The DNA replication by the action of DNA polymerase takes place in the 3' to 5' direction on the leading strand. The lagging strand which has the opposite orientation or polarity as that of the leading strand requires a more time to get synthesised. The DNA replication of the lagging strand happens in short segments where a RNA primer forms a compliment with a part of the DNA segment on its 3' end. This RNA primer helps initiate the replication of the Okazaki fragments. When the replication on the lagging strand reaches its end, the RNA primer forms a compliment with the last bit of the strand. This small segment gets missed in the end as no more DNA is left to form a RNA primer-DNA compliment. Such shortening of the lagging strand in the replication process is the end-replication problem.
Telomeres are protective ends of the DNA strands. These ends contain a poly-A tail. When the lagging strand replication reaches its end, the RNA primer forms a compliment with the telomere and initiates the replication. This leads to the shortening of the telomere and not the coding segments on the lagging strand of DNA. The telomerase repairs the shortened telomere by re-synthesising it.
Answer:
Explanation:
This is because, during lytic cycle,
During the lytic cycle, genome willing f the virus always undergo replication and transcription and the enzymes then degraded the bacteria chromosomes which has been coded by the viral genome to produce deoxyribonucleotides that acts as monomers to in order to produce more viral DNA so that virus will be replicated the more.
The virus find it's way into the the bacteria, then take over the whole macromolecular production and degrade components that are in existence in bacteria so as to get new materials to replicate alot of copies of itself.

Answer:
A hydrogen atom is an atom of the chemical element hydrogen.Carbon is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds.
In chemistry, an element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nuclei.
