Biology: recombinant DNA vs recombinant chromosomes
Tutoring biology, clarifying terms is sometimes necessary. The tutor distinguishes between recombinant DNA and recombinant chromosomes.
Recombinant DNA contains sequences from more than one source organism. It can refer to DNA produced by splicing together samples from different species. (See my post here.)
Regarding DNA, “recombination” doesn’t necessarily refer to production of recombinant DNA. During meiosis, recombination happens with “crossing over,” when homologous chromosomes swap their alleles of corresponding genes. The resulting chromosomes might be referred to as recombinant chromosomes. However, the DNA involved all comes from the same source, so the result isn’t recombinant DNA.
