Gene cloning occurs when a specific gene from a strand of DNA has been extracted and copied from an organism. Nearly any tissue source can be used for cloning, as long as there is not widespread degradation. DNA can also be extracted from RNA using a process called reverse transcription.Know More
Genes are made from DNA and contain the basic building blocks of heredity. When a gene is cloned, an exact replica is produced. The process requires a variety of biotechnical techniques.
A basic explanation of the process of cloning a gene:
DNA, or deoxyribonucleic acid, is used in the human body in order for an organism to reproduce, develop and survive as well as in science for genetic engineering, forensics, bioinformatics, evolutionary history and information storage. A human's DNA code contains about 3 billion bases and 20,000 genes in 23 pairs of chromosomes.Full Answer >
According to the National Center for Biotechnology Information, the primary role of DNA polymerases is to replicate the DNA of an organism, accurately and efficiently, during cell division. Additionally, polymerases play a vital role in proofreading the genetic code for errors and fixing those that arise.Full Answer >
DNA sequencing is used to identify individual genes within the DNA of any organism. This information can be used to identify variants and mutations that cause diseases and disorders.Full Answer >
The genetic resources and recombination of the DNA of the parent or parents of an organism determine whether the organism is heterozygous or homozygous dominant. In many cases, an organism expresses a trait more strongly when it comes from homozygous dominant genes than from heterozygous genes for the same trait. Not all traits have gene options which are strongly dominant, and organisms can be homozygous recessive as well.Full Answer >
