A recombinant DNA is artificially constructed DNA molecule with genes of interest that would not be present in the genome otherwise. It is a combination of a vector and a gene of interest. The recombinant DNA is inserted into bacteria E. coli, which, thanks to their reproductive potential, produce multiple copies of this recombinant DNA along with the chromosomal DNA. So, the gene for insulin is inserted int bacteria where is transcribed together with bacterial genes and the great amount of insulin is produced.
If we continue to increase greenhouse emissions, more of it will build up in the atmosphere, meaning more of the Sun's infrared radiation will be trapped via the Greenhouse Effect. This will cause the planet to warm.
