5 True/False questions

  1. anaphaseSecond Stage of Cell division: Centromeres of duplicated chromosomes are aligned at plate. chromosomes become attached to spindle fibers


  2. Cell Theory1. All living things are made of cells


  3. codonA sequence of three nucleotide bases on mRNA that refers to a specific amino acid. (if DNA triplets are AAT-CGT-TCG then related _____ on mRNA would be UUA-GCA-AGC
