5 Written questions

5 Matching questions

  1. replication fork
  2. transformation
  3. radioactive isotope
  4. semiconservative model
  5. primer
  1. a Type of DNA replication in which the replicated double helix consists of one old strand, derived from the old molecule, and one newly made strand.
  2. b A short stretch of RNA with a free 3' end, bound by complementary base pairing to the template strand, that is elongated with DNA nucleotides during DNA replication.
  3. c An isotope (an atomic form of a chemical element) that is unstable; the nucleus decays spontaneously, giving off detectable particles and energy.
  4. d A Y-shaped region on a replicating DNA molecule where the parental strands are being unwound and new strands are growing.
  5. e (1) The conversion of a normal animal cell to a cancerous cell. (2) A change in genotype and phenotype due to the assimilation of external DNA by a cell.

5 Multiple choice questions

  1. Nucleotide sequences, usually noncoding, that are present in many copies in a eukaryotic genome. The repeated units may be short and arranged tandemly (in series) or long and dispersed in the genome.
  2. The sugar component of DNA nucleotides, having one fewer hydroxyl group than ribose, the sugar component of RNA nucleotides.
  3. A protein that breaks, swivels, and rejoins DNA strands. During DNA replication, topoisomerase helps to relieve strain in the double helix ahead of the replication fork.
  4. Site where the replication of a DNA molecule begins, consisting of a specific sequence of nucleotides.
  5. Member of the prokaryotic domain Bacteria.

5 True/False questions

  1. pyrimidineOne of two types of nitrogenous bases found in nucleotides, characterized by a six-membered ring. Cytosine (C), thymine (T), and uracil (U) are pyrimidines.

          

  2. double helixA dense region of DNA in a prokaryotic cell.

          

  3. chromatinThe complex of DNA and proteins that makes up a eukaryotic chromosome. When the cell is not dividing, chromatin exists in its dispersed form, as a mass of very long, thin fibers that are not visible with a light microscope.

          

  4. template strandThe new complementary DNA strand synthesized continuously along the template strand toward the replication fork in the mandatory 5'?3' direction.

          

  5. primaseA short stretch of RNA with a free 3' end, bound by complementary base pairing to the template strand, that is elongated with DNA nucleotides during DNA replication.
