Definition

describes a biological product or living thing made by joining together genes from separate organisms in a laboratory — an approach often used to create medicines, vaccines, and research tools.

Example

Scientists use recombinant DNA technology to produce insulin for people with diabetes.

attributive: recombinant DNA

The lab created a recombinant vaccine by inserting a virus gene into yeast cells.

Common collocations
  • recombinant DNA
  • recombinant protein
  • recombinant vaccine
  • recombinant technology
  • recombinant cells
  • recombinant organism
Synonyms
  • genetically engineered

    broader term; all recombinant organisms are genetically engineered, but not all genetically engineered products are made by recombination

  • synthetic

    different method; synthetic DNA is built chemically from scratch, while recombinant DNA is assembled from natural material

  • modified

    much broader in meaning; can refer to any kind of change, not just at the genetic level

Antonyms
  • natural

    occurs in nature without human laboratory intervention

  • wild-type

    the naturally occurring genetic form of an organism, used in laboratory comparisons

Grammar Patterns

recombinant + noun

Usage Note

Almost always used before a noun it modifies — you will commonly see it in phrases such as recombinant DNA, recombinant protein, and recombinant vaccine. The term belongs to the vocabulary of molecular biology and biotechnology; outside of scientific writing, it is rarely encountered.

Common Mistakes

The supermarket sells recombinant vegetables.
The supermarket sells genetically modified vegetables.
recombinant describes a laboratory technique for joining DNA from different sources, not simply any modified crop.

Synonym discussion

Sense: adjective/1

Recombinant, genetically engineered, synthetic, and modified all describe human-made changes to living things, but at different levels of specificity. Recombinant refers specifically to the laboratory technique of cutting DNA from two or more different sources and joining them together — the result has genes that would never meet in nature. Genetically engineered is the broader umbrella: any direct manipulation of an organism's genome counts, including editing a single existing gene rather than importing foreign DNA. Synthetic goes further still: synthetic genes are built chemically from individual nucleotides, not taken from a natural organism. Modified is the most general term — it covers everything from selective breeding to CRISPR edits. Transgenic is a near-synonym of recombinant, but emphasises that the inserted DNA comes from a different species. In practice, a scientist might call a crop "transgenic" to highlight the cross-species origin or "recombinant" to highlight the DNA-joining method.

Etymology

LatinEnglish

Formed from the prefix re- ('again') and the verb combine, with the adjective suffix -ant. The term entered English in the mid-20th century as molecular biologists developed techniques to cut and splice DNA from different organisms, giving rise to the word recombination for the process and recombinant for the resulting material.
