What does recombining mean?
“Recombining” most commonly refers to the process of exchanging or rearranging genetic material. During recombination, sections of DNA are exchanged between chromosomes, producing new combinations of genetic information and contributing to genetic variation. The term can also mean combining or joining something again after it has been separated. In scientific writing, “recombining” often appears before words such as “DNA,” “genetic material,” and “chromosomes,” where it identifies a process rather than a completed result. For example, “recombining DNA” refers to the act or mechanism of creating new genetic combinations. Outside biology, the word is less common and retains the straightforward meaning of combining again, although its genetic associations make it especially useful in discussions of inheritance, evolution, biotechnology, and molecular biology.
Relating to or involving the exchange or rearrangement of genetic material.
"Recombining DNA occurs during meiosis."
This is the dominant technical sense, especially in biology and genetics.
Combining or joining again, especially by exchanging or rearranging constituent parts.
"The researchers recombined fragments of DNA to create a new sequence."
This is the present participle of the verb “recombine.”
Without recombination, inherited traits would rarely be shuffled between chromosomes, giving us much less of the genetic variety that shapes life.

Etymology of recombining
The word is formed from the prefix re-, meaning “again,” and combine, from Latin combīnāre, “to join together,” with the suffix -ing. The underlying Latin root com- means “together,” while bīnus refers to two. Combination and combinatorial are later English developments from the same Latin foundation.

How recombining is actually used
In genetics, it is typically used as an attributive modifier before terms such as DNA, genetic material, or chromosome. As a verb form, it describes the act of combining materials again.
Easily confused with recombining
A recombinant is an organism, chromosome, or DNA molecule produced through recombination, whereas recombining describes the process or an activity involved in recombination.
