Document Summary
Clicker questions: my son jay as a unique combination of alleles as a result of cutting and pasting dna backbones. When did this cutting and pasting occur: when he was a newly fertilized zygote, when he was a developing fetus, when he reached sexual maturity d) none of the above. Which type of bacterial genetic exchange involves donor cells that are dead? a) b) c) conjugation transduction transformation. Bacterial dna can be moved from donors to reciepients. Dna can be incorporated into a recipient through recombination. Some genes are mobile so can be transferred to another site then to another host. F factor is a plasmid that codes only for its own replication. This is even smaller, just the red part, a little bit of dna all it does it code for its own replication and transfer. It sends a copy of itself from the bacterial chromosome to the other red part on the plasmid.
