I think is D,,,,,,,,,,,,,,,,,
The best answer is A.
The lytic cycle is considered the main cycle in viral replication. Once the viral DNA enters the cell, it transcribes itself into the host cell's messenger RNAs and uses them to direct the ribosomes.
The host cell's DNA is destroyed and the virus takes over the cell's metabolic activity and begins to use the cell's energy for its own propagation and within a short while, when the cell gets overcrowded with the viral progeny, the original virus releases enzymes to break the cell wall. The cell wall bursts. This process is called lysis. The new viruses are then released.
The answer is B. a nucleus.
Prokaryotic cells do not have a nucleus. They have ribosomes, a cell membrane, a cell wall, and DNA, but lack a nucleus. Prokaryotes also don't have mitochondria or chloroplasts and generally lack organelles.
Answer:
Equal amounts of DNA contain equal proportions of nitrogenous bases.
Explanation:
According to Chargaff's rule, the nitrogenous base pairs (Purines and pyrimidines) have an equal ratio (1:1) in the DNA of all the organisms. More precisely, the amount of adenine is equal to thymine and the amount of guanine is equal to cytosine in the DNA of all the organism. A-T base pair has two H-bonds while G-C base pair has three H-bonds.
