How do materials enter and leave the nucleus? Nuclear pores, small channels that span the nuclear envelope, let substances enter and exit the nucleus. Each pore is lined by a set of proteins, called the nuclear pore complex, that control what molecules can go in or out.
Replication is the process where DNA molecules copies itself to form another DNA molecule during cell division. it involves several enzymes which includes DNA helicase, the enzyme that unwounds the DNA double helix. RNA primase, it is an enzyme that creates an RNA primer. DNA polymerase, it is the enzyme that matches and lays down nucleotides to form the new DNA daughter. DNA ligase joins the Okazaki fragments by catalysing the formation of phosphodiester bond.
