quizlet chromosomes are composed of: please choose the correct answer from the following choices, and then select the submit ans

Anna11 [10]

Chromosomes are composed of deoxyribonucleic acid (DNA) mole

There are mainly two molecules that function as genetic material in living organisms.

These are ribonucleic acid(RNA) and deoxyribonucleic acid(DNA).

The organisms having DNA as genetic material require packaging of DNA as it is a long polymer of deoxyribonucleotides.

In the case of human beings, the length of DNA in a cell is approximately 2.2 meters which is very large as compared to the size of the nucleus( approximately 10^-6 meters).

So, the DNA has to be made compact for it to be present inside the nucleus of a cell.

Therefore, the DNA present inside the nucleus of a cell undergoes coiling and compaction through several stages before finally becoming a chromosome, which is shown in the adjoining diagram.

Thus, chromosomes are composed of deoxyribonucleic acid (DNA) molecules.

1) Speed = distance / time
s = 60 / 2
s = 30 km/h

In short, Your Answer would be Option B

2) Speed = distance / time
s = 25/4
s = 6.25 km/h

In short, Your Answer would be Option B
[ Direction not needed as it is speed not velocity ]

Hope this helps!
