Question | Answer |
---|---|
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 |
