Quick Questions
1) All but one of the common amino acids has the same general structure. (True / False)?
2) All amino acids have an amine group attached to a central carbon atom. (True / False)?
3) Amino acids are the monomers used to build polypeptides and proteins. (True / False)?
4) Some of the R-groups on some of the amino acids are hydrophilic. (True / False)?
5) A peptide bond is the name give to the group of atoms that hold the R-groups onto the amino acid central carbon atom. (True / False)?
6) Polypeptides are chains of amino acids. (True / False)?
7) Polypeptides can be linear or branched chains. (True / False)?
8) The primary sequence of a polypeptide chain is the location where the branch points occur. (True / False)?
9) Hydrophilic amino acid R-groups are always found on the inside of the molecule after it has folded into its tertiary structure. (True / False)?
10) All proteins have quaternary structure but not necessarily any secondary structure. (True / False)?
11) Enzymes are amino acids found in those proteins that regulate chemical reactions. (True / False)?
12) Nucleic acids are only found in eukaryotic cells and never in prokaryotic cells. (True / False)?
13) The general structure of a nucleotide consists of a glucose molecule, a phosphate sugar and a nitrogenous base. (True / False)?
14) There are two types of sugars found in different nucleotides; ribose and deoxyribose. (True / False)?
15) Ribose sugars are found on one chain of the DNA molecule and deoxyribose sugars are found on the other chain of the DNA molecule. (True / False)?
16) RNA molecules are always found in cells undergoing protein synthesis. (True / False)?
17) Ribose sugars and deoxyribose sugars have the same number of oxygen atoms in their molecular structure. (True / False)?
18) RNA molecules are single stranded. (True / False)?
19) DNA molecules always contain the nitrogenous base thymine. (True / False)?
20) DNA nucleotides have more phosphate than RNA nucleotides. (True / False)?
21) A DNA molecule has a double helix at one end of the molecule and a single helix at the other end of the molecule. (True / False)?
22) RNA molecules are made by copying the sequence of bases along certain selected stretches of the DNA molecule. (True / False)?
23) Genetic information is usually held in the sequence of nitrogenous bases along a DNA molecule. (True / False)?
24) During cellular division DNA molecules and the information they contain are copied. (True / False)?
25) RNA carries no information, only DNA carries biological information. (True / False)?
