Treatment of cells with the chemical colchicine interferes with microtubule assembly in metaphase and anaphase. What are the resulting mutations? - -Nondisjunction mutations deletion mutation - -a mutation in which one or more pairs of nucleotides are removed from a gene Insertion - -A mutation involving the addition of one or more nucleotide pairs to a gene. An error in DNA replication leads to adding an extra cytosine. This causes the DNA sequence CTCGTT to change to CCTCGTT. Which type o...
