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.
<span>Geothermal electricity takes steam from hot water, and uses it to spin/rotate a turbine. This turbine activates a generator, which then produces electricity. By drilling into the ground and accessing underground resources of steam, that steam can then be piped directly from beneath the ground to the generator unit.</span>
I think it is D but I'm not sure, however, 4 seems pretty right.
The answer I came up with is Echinoderms and Chordates.
Happy studying!
