Vanity Fair. PCR allows us to increase the number of DNA molecules so that other tests, such as sequencing, can be performed with it.
News — Science and Environment. The chromosomes composed of these matching genes are called homologs. Learning Objectives By the end of this section, you will be able to: Explain the basic techniques used to manipulate genetic material Explain molecular and reproductive cloning.
A specialized division of chromosomes called meiosis occurs during the formation of the reproductive cells, or gametesof sexually reproducing organisms. Other oncogenes transform cells so that they grow in the absence of growth factors.
During DNA replication, each chromosome duplicates into two attached chromatids. The technology is similar to the technology that was used to produce Dolly, but the embryo is never implanted into a surrogate mother. Studies of viruses that transform cultured cells and thus lead to the loss of control of cell growth have provided insight into the mechanisms that drive the formation of tumours.
