6 Multiple choice questions

  1. Those "nonbiological" factors that are involved in a person's surroundings such as the nature of the people who raise them, the person's friends, and the person's behavioral choices.
  2. DNA wrapped around histones (spools) forms long DNA strands into "beads on a string".
  3. A section of DNA that codes for the production of a protein or a portion of a protein, thereby causing a trait.
  4. mRNA.
    The RNA that performs transcription (the first step in protein synthesis). It copies the coded message from DNA in the nucleus and carries the message into the cytoplasm.
  5. Complex network of DNA coiled around and supported by proteins, found in the nucleus of the cell.
  6. The region that joins two sister chromatids.

5 True/False questions

  1. transcriptionThe second part of protein synthesis whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm.

          

  2. transfer RNAThe second part of protein synthesis whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm.

          

  3. interphaseThe region that joins two sister chromatids.

          

  4. translationThe first step in protein synthesis by which a DNA template is used to produce a single-stranded mRNA molecule that's a negative image of that DNA portion.

          

  5. genetic factorsThe general guideline of traits determined by a person's DNA.
