How much DNA can be extracted from an onion

Chemistry
1 answer:
konstantin123 [22]3 years ago
4 0
Since the onion (Allium cepa) is a diploid organism having a haploid genome size of 15.9 Gb, it has 4.9x as much DNA as does a human genome (3.2 Gb). Other species in the genus Allium vary hugely in DNA content without changing their ploidy.

B. Why is this number called a "mass” number?
deff fn [24]

<u>Answer:</u>

The mass of the atom depends on the sub atomic particles present in the nucleus of an atom.

That is, the protons and the neutrons.

Electrons are present around the nucleus and the mass is negligible since its mass is very very less.

<em>mass of a proton = 1.673\times10^{-27} kg</em>

<em>mass of a neutron = 1.675 \times 10^{-27} kg</em>

<em>mass of an electron = 9.109 \times 10^{-31} kg</em>

Mass number represents the mass of one particular isotope and it is a whole number for example, _6 C^{13}

Mass number is 13 and atomic number is 6 for the carbon isotope C-13.  

Atomic mass is different from mass number and it is a fraction since it is the average atomic mass of all the isotopes of an atom.

Atomic mass of C is 12.011 amu which we see in the periodic table is the average atomic mass of isotopes C-12, C-13 and C-14.

PLEASE HELP WITH #1 AND #2 ASAP!! PLEASE
Grace [21]
1. Since the track is extended outwards from lane one, the other lanes will be a longer distance then lane one. So the runners in the lanes (2,3,4,5,6,7,8) will start ahead of the runner in lane one so they all run the same distance. 2. The displacement of runner 1 would be that since they are farther back then they will have to run top speed in order to catch up to the other runners, especially runner 8 since it seems like they are so far ahead. This isn’t necessarily the same for all the runners because runner 1 is the farthest back and is at a disadvantage since they are in the inner lane and not the outer lane. I reallyyyy hope this helped :)
