What are Transposons?
The genomes of living organisms are full of useful genes that govern traits such as hair color and behavior. But a large part of genomes are made up of DNA sequences that do not code for any traits. A closer look reveals the presence of some interesting elements, like the mobile transposons.

How the Genetics of Cows Affect Cheese Production
Geneticists have found that a specific protein within the DNA of cows has a major effect on the quality of the cheese. This is combined with additional research into microbes that turn milk sugars into lactic acid and allows the industry to continue expanding.

Morphs and Genetic Mutations
Genetic mutations are permanent changes in DNA. They can be acquired during an individual's lifetime or inherited from a parent. Silent, nonsense, and missense are just some of the different types of mutations. When genetic errors are classified by their behaviours they are called morphs.

Genetic Mutations and the Speed of Evolution
For higher animals the rate of evolutionary change chugs along at a snail's pace, at least to the naked eye. But under the bonnet, the rate of molecular evolution can zip along at quite a speed.

What is Antigenic Drift?
"Prevention is better than cure," they say, but prevention of diseases is not a problem that can be tackled easily. Influenza is a common problem in several regions of the world and tackling the problem is difficult. A significant factor is antigenic drift.

DNA Replication Errors
DNA replication errors that are overlooked during proofreading or fail to be repaired can result in mutations. Knowledge of the role of DNA polymerase and various additional enzymes involved in the process of DNA replication is important to understand how genetic mutations occur.
