What is the acronym for DNA??

1 answer:

5 0

The acronym 'DNA' stands for deoxyribonucleic acid.

DNA is used to 'code' the genetic makeup of all living organisms, and is found inside the nucleus of the cell(Eukaryotes) or just floating in the cytoplasm of the cell(Prokaryotes). DNA is made up of 4 different pairs of base molecules(nucleotides) that are slightly different from another. The similar molecule structure RNA(ribonucleic acid) differs from DNA in that RNA nucleotides are just slightly different from the nucleotides of DNA. This difference is that RNA nucleotides have a hydroxide group(OH) where the DNA nucleotides just have a hydrogen atom.
Because the DNA nucleotide doesn't have the hydroxide group it has one less oxygen than RNA nucleotides do. This is where DNA derives the prefix "deoxy-," meaning "without oxygen."
The prefix "ribo-" is given to molecules with a certain configuration of a set of 3 consecutive but not necessarily contiguous CHOH(asymmetric) groups.
The combined form "nucleo-" is used to imply something that has to do with the nucleus, such as the nucleus of a cell where DNA is stored in Eukaryotes.
And finally, the ending of the acronym: "acid." DNA is an acid because the 4 nucleotides each contain a phosphate group, which are acidic.

And thus, we get our answer: deoxyribonucleic acid, and the meaning:
deoxy-ribo-nucleic acid
(without oxygen) + (has 3 CHOH groups) + (in/of the nucleus) + (acidic)
Thus, DNA is a molecule is basically an acidic molecule residing in the nucleus with 3 CHOH groups and is missing oxygen atoms.

I know this isn't really what you're looking for, but honestly I had a great time doing a little research into the name!

Hope this explains it a little! c;

in which of the following aqueous solutions would you expect AgCl to have the HIGHEST solubility?a) Pure Waterb) 0.015 M NaClc)

kirill115 [55]

Answer:

Pure Water

Explanation:

The common ion effect describes the effect on equilibrium that occurs when a common ion (an ion that is already contained in the solution) is added to a solution. The common ion effect generally decreases solubility of a solute(Khan Academy).

NaCl, AgNO3, KCl, BaCl2 solutions all have a common ion with AgCl. As a result of this, AgCl will be much less soluble in these solvents than it is in pure water.

Therefore, AgCl will have the highest solubility in pure water compared to all the solutions listed above.

Drinking water may contain a low concentration of lead ion (Pb2 ) due to corrosion of old lead pipes. The EPA has determined tha

Lynna [10]

Answer:

3.861x10⁻⁹ mol Pb⁺²

Explanation:

We can define ppm as mg of Pb²⁺ per liter of water.

We calculate the mass of lead ion in 100 mL of water:

100.0 mL ⇒ 100.0 / 1000 = 0.100 L

0.100 L * 0.0080 ppm = 8x10⁻⁴ mg Pb⁺²

Now we convert mass of lead to moles, using its molar mass:

8x10⁻⁴ mg ⇒ 8x10⁻⁴ / 1000 = 8x10⁻⁷ g

8x10⁻⁷ g Pb²⁺ ÷ 207.2 g/mol = 3.861x10⁻⁹ mol Pb⁺²

A gas occupies 547 L at 331K. Find its volume at 376K. You must show all of your work to receive credit. Also, name the gas law

zysi [14]

621.4L

Explanation:

Given parameters:

Initial volume = 547L

Initial temperature = 331K

Final temperature = 376K

Unknown:

Final volume = ?

Solution:

The appropriate gas law to use is the Charles's law.

The Charles's law shows the relationship between the volume and temperature of a gas under constant pressure.

The law states that "The volume of a fixed of a gas varies directly as its absolute temperature if the pressure is constant".

Mathematically;

$\frac{V_{1} }{T_{1} } = \frac{V_{2} }{T_{2} }$

V₁ is the initial volume

T₁ is the initial temperature

V₂ is the final volume

T₂ is the final temperature

Since the unknown is the final volume, we make it the subject of the expression;

V₂ = $\frac{V_{1} }{T_{1} } x T_{2} = \frac{547}{331 } x 376$

V₂ = 621.4L

Given the reaction:

tino4ka555 [31]

4 moles of NaCl is produced from 2 moles of Na₂CrO₄.

Explanation:

Given reaction is

PbCl₂(aq) + Na₂CrO₄(aq)→ PbCrO₄(s) + 2 NaCl (aq)

It is the balanced equation which means that on both sides of the equation, number of atoms of each element are equal.

From the above balanced equation it says that molar ratio of Na₂CrO₄ to NaCl is 1 : 2.

That is 1 mole of Na₂CrO₄ produces 2 moles of NaCl, so the molar ratio is 1:2.

2 moles of Na₂CrO₄ produces 4 moles of NaCl.

So the molar ratio of Na₂CrO₄ to NaCl is 2: 4.
