DNA and Enzymes

Have you ever asked yourself why my eyes are the problem of this color? Or questions about why we are looking at us. All of our functions are summarized in our genetics. These genetics are the characteristics of families inherited through our strain. It all comes down to being regarded as our basic part, the DNA of ours. Deoxyribonucleic acid is the actual name of DNA. We have heard about DNA for years, but you really know about it. What is made of DNA In this article, I will explain this mini miracle called DNA.

I visited a collaborator Dr. David Hira on 10 / 22-10 / 26 of the week last week and started a project to study a kind of enzyme called MutY DNA repair enzyme. DNA is damaged. In many cases, the DNA repair enzyme finds the injured site and resolves the problem before it causes mutation or disease. The MutY enzyme detects and removes paired adenine (A) bases with guanine (OG) in damaged form. If MutY does not work well, our DNA may accumulate G: C → T: A mutation. If these mutations are included in tumor suppressor or oncogene genes, it can cause cancer especially in the colon. Sheila and I published a paper on MutY's system and mechanism in 2016. This is probably the most important document I have ever written, but scientists in this area are hard to understand. Our project is working hard to provide evidence of our idea to make things easier to explain and make people more understandable.

Step 1: The DNA extracted from the organism having the gene of interest is cut into gene fragment by restriction enzyme. These enzymes read the nucleotide sequence of DNA and recognize specific sequences. The enzyme then cleaves the DNA sequence by breaking the bond between the nucleotides in the DNA strand. Step 4: The recombinant plasmid is then transferred to the bacteria using electroporation or heat shock. Electroporation destroys bacterial cell walls and uses a small electrical pulse to create small holes. The plasmid is small enough to enter the cell through the well. Thermal shock works in the same way. But instead of using electricity to pierce bacteria, it is done by changing the temperature between hot and cold places.

Recombinant DNA allows scientists to isolate DNA, transport it to other organisms and study the role of DNA in new objects. This is done by cutting the DNA into fragments using enzymes. The enzyme used is called restriction enzyme, which is an enzyme that selectively recognizes and degrades foreign DNA. Selected fragments of truncated DNA are then placed into a vector to carry exogenous DNA sequences from one host cell to another. A small circular DNA molecule found in bacteria is called a plasmid and is a common carrier of this technology. (3) Plasmids are usually replicated independently of chromosomal replication and are very suitable for rapid replication of the desired DNA. Once the DNA has entered the plasmid, it can be put into the creature (2)
