Histones are proteins that control gene function by attaching salt links to exterior regions of DNA. Argentines is an amino acid whose side chain is often found on the exterior of histones

A chromosome's structural support is provided by a protein called a histone. Long DNA molecules found on each chromosome must fit into the cell nucleus. This is accomplished by the DNA wrapping around histone protein complexes, giving the chromosome a more compact form.

The eight-protein complex known as a histone octamer is what makes up the nucleosome core particle. Each of the four main histone proteins is present in two copies in this structure (H2A, H2B, H3 and H4). When a tetramer, which has two copies of both H3 and H4, interacts with two H2A/H2B dimers, the octamer forms.

How many seconds are in a 5.5 ms
deff fn [24]

Answer:

0.0055 seconds

Explanation:

To answer this question you need to know the equivalence:

1 second (s) = 5.5 (miliseconds) (ms)

Then you use the conversion factor:

-Put the value given and the units:

5.5ms

- Put in the denominator the equivalence with the same units:

5.5ms*\frac{}{1000ms}

- Put in the numerator the unit at which you want to convert the value given:

5.5ms*\frac{1s}{1000ms}

- Then multiply and divide the quantities:

5.5ms*\frac{1s}{1000ms}=0.0055 s

Note that the same units in numerator and denominator are cancelled.

Suppose you decide to define your own temperature scale using the freezing point (13 degrees C) and boiling point (360 degrees C
podryga [215]
M.P of  oleic acid = 13 deg C 
<span>B.Pof  oleic acid = 360 deg C </span>



<span>(360 - 13) / 100 = 3.47 </span>
<span>So 1 deg O = 3.47 deg C </span>

<span>The scale do not start at 0 deg C, it starts at 13 deg C. So to convert deg C to deg O,
 subtract 13 then divide by 3.47 </span>

<span>deg O = (deg C - 13) / 3.47 </span>

<span>convert  O to C multiply by 3.47 then add 13 </span>

<span>deg C = (deg O x 3.47) + 13 </span>


<span>convert 0 deg C to deg O </span>
<span>deg O = (0 deg C - 13) / 3.47 </span>
<span>= - 3.75 deg O</span>

Which of these chemical formulas represents both an element and a molecule?
inna [77]
O2.

Because it is only made up of one type of element it is an element. Howevern there is more than one oxygen atom because oxygen cannot exist as a single atom, therefore making it a molecule as well.

A sample of gas occupies a volume of 64.0 mL . As it expands, it does 137.1 J of work on its surroundings at a constant pressure
stiks02 [169]

Answer : The final volume of the gas is, 34.8 L

Explanation :

Formula used :

w=p\times (V_2-V_1)

where,

w = work done = 137.1 J = 35.8 L.atm      (1 L.atm = 101.3 J)

p = external pressure = 783 torr = 1.03 atm    (1 atm = 760 torr)

V_2 = final volume = ?

V_1 = initial volume = 64.0 mL = 0.0640 L      (1 L = 1000 mL)

Now put all the given values in the above formula, we get:

35.8L.atm=1.03atm\times (V_2-0.0640L)

V_2=34.8L

Thus, the final volume of the gas is, 34.8 L
