Genome editing using CRISPR/Cas 9 technology has progressed rapidly in recent times. Clustered regularly interspaced short palindromic repeats (CRISPRs) were first discovered in DNA from Escherichia coli in the late 1980’s. They remained an interest for nearly 20 years and were mainly studied for their…

Introduction The primary purpose of this experiment is to find the dominant and recessive allele of the Mung beans and the corn on the cob. After that, the focus shifts to the inheritance of single and double gene pairs from the parent genes. This experiment…

One of the ethical issues raised during this unit was based around knowing your genome. Many people believe that new DNA based companies such as 23andMe and FamilyTreeDNA, the availability of a person’s DNA will be easily available for everyone to see. This raises concerns…

Cancer is known to be a multi-step process that involves different stages like initiation, promotion, progression and metastasis. Chemical carcinogens including Arsenic, Chromium, Lead, Mercury, Chloroform, PAH (Poly aromatic hydrocarbon, THM (Trihalomethanes) elements can change any of these processes to induce their carcinogenic effects. Approximately…

ABSTRACT Two people decided to find out what types of bacteria is growing in campus. Soil was the choice of sample gathering. The bacteria was obtained and cultured to give rise to colonies which was then taken to determine its morphology as well as to…

Tobias et al. (2017) looked into the effects pressure has on the DNA deposited. They used polycarbonate boards that were soaked in 25% bleach for 20 minutes and rinsed with deionised water. The board was then UV-irradiated for 5 minutes on each side to remove…

What is DNA? DNA, properly named Deoxyribonucleic acid, is within all humans. DNA is a three-part system. The first part is deoxyribose sugar, which is where we get the beginning, deoxyribo. The second part is nucleic. The nucleic is the location of the DNA. Lastly,…

DNA is deoxyribonucleic acid, a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. History of DNA It is a common rumour that Francis Crick and James Watson first discovered the…

Nucleic acids-based drugs such as plasmid, antisense DNA, and siRNA can be incorporated into polymeric micelles through polyion complex formation between negatively charged nucleic acids and positively charged PEG-β-PAA copolymers. Polymeric micelles immensely enhance the stability of nucleic acids-based drugs under in vivo conditions, prompting…
