Crick felt " he " could use mutagenesis and genetic recombination phage to further delineate the nature of the genetic code.
32.
In collaboration with Jean Weigle, Meselson then applied the density gradient method to studies of genetic recombination in the bacteriophage Lambda.
33.
Even among true breeding organisms, some variation due to genetic recombination or to mutation can produce a few " off types ".
34.
Until this point, it had only been hypothesized that genetic recombination could occur during meiosis, although it had not been shown genetically.
35.
But genetic recombination ( chromosomal crossover ) mixes genes from non-sister chromatids from both parents during meiosis, thus muddling the ancestry path.
36.
Atypical genetic recombination during crossover when a sperm cell is developing can result in karyotypes that do not match their phenotypic expression.
37.
In some species, such as Arabidopsis thaliana and Oryza sativa, most TAGs are the result of unequal chromosomal crossover during genetic recombination.
38.
"' Recombination detection program "'( RDP ) is a computer program used to analyse nucleotide sequence data and identify evidence of genetic recombination.
39.
Both the non-crossover and crossover types of recombination function as processes for repairing DNA damage, particularly double-strand breaks ( see Genetic recombination ).
40.
The spread of antibacterial resistance often occurs through vertical transmission of mutations during growth and by genetic recombination of DNA by horizontal genetic exchange.
