Question

Which of the following is the most disorganized? A. sister chromatid; B. chromatin; C. double helix; or D. chromosome

Answer 1

The answer is b, chromatin

Explanation:

To answer this question you have to know how each given term, in the multiple choice, looks like and pay attention to the most "disorganized form of the DNA". To solve this you have to know what means organized in a more biological way. Organized means it is arranged systematically and that it has some kind of order.

1. A, sister chromatid
`->`one chromatid which is part od two identical DNA molecules held together by a single centromere
This form looks organized.

2. B, chromatin
`->` "unwound DNA" that is found in the Interphase and made of DNA, RNA, histone and non-histone proteins
`->` unorganized DNA, proteins etc., chromatin becomes organized into 46 pieces, in human cells, called chromosomes during cell division

Chromatin on the picture above reminds me of spaghetti in a bowl as you can see on the picture below. Is this spaghetti organized? No, it is messy! Does this chromatin look organized? Does it have a fixed shape? No, therefore it is disorganized and this is our correct answer.

After you got your answer, always check other solutions.
3. C, double helix
`->` two parallel spirals of the DNA that twist around the same centre
This form looks organized.

4. D, chromosome
`->` nucleic acids and protein found in the nucleus of most living cells which main role is to carry genetic information in the form of genes
`->` chromosome is a condensed form of chromatin, found only during cell division
This form looks organized.
