This article begins a new series about gene technologies. Many gene technologies, especially recombinant DNA technologies, begin with the need to isolate or make DNA fragments. We will look at three different ways that this can be achieved. Restriction enzymes This method allows DNA fragments to be "cut out" of existing DNA. Restriction enzymes, sometimes...

RNA – Biological Molecules Ep 2
Most people have heard of DNA, but ribonucleic acid (RNA) is its lesser known cousin. They have many similar features, but quite different functions. There are different types of RNA, the three main types being messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). If you have been following the cell organelle series, you … Read more
