- A form of programmed cell death that generally benefits the organism.
- 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.
- The sequence, or order, in which the nitrogenous bases adenine (A), cytosine (C), guanine (G), and thymine (T) are arranged in a gene or a DNA fragment, or in an organism's genome.
3 True/False questions
mutagen → A form of programmed cell death that generally benefits the organism.
DNA polymerase → The key enzyme that cells use to replicate their DNA. In DNA technology, DNA polymerase is used in the polymerase chain reaction to make many copies of a gene or other DNA sequence.
mismatch error → A substance or energy source that alters DNA.
