WebAboutTranscript. Genetic recombination is a process that occurs during meiosis, which is the type of cell division that produces gametes. During this process, homologous chromosomes pair up and form a unit called a tetrad. The chromosomes can then cross over and exchange genetic material, which results in new combinations of alleles.

WebDNA ( deoxyribonucleic acid) is the genetic material of living organisms. In humans, DNA is found in almost all the cells of the body and provides the instructions they need to grow, function, and respond to their environment. When a cell in the body divides, it will pass on a copy of its DNA to each of its daughter cells. dr strange new trailer 3 WebThese DNA sequences recruit an array of telomere-specific DNA-binding proteins that catalyze the formation of a t-loop.
