Here is a term paper on the structure of DNA in humans. DNA is a complex structure, made up of nucleic acids. These are information carriers, along with RNA the other nucleic acid. These two combine to create the guidance system for cells. As a result, they provide the knowledge to create specific proteins that define specific biological traits for [...]
This article provides an experiment on DNA. As early as 1848, Wilhelm Hofmeister, a German botanist, has observed that cell nuclei resolve themselves into small, rod-like bodies during mitosis. Later, these structures were found to absorb certain dyes and so came to be called chromosomes (colored bodies). In 1869, Friedrich Miescher, a Swiss physician, isolated a substance from cell nuclei [...]
The following points highlight the three methods to introduce alien DNA into host cell. The methods are:- 1. Microinjection 2. Electroporation 3. Shot-Gun/Gene Gun Method of DNA Introduction. Method # 1. Microinjection: DNA can also be stably introduced into tissue culture cells by its direct microinjection into the nuclei of the cells, using a glass micropipette that has been drawn [...]
