleotides (has one less oxygen than ribose)
nitrogen base ring-shaped molecules attached to sugars of nucleotides that make them G,C, A, or T
