Chargaff's rule states that the amounts of guanine and cytosine are roughly the same, and the amounts of adenine and thymine are

roughly the same
Biology
1 answer:
Mazyrski [523]3 years ago
8 0

Answer:

True.

Explanation:

The Chargaff's rules indicate that in the DNA of all living organisms the amount of adenine (A) should be equal to the amount of thymine (T), while the amount of guanine (G) should be equal to the amount of cytosine (C). These rules were useful to describe the structure of  the double helix and also enable to describe base patterns that often are associated with specific gene regions (for example, promoter regions are rich in AT). Moreover, an imbalance in the 1:1 equilibrium ratio is associated with mutations that may cause diseases such as cancer.

How many grams are NaCl are required to prepare 200 mL of a 3.10 M solution?
rodikova [14]

The mass (in grams) of NaCl required to prepare the solution is 36.27 g

<h3>What is molarity?</h3>

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the mole of NaCl</h3>
  • Volume = 200 mL = 200 / 1000 = 0.2 L
  • Molarity = 3.1 M
  • Mole of NaCl =?

The mole of NaCl in the solution can be obtained as follow:

Molarity = mole / Volume

Cross multiply

Mole = Molarity x Volume

Mole of NaCl = 3.1 × 0.2

Mole of NaCl = 0.62 mole

<h3>How to determine the mass of NaCl </h3>

We can obtain the mass of NaCl needed to prepare the solution as follow:

  • Molar mass of NaCl = 58.5 g/mol
  • Mole of NaCl = 0.62 mole
  • Mass of NaCl = ?

Mole = mass / molar mass

Cross multiply

Mass = mole × molar mass

Mass of NaCl = 0.62 × 58.5

Mass of NaCl = 36.27 g
