Under appropriate conditions, a recombinant DNA molecule can enter a cell and replicate there, either autonomously or after it has become integrated into a cellular chromosome. The natural process of breaking and rejoining DNA strands to produce new combinations of genes and, thus, generate genetic variation. Gene crossover during meiosis. Regulatory regions or sequences A DNA base sequence that controls gene expression. Remission Disappearance of the signs and symptoms of cancer.
Remission can be temporary or permanent.
The length of a nucleotide sequence that is repeated in a tandem cluster. Reproductive cells Egg and sperm cells. Each mature reproductive cell carries a single set of 23 chromosomes. Resolution Degree of molecular detail on a physical map of DNA, ranging from low to high. Restriction enzymes Enzymes that can cut strands of DNA at specific base sequences.
