The chromosomes which have already duplicated condense and attach to spindle fibers that pull one copy of each chromosomes to opposite sides of the cell.
Dna replication needs to occurs because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. so the dna needs to be copied before cell division so that each new cell receives full set of instructions. - Google
Answer:
gene encoding enzymes for glycolysis.
Explanation:
Plasmid may be defined as an extra chromosomal circular DNA that replicate independently of the main chromosomal material. Plasmid are generally used for the manipulation of genes in molecular technologies.
Plasmid can encode gene for toxins, antibacterial resistance and for the unusual substrate degradation. The plasmid cannot code enzyme for glycolysis because these enzymes are already present in the host organisms. Glycolysis enzymes are independent on the plasmid regulation.
Thus, the correct answer is option (3).
