- A form of programmed cell death that generally benefits the organism.
- The structure of DNA, in which two long strands of covalently bonded nucleotidesare held together by hydrogen bonds and
twisted into a spiral coil.
3 True/False Questions
DNA replication → The duplication, or copying, of a DNA molecule. DNA replication begins when the hydrogen bonds connecting the two strands of DNA are broken, causing the strands to unwind and separate. Each strand is then used as a template for the construction of a new strand of DNA.
complementary strand → A strand of DNA whose sequence of bases can pair (according to base-pairing rules) with the sequence of bases found in a focal DNA strand.
base pair → A pair of complementary nitrogenous bases that have formed hydrogen bonds with each other.
