>C=0 attractions as well as hydrogen bonding since there are two sites on the molecule for hydrogen bonding, dimers are readily formed for the lower members of the series. Although each interaction is minute, collectively, even the weakest of intermolecular forces can add up to give an impressive effect. We can see in the table above that even though Butanoic acid

To deduce if UV Radiation induced a mutation in the DNA of Serratia Marcescens and prevented the production of the red pigment called Prodigiosin. Hypothesis: Maybe the disappearance of red color in Serratia Marcescens is caused by the UV light which induces mutations in its DNA and is known as a common mutagen. Prediction: If UV light mutates the DNA of Serratia Marcescens then the red pigment colonies of the bacteria will no longer be produced. Independent Variable: Ultra Violet Radiation

oxygen from the lungs to the tissues, hemoglobin is the protein involved in the transport of oxygen in the human body (1). Most hemoglobin in humans exists as the tetramer denoted as α2β2, also known as Hemoglobin A or HbA. It consists of 2 pairs dimers, α1β1 and α2β2, which are linked at the α1β2 contact sites (2); the α subunits are made of 141 amino acids, and the two β subunits are made of 146 amino acids. Each subunit consists of a protein chain covalently bonded to a heme prosthetic group,

asialo and sialoglycoproteins (glycophorins). These glycoproteins are determined by the presence of sialic acid which is the negative charge on cell surface. GpA is the primary sialoglycoprotein of human erythrocyte membranes that forms noncovalent dimers by sequence-specific, reversible association of its single hydrophobic membrane-spanning domain2. The glycophorin

PHYSICAL EXAMINATION: Mr P is alert, orientated and responds appropriately to questions. He is clean shave with low hair cut. He is Height 183cm weight 88kg, Body Mass Index (BMI) 26.3, which shows that he is overweight. He appears to be anxious and in moderate to severe distress, his hands are moist and cold. His colour is good; he lies flat with moderate chest discomfort. Vital signs: Blood pressure (BP) Right hand 167/95, left hand 170/98, and no significant difference in BP of both arms. Cardiac

The difference between the two structures is a result of 15degrees of rotation between both the alpha-beta dimers (Keates, 2004). As a consequence of the rotation, in the F helix the bonds between the side chains of the alpha-beta dimers change, causing a change in position of the heme molecule. In the presence or absence of oxygen the tense and relaxed structure can move accordingly. Cooperativity of the heamoglobin molecule

The specific topic being addressed by the members of this group is: Describe the molecules responsible for regulating the human circadian clock and how they affect metabolism in the human body. Be sure to address how the circadian rhythms are governed, the signaling mechanisms used, and specific metabolic pathways. Note you do not need to discuss each step in the metabolic pathway (e.g. you don’t need to describe all ten steps of glycolysis if that’s a pathway that is affected,) but you should identify

conformation is that a signal –stranded viral RNA packaged into the assembling capsid and reverse-transcribed into DNA in this compartment. (2, 3) HBV capsids are commonly in which they present two distinct icosahedral geometries, composed of 90 and 120 dimers with masses of ≈3 and ≈4 MDa, respectively, corresponding to triangulation numbers of T = 3 and T = 4 and nominally consisting of 180 and 240 subunits. (4, 5, 6) Capsid protein has a 140-resudue N-terminal core domain which is connected to a 34-residue

INTRODUCTION Double stranded breaks (DSB) occur frequently in eukaryotic cells. It can be caused by many factors such as ultra violet radiation, reactive oxygen species, ionizing radiation et cetera (Lieber,2010). DNA damage leads to rapid growth of tumor leading to cancer. Hence it is very important to repair it before the cell undergoes further division. Two mechanisms of repair system can occur in the cell – homologous recombination (HR) and non homologous DNA end joining (NHEJ). These repair
