Answer:
The correct answer will be-
1. Nucleosomes
2. Chromatin
3. Sister chroamtid
4. Centromere
Explanation:
The DNA is a very long molecule which if has to be passed on to the daughter cell as it is will cause problems. So, to reduce problems a cell form tightly packed structure of DNA so that they can be passed easily to the daughter cell.
The packaging of DNA begins with the wrapping of the DNA around histone proteins which forms the 11 nm basic structural units called nucleosomes. The nucleosomes start condensing each other and form 30 nm structure chromatin fibres.
The chromatin fibres undergo replication during S phase which produces an exact copy of the chromatin called sister chromatids bound to each other at a central point called centromere which helps the separation of the chromatids during M phase.
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.
B, metals, nonmentals all bond to be stable
Darwin's finches are a traditional illustration of an adaptive radiation. Their ancestor came on the Galapagos Island about two million years ago. With time Darwin's finches have developed into fifteen different species separated on the basis of beak shape, body size, and feeding and song behavior.
The population of finches possesses the tendency of evolving rapidly in response to a changing environment. However, they can also get extinct in condition if the weather fluctuates too briskly between the dry and wet seasons. This would most likely take place due to the immigration of genes and mutations within the genes that are conducted on to the next generations.
