1. How is DNA different from mRNA? DNA contains an organsisms original set of genetic instructions whereas mRNA is a copy of this genetic material copied as it is capable of leaving the nucleus of the cell. DNA is a relatively very long chain composed of two sugar phosphate backbones as well as the bases […]

1. Explain the structure of DNA- use the terms nucleotides, anti-parallel strands, and complimentary base pairing. DNA (or deoxyribonucleic acid) is essentially a large polymer made up of several nucleotide monomers. The polymer itself consists of two sugar-phosphate “backbones” that operate as anti parallel strands (one strand is inverted to the other strand). DNA is […]

1. Describe the process of translation; initiation, elongation, and termination. Initation begins when the mRNA binds to a small ribosome subunit, the two ribosome subunits bond together and search for the word “AUG” in order to start the second process, elongation. Elongation occurs while the ribosome holds onto the mRNA, the tRNA then collect amino […]

1. When does DNA replication occur? DNA replication will occur just prior to cell division. DNA will undergo its semi-conservative process and will begin its three stages of replication. 2. Name and describe the 3 steps involved in DNA replication. Why does the process occur differently in the “leading” and “lagging” strands? The three steps involved […]
