As a population, organisms look different. Genetic variations and phenotypic differences are a direct result of the processes of transcription and translation at the molecular level. In the paragraphs that follow I will discuss how the processes at the molecular level influence traits that we see at the species level. A human has 23 chromosomes, each of these chromosomes are a housing unit for DNA. DNA, also known as deoxyribonucleic acid, is a simple molecule found in all living organisms. DNA…

The relationship between central dogma and a genetic code The vital sequence of different processes that transfers the genetic code from DNA via mRNA to finally form the functional product (finished proteins) together forms the central dogma of modern molecular biology. Thus, the genetic code is the basis of the central dogma of molecular biology. Central dogma is nothing but the flow of genetic information in all living cells including human cells from DNA to RNA to proteins. The central dogma…

Structure and function have always had a close relationship in biological, chemical and general terms. Often the functionality is dependent upon the structure, for example the villi on the epithelial cells increase the surface area and hence the rate of absorbance of molecules in to cells and the blood stream. DNAs function is highly specific to its structure as even the smallest change to this could cause a long term effect, or even death. Base sequence mutations, errors in replication and…

Gene editing has long been held out as a potential panacea for all human genetic disorders. Beyond human disease, it holds potential for producing disease free and larger plants and animals. Alternatively, resistance to herbicides can be edited into a plants genome or genes to increase drought tolerance. Furthermore, slight tweaks to the genome can produce crops that will be more desirable to consumers and thus enable their producers to earn more money. If the small change is only the removal of…

The DNA in living things is highly conserved. DNA has four bases that code for all differences in living things on Earth. Adenine, Cytosine, Guanine, and Thymine line up in a specific order and a group of three, or a codon, code for one of 20 amino acids found on Earth. The order of those amino acids determines what protein is made. Interestingly scientists have found that only four nitrogenous bases that…

In today’s technology, we can safely assume that GMOs can be produced and engineered in many different ways. There’s a leading multimillionaire genetic company called, Monsanto. Monsanto is an engineering company designed to alter and change organisms in their labs. Like for example, Monsanto would take a seed of an organism and alter its DNA in the way farmers would like it. Monsanto alters DNA and then instead of always farming their own seeds, they sell their DNA altered seeds also known as…

It was time to depart. The engines had been warmed up, the supplies were ready and the equipment had been installed and was ready to use. “Five, four, three, two, one, BLAST-Off” chanted Captain Xerox at headquarters, and with that our micro-V96 craft was propelled towards the cell membrane for the first leg of our journey to investigate the process of Protein Synthesis in a eukaryotic animal cell. The cell membrane is a delicate wall of phospholipid molecules, consisting of hydrophilic heads…

other healthy cells to get through causing blood clots and restricting oxygen from circulating through the bloodstream. The mutation that causes the blood cell to deform is when the nucleotide adenine on the regular strand of DNA is substituted for thymine. Symptoms of this disease include pain and swelling. The goal…

Abstract Geneticvariationsareappearedduetodifferentfactors. Thesevariationsmayhave a negative, positive or neutral impact on human. Genetic variations which have nega-tive effects always tend to have a considerable impact on the susceptibility of causing a disease. Understanding human genetic variation is currently believed to reveal the causeofindividualsusceptibilitytodiseaseandtheseverityofdisease. Therearerisks, limitations and challenges of genetic variation detection. Approaches like…

Sickle Cell Anemia is an inherited blood disorder that mostly affects people of African ancestry, but it can also occur in other ethnic groups such as Middle East and Mediterranean descent (National Institute of Health). The disease affects the hemoglobin molecule in the red blood cells. Hemoglobin helps with carrying oxygen from the lungs and delivering it to different parts of the body. The mutation of this disease makes the cells become abnormal and irregular shaped. As a result, the abnormal…
