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.
In case of severe burn injuries, a person experiences a sudden increase in the number of dangerous bacteria in the gastrointestinal tract approximately 32%. The increase in the dangerous bacteria increase the chance of developing gastrointestinal conditions like irritable bowel disease, and other non-related conditions like rheumatoid arthritis and diabetes.
But in case of less severe burn injuries, the dangerous bacteria accounted for just 0.5% of the bacteria. An imbalance in the bacteria cause long term health consequences, in fact some of the complications could possibly even result in death of a person with severe burn injuries.
Jet streams-Are fast flowing, narrow air currents found in the atmospheres of some planets, including earth.
Global wind belts-Are formed by 2 main factors which is the unequal heating of the earth by sunlight and the earths spin.
