In one paragraph, discuss the structure of Polypeptides and Nucleic acids
BRCA1 and BRCA2 Genes Discuss how the primary structure of nucleic acids is the order of bases in the polynucleotide sequence, and the secondary structure is the three-dimensional conformation of the backbone. Discuss the monomers of nucleic acids are nucleotides. Discuss how the bases are bonded to the sugars, forming nucleosides. Summarize how nucleosides are linked by ester bonds to phosphoric acid to form the phosphodiester backbone. Specific proteins called single-strand binding proteins bind to the single-stranded regions and protect...
Ribose is an important pentose sugar in the structure of nucleic acids. The linear structure for D-ribose is shown below. Use the methods we discussed in class (also in Timberlake) to convert the linear form below into the corresponding. Haworth structure for the beta anomer of D-ribose. Is the cyclic structure an acetal or a hemiacetal?
Proteins have many diverse functions. Carbohydrates, nucleic acids and lipids do not have diverse functions in a cell. Proteins are polymers of amino acids. Discuss how the structure of amino acids allows proteins to perform so many functions.
Compare the structure of the four major biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids) and explain how the distinct structure of each type of molecule enables it to carry out its particular function.
Why is CD Spectroscopy a useful tool for characterizing nucleic acid structures? Why are nucleic acids perfectly applicable for CD analyses? Name and describe another instrumental method for charactering the structure of DNA and RNA?
Nucleic Acids List the two types of nucleic acid polymers. Describe how information flows from DNA >> RNA >> proteins List the 3 major components of a nucleotide. Describe how these monomers are linked to form a nucleic acid. Distinguish between DNA and RNA. Briefly describe the three-dimensional structure of DNA.
Which facts about nucleic acids are true? 1. Nucleic acids are homopolymers. 2. Every polymerized monomer unit carries a negative charge at physiological pH (6.5-8.0). 3. Successive monomer units in nucleic acids are connected through a phosphodiester linkage. 4. RNA and DNA are strong acids. ► View Available Hint(s) 2 and 3 O 2, 3, and 4 O All statements are true. 3 and 4
There are two types of nucleic acids, DNA and RNA. Nearly all organisms use DNA, not RNA, as the central repository for genetic information. Choose the statements that explain this phenomenon. DNA contains adenine as one of its nitrogenous bases. DNA has a double‑stranded structure that ensures an accurate mechanism of duplication. DNA contains an −OH−OH group at the 2′2′ carbon. DNA is flexible and forms complex catalytic structures. DNA is more resistant against enzymes that break down nucleic acids.
Most polypeptides are rather large. They contain at least __________ amino acids.
60) Lipids are composed of: c) fatty acids and glycerol amino acids and glycerol nucleic acids and glycerol fatty acids and water fatty acids and sugar e) 61) The bond between two amino acids is a: a) hydrogen bond b) covalent bond c) peptide bond d) b and c e) none of the above 62) Hemoglobin has which tertiary structure: a) fibrous b) globular c) four subunits--two alpha chains, two beta chains d) alpha helix e) none of the above...
