Surname Lecturer Institution The Price of Silent Mutations Summary of the Article “Price of Silent Mutations” By Chamary, J.V. and Hurst Laurence Silent mutation can be described as an alteration of single nucleotide DNA which lies in the protein-coding region of a gene and which has no effect on the amino acid sequences coded for by the gene. For a very long time scientists believed that these types of mutations could not have an impact on a person since they do not affect the actual protein

Introduction Wheat (Triticum aestivum) is the most important and considered cereal crop for major part of global population. In Pakistan, wheat is most important crop of agricultural economy. It is grown each year on 8.3 million hectares that is 36% of total area cropped in Pakistan. It accounts for 40% of total value added of major crops. It is essential part of diet for population as it contributes 60% of daily diet of common masses in Pakistan. Average per capita consumption is around 125kg and

individuals cannot be easily applied to organisms that reproduce only or mainly asexually. Genes are what code for the traits of an organism, and the offspring inherits at least some of the genes from the parent. Genes are the portions of an organism's DNA that carry the code responsible for building that organism in a very specific way. From generation to generation, molecular mechanisms reshuffle, and alter genes in a way that produces genetic variation. Without genetic variation, the basic mechanisms

Crystallography and DNA Rosalind Franklin, the woman who contributed to scientist of the future understanding DNA structure. Scientist such as James Watson, Francis Crick, and Maurice Wilkins benefited greatly from her findings. They received a Nobel Prize based off of her findings. Rosalind was also an X-ray crystallographer. X-ray crystallography is used for looking at atomic and molecular structures of crystal. This work contributed to her discovering the structure of DNA. Franklin was born

and archaea. Viruses depend on the cellular system of their host for reproduction. Viruses have three main parts, which are nucleic acid, protein coat and lipid membrane. Nucleic acid is the core of a virion, which holds all the genetic information (DNA and RNA) and helps it multiply. The protein coat or capsid protects the virus by covering it and the capsid is covered by a envelope called lipid membrane. Not all viruses have the capsid and the ones that do not have the capsid known as naked viruses

theory was correct and laid the foundation for many other scientific studies to eventually lead to significant advancements in genetic study. In the 1960’s scientists exposed the genetic codes which led to decades of discovery to include genetic maps, DNA and RNA sequences, and multiple data strands. Gene therapy was introduced in 1990 with a clinical trial study on a 4 year old little girl suffering from adenosine deaminase deficiency (ADA); which is a severe combined immune deficiency brought on by

DNA is a large and complex molecule made up of a sugar phosphate backbone which consists of deoxyribose sugar bonded with phosphate groups. Then branching off the sugar phosphate backbone are complimentary nitrogenous base pairs which are Adenine, Thymine, Guanine and Cytosine. Transcription happens in the nucleus, where the double helix ‘unzips’ allowing mRNA to
