This quiz is based on the various aspects of the structure of protein molecules and amino acids. 1. The sequence of different amino acids in the polypeptide chain of a protein is called its : • primary structure • secondary structure • tertiary structure • Quaternary structure
In its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases. Watson and Crick proposed that the DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix. Base-pairing takes place between a purine and pyrimidine: namely, A pairs with T, and G pairs with C.

The head section of the molecule likes water (hydrophilic) while the tail does not (hydrophobic). Because the tails want to avoid water, they tend to stick to each other and let the heads face the watery ( aqueous ) areas inside and outside of the cell.

In DNA or RNA, the four nucleotide monomers act like the letters of the alphabet to communicate information. The specific sequence of hundreds or thousands of nucleotides in each gene carries the information for the primary structure of proteins, the linear order of the 20 possible amino acids. DNA adenine methylase, (Dam methylase) (also site-specific DNA-methyltransferase (adenine-specific), EC 126.96.36.199, modification methylase, restriction-modification system) is an enzyme that adds a methyl group to the adenine of the sequence 5'-GATC-3' in newly synthesized DNA. A strand of DNA is exposed to intense heat. Which statement BEST describes what will happen to the strand of DNA? The chemical bonds of the DNA molecule will be broken.
