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...

Central Dogma - correct answerDNA-(Transcription) - RNA- (Translation) -Protein DNA Structure - correct answer1. Deoxyribose: 5 Carbon atoms are numbered 1' to 5' . Hydrogen attached to 2'. Sugar 2. Phosphate group Sugar-Phosphate backbone is asymmetric because PO4 groups connect the C5' of a sugar with the C3' of neighbouring sugar. = Asymmetric ends because the C5' end is attached to a PO4 and the C3' end is simply a hydroxyl group of the sugar. 3. Nucleic Acid: No-covalently bon...

PAX Prep NLN Verbal Comprehension Passages The way Things Work It was the ancient Greeks who first had the idea that everything is made up of elements. They conjured up just four of them-earth, fire, wind and water. As it turned out, the idea was right but the elements were wrong. Modern elements are less evocative but more numerous. They make up just over one hundred basic substances. Some are commonplace, like hydrogen, oxygen, iron and carbon; others are rare and precious, such as mercu...

The most common isotope of hydrogen has one proton, no neutrons, and one electron. An isotope of hydrogen with 1 neutron would have: - Answer- an atomic number of 1 and a mass number of 2 In a covalent bond: - Answer- electrons are shared between atoms so that all atoms have full outer shells A property of a system that is present at one level of organization but absent at the levels below is called: - Answer- an emergent property An ionic bond is - Answer- weaker than a covalent bond ...
