DHN 311 exam 1 Questions with Complete Solutions

List the major steps of the "central dogma" of molecular biology. What are the products of each step? Correct Answer-Replication --> DNA Transcription --> RNA Translation --> protein Once the DNA strands unwind and separate, DNA polymerases copy the DNA. What are they copying? What characteristics of DNA necessitates the need for leading and lagging strands to copy the DNA? Correct Answer-They are copying ____. DNA is antiparallel so the mode of synthesis occurs in 2 different ...

Covalent Bond Correct Answer-Form between non-metals and share electrons Nonpolar covalent bond Correct Answer-Has no net charge and share electron equally between atom Polar covalent bond Correct Answer-One atom is slightly more positive than the other and unequally share electrons Electronegativity Correct Answer-The net ability of an atom to attract an electron from another atom. An atom with high electronegatvity is an electron Correct Answer-Acceptor An atom with low electron...
