Pre-Reading Notes (Very Short Introduction - Chapter 5; Fundamentals of Forensic Science – Chapter 11): • Red and white cell blood antigens are polymorphic: they exist in more than one form and everyone inherits one or more forms of each of them • A successful DNA profile makes it possible to reach a conclusion that a DNA sample came from a specific individual‚ giving law enforcement and forensic science a new‚ powerful identification tool that complements fingerprints and other methods of identification

of the isomerase domain from a spliceosome-correlated cyclophilin‚ PPWD1 which is known as peptidylprolyl isomerase domain and WD repeat containing 1 or peptidylprolyl isomerase containing WD40 repeat‚ has been solved to 1.65 A ˚. PPWD1 acts as a protein-coding gene and its related pathways are mRNA splicing. An important paralog of this gene is PPIL2. This polypeptide encodes an N-terminal WD40 repeat domain as well as a C-terminal domain homologous to Cyps. PPWD1 was previously

PROTEINS AND NUCLEIC ACIDS 28/11/13 Qn. Which two of the four macromolecules do you believe to be the most important for life? Give evidence to support your suggestion (include a full description of the macromolecules you describe both in terms of structure and function) Introduction All the four macromolecules=lipids‚ proteins‚ carbohydrates and nucleic acids= are essential for the functioning of an organism ’s body (Campbell‚ biology). They work hand in hand to help us survive. For example

Biology II Step 1: How will you identify the “vital” cellular protein that the virus targets for degradation? (Hint: think proteomics). (3 pts.) First‚ since we know the viral RNA sequence and its targeting protein‚ we can investigate it in bioinformatics database‚ and can acquire some clues or hints about the target proteins. From the bioinformatics database‚ we might be able to find its structure‚ similarity with other proteins‚ functions‚ and binding domains. In other words‚ we can get some

1. PROTEIN is composed of amino acids. It is required to synthesize and repair muscle and other tissues and maintain fluid and acid-base balance in the body. Proteins also function as enzymes‚ hormones‚ and transporters. If necessary‚ the body uses protein to meet energy needs (4 kcals per gram). Excess kcals from protein are stored as body fat. If you consumed 60 grams of protein in a day‚ how many kcals would this convert to? (Choose your answer and delete the rest). (1 point) b)

Mitochondria - Take in glucose via proteins that pass the plasma membrane and after it journey through the cytoskeleton to the mitochondria inside the cytoplasm. Endoplasmic Reticulum - Both ER types are covered in making essential cellular segments. For the most part in charge of the combination and handling of proteins that are either emitted from the cell or that end up stuck in the plasma film. The lipids made in the SER are joined with phosphorous to make phospholipids‚ the most inexhaustible

called the perinuclear space. The nucleus contains the cell’s DNA. This complex molecule carries the information‚ which the cell needs to divide and carry out all its cellular processes. Inside eukaryotic cells‚ the DNA is associated with histone proteins‚ and is called chromatin. When the DNA is transcribed into RNA the structure of the chromatin changes to allow the RNA polymerase enzyme to access the DNA strand. When the cell divides to form new cells‚ the chromosomes coil up more tightly than
