<u>Answer and Explanation:</u>
You will find the complete answer and explanation in the attached file due to technical problems.
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:
Francesco Redi's experiment was the first experiment that disproved the theory of sponatenous generation. He explained that life cannot originate from the inorganic or non living matter.
He placed the two maggots in two different jars. The one jar is uncovered and contains meats in which maggots appear. The another jar is covered and no maggots appear on meat. This explains that maggots flies eggs are not formed in the covered jar as eggs are not available for the life. Maggots do not originate from the meat.Life originate from the pre existing life.
