Two to three percent of infants, within the first year of life, are allergic to cow’s milk. Although most differences between cow and human milk don’t cause many problems for people, the Beta Lactoglobulin protein is a major cause of allergic reactions. The Beta Lactoglobulin (BLG) allergen is a whey protein present in milk. In order to decrease the concentration of the BLG protein, researchers found that producing an individual with a non-functional version of the gene would silence the effects

The unique and primary proteins of DNA, the highly basic histone proteins have been found to be ubiquitous and conserved among eukaryotes. DNA and histones co-exist as a closely associated and highly coiled structure. The purpose of such a structural organization is to compact DNA; which would otherwise be too long to be accommodated within the restricted boundaries of a single cell. Core histones (H2A, H2B, H3 and H4) and Linker histones (H1) are the two types that this unique protein is composed

Rett syndrome (RTT). RTT, identified for the first time in 1966 by Andreas Rett, is a rare genetic neurodevelopmental disorder that occurs predominantly in girls. The clinical features include growth failure, psychomotor regression, characteristic repetitive stereotyped hands movements, and severe problems with language, learning and coordination development. Other signs involve breathing abnormalities, seizures and scoliosis (Leonard H, Cobb S, Downs J. Clinical and biological progress over 50 years

nucleotide triplets of the messenger RNA into the 20 symbol code of amino acids that shape the polypeptide chain of the proteins. The process of RNA transformation, begins from its 5 end towards its 3 end as the polypeptide chain. In addition, it is manufactured from its amino terminal to its carboxyl-terminal. There are no important changes in the protein synthesis phases in prokaryotes and eukaryotes, though there is one main difference among the construction of the RNA, and that is that prokaryotes regularly

The main purpose of primase in DNA replication is to synthesize RNA; it makes RNA oligonucleotides that are used as primers for DNA synthesis. Without this, DNA Polymerase could not start a new chain of DNA, so primase serves as a starting point for replication. After Helicase breaks the strands apart, primase comes in to add short, new RNA nucleotide chains (about 10 nucleotides long) to the template strand. Then the DNA polymerase can add new DNA

Mei Yun Lin Quiz for GS616 - Genetics discussion section – Short Answers 20 points total (2/2 points) 1) What is a loss-of-function experiment? Loss of function experiments, such as in a gene knockout experiment, in which an organism is engineered to lack the activity of one or more genes, resulted in gene product to have less or no function. It is very commonly used in the research, and it can reduce or abolish protein function. (3/3 points) 1) What is a gain-of-function experiment? Gain

phosphate backbone generally expressed as PO4^-3 provides support for the nitrogenous bases [also bonding through ester bonds. The nitrogenous bases in DNA are divided into two Purines [Adenine and Guanine] and Pyrimidines [Thymine, Cytosine, and uracil in RNA] Purines are double ring structures, and Pyrimidines are Single ringed. In other words, they provide the perfect asymmetry of the DNA double helix. When Watson and Crick did their DNA model, they noticed that two Purines bonded together meaning for

DNA Designer The research question of the article Designer DNA by Rachel Berkowitz was how the deoxyribonucleic acid (DNA) portrays a unique sequence of protein for every organism. Biologically, all animals including humans have a unique DNA. The study focuses on how the arrangement of four nucleotide bases determines the DNA sequence. For decades, scientists have altered the DNA of various organisms to manipulate the life of living things. They have inserted genes into algae, yeast cells, and bacteria

Have you ever argued with yourself with which carbon compound was the one we need for survival. You could have chosen carbohydrates, lipids, or proteins. I choose proteins. I claim that proteins are the best carbon compound because proteins are building blocks, protein is a micronutrient, and proteins maintain fluid balance. One reason I chose proteins is because proteins are building blocks. Proteins make up hair nails, bones, muscles, cartilage, skin, and blood. Proteins also make up the

RESULTS Agarose GE: Figure 1 shows the results of amplifying five types Arabidopsis thaliana fwa gene. successful PCR was a result of nice bands showing in figure 1. Wild type undigested (900bp), mutant undigested(860bp), and mutant digested (850bp) were all showing band in the same location. On the other hand, Wild type digested did not show any bands meaning amplification did not occur because McrBc digests fwa enzyme that is being methylated. Gel electrophoresis was used to determine the size
