activity‚ you learned how DNA encodes the instructions for creating proteins. You also learned about the basics of the process of protein synthesis. In this activity you will apply your knowledge of transcription and translation to decode a secret message as well as investigate the effect that various mutations have on protein production. You will then look specifically at the genetic mutation that causes sickle cell disease. Equipment Computer Laboratory journal DNA sequence Activity 3.2.2: mRNA
Premium DNA Gene
Many people believe that DNA was discovered in 1950 by Watson and Crick‚ but they are misguided‚ in fact it was discovered almost centuries before by a number of less known scientists. Genes were discovered to be heritable from parents by a humble pea grower by the name of Gregor Mendel in 1866. Since then we have discovered that DNA‚ also known as deoxyribonucleic acid‚ is the carrier of genes‚ traits that pass down from generation to generation.The reality is that the credit didn’t go to everyone

nucleoid in prokaryotes. The nuclear body houses the chromosome in both prokaryotes and eukaryotes. Single in number and circular in shape‚ the chromosome in prokaryotes is made up of Deoxyribonucleic Acid (DNA) and proteins whilst in eukaryotes‚ it is usually more than two in number‚ and composed of DNA‚ histone and other proteins. In terms of ribosomes prokaryotes consist of 70S type‚ and the two subunits are 50S and 30S. Ribosome in eukaryotes is of 80S type‚ and the two comprising subunits are 60S

Eukaryotes have a nucleus with genetic information inside them and are more complex than prokaryotes which have free floating genetic information and no nucleus. 15. Nucleus has DNA Mitochondria- converts chemical energy into usable compounds Ribosomes- assembles proteins Chloroplast-converts sun’s energy into chemical energy and is only found in plants 16. Osmosis 17. ATP- stores and releases energy by breaking polypeptide

Proteins play an important role in the human body. The DNA molecule controls the synthesis of proteins. The DNA contains genes which are sequences of nucleotides and bases. Proteins are used for growth and repair. Proteins are made up of amino acids linked together by peptide bonds. Firstly ’amino acid synthesis ’ is the set of biochemical processes by which the various amino acids are produced from other compounds. The substrates for these processes are various compounds in the organism ’s diet

Introduction A mutator strain is one that lacks certain repair methods when a mistake is made during DNA replication. The strain of E. coli that was used in this lab‚ XL-1 Red Mutator‚ lacked three different repair methods used to correct mistake in DNA replication. If a mistake occurred‚ the E. coli would not be able to make repairs via DNA polymerase backtracking‚ mismatch repair‚ or oxo-dGTP hydrolysis. The E. coli will still be able to use the other ways to repair mistakes including SOS

My name is Erwin Chargaff and I discovered the structure of DNA. After reading Oswald Avery’s report‚ in 1944‚ about how genes were composed of DNA I become motivated to begin work on the chemistry of nucleic acids. I started researching with the belief that DNA from different species are different so I had to come up with an experiment to examine the DNA from different species. It was hard for me because I couldn’t get large amounts of DNA so it took awhile for my experimenting. After about 2 years

Mr. Jeffrey Goines was caught by the New York police officers spreading DNA liquid on the seats of the subway. Goines confessed to breaking the DNA drive and spreading its content in public. In addition‚ he confessed that he was paid by an animal rights organization and was spreading the organization’s message. While the practice of spreading DNA in the public is not directly harmful to health‚ medical and home security professionals are concerned with the possibility of this scenario. Mr. Goines
