The correct answer is:
Nucleus
Prokaryotic cells do not contain <u>a nucleus</u>.
They are called proteins.
It begins with the unzipping of the double helix by
helicases. Unzipping forms y-shaped replication forks
exposing promoter regions (TATA regions) where the initiator proteins and factor bind to
the regions of DNA. A primer also
attaches to the region. DNA polymerase then
binds to the regions and begins adding DNA nucleotides
to the 3’ end of the primer based on the nucleotides on the template strand. Topoisomerase continues to unwind the DNA as the
polymerase progresses to the end of
replication.

Answer:
c. Protons, electrons
Explanation:
The number of these electrons in a neutral atom is equivalent to the number of protons.
Since protons have positive charge, they balanace the negative charge of electrons. Electrons have same level of charge per particle as a proton.
Neutrons posses no charge, so in a "neutral atom" the number of proton is equal to that of electrons, othermeans it will not be neutral.
When a electron is removed by natural or artificaial means , an ion results which is an electrically charged particle. It also happens some atoms take additonal electrons once they were previously neutral. They can also lose electrons and become positively charged,
