Polypeptide backbone - Study guides, Class notes & Summaries

The structure of a strand of DNA. - Answer-it is a double helix, like a twisted ladder. the ladder rings are nucleotide subunits and they have a covalent bond to the sugar phosphate backbone (made of deoxyribose and a phosphate group) What are the nucleotide subunits? - Answer-adenine, guanine, cytosine, and thymine How are the subunits held together? - Answer-through a hydrogen bond What are the nucleotide subunits compliments? - Answer-Adenine and thymine cytosine and guanine How does D...

True or false: Generally, the total number of nonpolar amino acids has a greater affect on protein structure than the exact order of amino acids in a polypeptide chain. - CORRECT ANSWER-False. The order in which amino acids are linked is unique for each protein and is the most important factor in determining the overall protein factor. True or False: The "polypeptide backbone" refers to all atoms in a polypeptide chain, except for those that form the peptide bonds. - CORRECT ANSWER-False. ...

What are R-Groups? - Every amino acid has another atom or group or atoms bonded to the central atom known as the R group. This R group gives each amino acid proteins specific characteristics, including size, polarity, and pH. What are proteins? - Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs. What is a cell? - Cells are the basi...
