Ans.

In a cell, nucleus can be seen by a simple compound microscope, while DNA molecules cannot be seen under a compound microscope. This is because, DNA molecules are too small and these molecules are dispersed in nucleus in less compact state.  

During DNA extraction, DNA is removed and purified from the cells by cell lysis. The extracted DNA is precipitated by ethanol that makes DNA molecules to clump together, makes it more condensed and DNA molecules become visible.

What advantages or disadvantages would you expect to be associated with knowing your own I Q
Setler [38]

Answer:

I can't think of any advantages to knowing your score.

Disadvantages of knowing your score - You're most likely to be average statistically...but does that matter? It doesn't tell you what you can or can't do, how successful you'll be, or what you'll face in the future. The total IQ score isn't really informative regarding almost anything. The exam is frequently used in clinical settings to assess areas of disability, competency, and so on...

(My opinion) :)))))

Independent assortment of chromosomes is a result of _____.
Ann [662]

Answer:

the "second law of Mendel", or principle of independent distribution, states that during the formation of gametes, each pair of alleles segregates independently of the other pairs.

Explanation:

Mendel's second Law is also known as the Law of Segregation, also as the Law of Equitable Separation, and also as the Law of Disjunction of the Alleles. This Second Law of Mendel is fulfilled in the second filial generation, that is to say, from the parents to the first generation, the First Law of Mendel is fulfilled, and after the children of the first generation this Second Law of Mendel is fulfilled.

This 2nd Law of Mendel, speaks of the separation of the alleles in each of the crossing between the members of the first generation, who would now become parental of the second generation, for the formation of a new child gamete with certain characteristics.

Since each allele is separated to constitute features that do not belong to the first filial generation, but to that of the parents. That is to say that many of the most obvious features in the recessive allele would be present when a generation leaps. All this in relative proportion to the number of individuals in the second subsidiary generation.

What might happen to a cell if it was missing some chromosomes?
qwelly [4]

Answer:

The phenomenon of unequal separation in meiosis is called nondisjunction. If nondisjunction causes a missing chromosome in a haploid gamete, the diploid zygote it forms with another gamete willcontain only one copy of that chromosome from the other parent, a condition known as monosomy.

Hope it helped
