How can large molecules be taken into cell
WebDNA cloning is the process of making multiple, identical copies of a particular piece of DNA. In a typical DNA cloning procedure, the gene or other DNA fragment of interest (perhaps a gene for a medically important human protein) is first inserted into a circular piece of DNA called a plasmid.The insertion is done using enzymes that “cut and paste” DNA, and it … WebDigestion is the process where the large molecules in the food that we eat are broken down into smaller ones that we can use for energy or as building blocks. This is done in the digestive system ...
