Answer:
Hi! I think that it is D. I am not 100% sure on it though so I'm so sorry if thats
wrong. Hope this helps though!
For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.
Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-
1. Denaturation of the double-stranded DNA (at around 95°C)
2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)
3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).
With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.

The daughter cells are produced with only half the chromosomes of the parent cell. The correct option among all the options given in the question is option "D". So the main goal of meiosis is actually creating four daughter cells that are by no means similar to the parent cells.
When these daughter cells that
are created combine together and undergo the process of fertilization, then a
zygote is formed and the development of cells starts. The process of meiosis
can be asexual as well as sexual.
The atomic number is 5. The atomic number gives the number of protons. Protons which have a positive charge are balanced by an equal number of electrons in a neutral atom. Boron number 5 has five protons and therefore as a neutral atom also has five electrons. Boron atomic number 5 has five electrons in its ground state. Commonly Boron will lose 3 electrons leaving 2 electrons in its most common ionic form.
