Answer:
C is not a principle of the Cell Theory.
Explanation:
If this is based off opinion, i believe it should be banned, why would you make it easier for criminals? DNA is one of the easiest and most reliable ways to identify a body, what happens when someone away from home passes away and they cant be identified? it could also cause problems for tons of foster children tracking their birth parents. and it'd make it much easier to steal an identity or fake a death, over all it could have a few pros it'd also have many cons. if anyone has an argument id love to hear your thoughts ☺
If this happened we would just keep getting g lots of the same thing
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.
