dependent transcriptional activation domain AF-2. Upon the agonist binding‚ AF-2 take an active conformation that allow it to bind the coactivators. AF-2 consists of the hydrophobic residues of helices 3‚ 4‚ 5 and 12. So‚ when the agonist is binding‚ helix 12 would take a conformation that allow it to complete the hydrophobic surface of AF-2 allow binding to LXXLL motifs of the coactivator [3]. The nuclear receptors are different in which motif they are binding to. For instance‚ GR and PR prefer binding

fork 3.5 Regulation 3.6 Termination 4 Polymerase chain reaction 5 References Background on DNA structure [edit] DNA usually exists as a double-stranded structure‚ with both strands coiled together to form the characteristic double-helix. Each single strand of DNA is a chain of four types of nucleotides.

Deoxyribonucleic Acid (DNA) DNA stands for deoxyribonucleic acid‚ it is located in the nuclei of cells which make up the body. DNA is quite often referred to as one of the building blocks of the body.. It is made up of four bases known as: • Adenine • Guanine • Cytosine • Thymine James Watson‚ Francis Crick‚ Maurice Wilkins‚ Rosalind Franklin Crick and Watson‚ together with Maurice Wilkins‚ won the 1962 Nobel Prize in physiology or medicine for their 1953 determination of the structure of

nucleotides that twist together in a spiral known as a double-helix. Jell-o is made from long strings of amino acids‚ the fundamental building blocks of proteins‚ with a bit of hydrogen attached. How Jell-o works. Jello has 5 basic ingredients: gelatin‚ water‚ sugar‚ food coloring‚ and artificial flavors. Gelatin has a structure similar to DNA. with DNA there are two chains called nucleotides that twist together in a spiral known as a double-helix. When you add the flavor and gelatin mixture to boiling

Study Guide 3/1/11 1. Describe the three parts of a nucleotide and how they bond to form a nucleotide. The three parts of a necleotide are a carbon sugar‚ a phosphate group and a nitrogenous base. The carbon sugars bond to the phosphate groups by covalent bonds while the nitrogenous base bonds with it’s compliment by hydrogen bonds. 2. Summarize the role of covalent bonds and hydrogen bonds in the structure of DNA. The role of covalent

some slight confusion because the general public knows that DNA houses the ‘blue prints” of our anatomy. However‚ this is the difference: DNA is a double helix which means that it has 2 strands. RNA however‚ has a single strand‚ so it is started but incomplete; which means that it needs another complimentary strand to become a complete DNA helix. So when reproduction occurs‚ both parts‚ male and female‚ combine each of the two strands given to form the offspring’s DNA and significant shape. If you

of within Collagen molecules is a triple helix formed when three chains of amino acids wrap around each other to give a ropelike arrangement of polypeptide chains. Collagen molecules are very long‚ thin‚ and rigid. Collagen polypeptides contain a large amount of proline and hydroxyproline and include a glycine residue at every third position. Proline helps in the formation of helical formation of each alpha chain. Each chain forms a narrow left-handed helix‚ and three chains coil around each other
