5 Matching questions

  1. mutation
  2. genetic engineering
  3. mutations are due to...
  4. each subunit contains...
  5. if a cell survives a mutation...
  1. a a sugar, phosphate, and a nitrogenous base
  2. b the changed instructions will be passed on to all cells coming from in
  3. c an alteration in a sequence of DNA
    -change the normal message carried by the gene, causing a defect
    - they are random
    -affect the synthesis of proteins, which causes malfunctions in the cell. EX.) sickle cell anemia is caused by a substitution in the cell
    -can cause cell death
  4. d insertion, detection, or substitution
  5. e a new technology used to alter the genetic instructions of organisms

5 Multiple choice questions

  1. technique used to separate DNA
  2. is an organic molecule made of many small subunits called nucleotides (monomers)
    -double helix molecule
  3. the cell divides to form two offspring cells, or daughter cells, each containing identical copies of DNA (mitosis)
  4. are sequences of DNA that contain a code of instructions for a specific trait
    -a human cell contains many thousands of different genes, located on chromosomes, in its nucleus
  5. contain the genetic code for all organisms

5 True/False questions

  1. for mutations to be inherited by offspring (sexual reproduction)...insertion, detection, or substitution


  2. DNA must be able to...weak hydrogen bonds with may be broken to split into DNA into two single strands


  3. single stranded DNA becomes...replicate or copy, its coded instructions


  4. transfer moleculesmove specific amino acids to the ribosome, which are strung together to make a protein (transfer RNA)


  5. sexual reproductioncontain half their genetic code from one parent and half from the other, making them similar but NOT identical
