What are the terms describes the dna–protein complexes that look like beads on a string?
A) Chromatin
B) 30-nanometer fibre
C) Histones
D) Nucleosome
The correct answer is option D
Explanation: A Nucleosome is the basic fundamental unit of a DNA, and the fundamental sub-unit of a Chromatin.
The Nucleosome is the basic packing unit of DNA,it is built from histone proteins. A nucleosome is made up of 8 histones proteins resembling a thread wrapped round a spool.
The smallest bundle of DNA is known as a Nucleosome,a Nucleosome is produced through interaction between DNA and histone proteins.
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.
