GATA-type zinc finger domain that binds to DNA sites with the consensus sequence (A/T)GATA(A/G). This type of “zinc finger” domains consist of a consensus sequence of C-x2-C-x17-C-x2-C ‚ which means one Cys‚ two any amino acids‚ one Cys‚ 17 any amino acids‚ one Cys‚ two any amino acids‚ and one Cys. Please use this consensus sequence‚ and write an equivalent regular expression pattern. 1) Record the regular expression

A Can of Bull? Do Energy Drinks Really Provide a Source of Energy? Objectives • Describe and categorize chemically the components of various popular “energy drinks.” • Determine the physiological role of these components in the human body. • Explain scientifically how the marketing claims for these drinks are supported (or not). • Determine under what conditions each of the “energy drinks” might be useful to the consumer. The Case After spending several years working the Sport’s Desk of the Lansing

known as sigarilyas. Abstract Winged bean (Psophocarpus tetragonolobus) has higher protein content than soy bean (Glycine max) and potato (Solanum tuberosum Linnaeus). Amino acid analysis showed that winged bean contained all amino acids in sufficient quantity‚ with the exception of the sulphur-containing amino acids. The amino acid content of immature pods was generally lower‚ and the non-protein nitrogen content higher. The seed showed a high content of hemagglutinins. Hemagglutinins are agents

The primary structure of a protein represents: (*) the amino acid sequence. (2) the functional configuration. (3) the subunits of a protein. (4) a pleated sheet. (5) a alpha helix. 2. In prokaryotes‚ most genes are organized into operons. One component of an operon is the structural genes. Which of the following

As stated above the androgen receptor-coding gene is located in band Xq11-q12 on the long arm of the (X) chromosome. This portion of the X chromosome is about 90kb and contains 8 exons that code 919 amino acids with a mass of approximately 110kDa. These many amino acids determine the structure of the transcription factor protein involved in steroid-hormone activation. The androgen receptor has several functional domains‚ which are inconsistently classified among various literature. In general the

the assay nearly 100 times more sensitive than the Biuret reaction alone. The BCA Assay: The BCA assay is a two step assay‚ in the first step Cu2+ is reduced to Cu1+ by forming a complex with protein amide bonds. In the second step‚ Bicinchoninic acid (BCA) forms a purple complex with Cu1+ which is detectable at 562nm. this assay is relatively slow unless heated. When comparing these methods to the Bradford assay‚ the Lowry method has many interfering substances‚ it is a slow reaction and the proteins

Organic compounds are very important to a body. They are help the body to do things and replenish it. The 4 organic compounds I will talk about are carbohydrates‚ lipids‚ proteins and nucleic acids. I will explain what they do and what they are made of. Carbohydrates are in foods‚ some examples are sugars and starch. The structure of a carb is ring shaped‚ it is an easy one to know. The monomer of a carb is monosaccharide‚ which means one sugar. A monosaccharide consists of glucose‚ fructose and

TITLE: The Amount of Protein in Chicken Tissues over Cooked Various Periods of Time. ABSTRACT: In this lab‚ we are using a BioRad protein assay dye to determine the concentration of protein in our chicken. The dye binds to the amino acid residues‚ which allow us to find the concentration of protein (BioRad Protein Assay for Tissues). Our hypothesis was the longer chicken is cooked the less protein is available. To test our hypothesis‚ we made samples using our chicken and distilled water to determine
