AZT is a reverse transcriptase inhibitor. How does this drug prevent the replication of a retrovirus
Artemon [7]

Answer:

AZT is a thymidine analog

Explanation:

Azidothymidine (AZT) is an antiviral drug used for the treatment of the Human immunodeficiency virus infection (HIV/AIDS) by preventing the transmission of HIV from infected cells. AZT is capable of suppressing the activity of the enzyme reverse transcriptase of the retroviral HIV genome, which enables it to copy RNA into DNA. In infected cells, this double-stranded DNA is integrated into the host genome which is then instructed to produce identical HIV copies. AZT is a thymidine analog that is incorporated into DNA and thus interferes with DNA synthesis, thereby inhibiting cell proliferation.

Determine the ionic characteristics of this element. calcium
Trava [24]
Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate.[5] Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis.

A student needs to prepare 250 mL of a 0.550 M aqueous solution of sucrose, C 12 H 22 O 11 ( aq ) , which is used frequently in
Grace [21]

Answer:

Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.

Explanation:

You need to prepare 250. mL of a 0.550 M aqueous solution of sucrose, C12H22O11 (aq),

which is used frequently in biological experiments.

Based on your answer above, what is the value of x?

Solution:

A 0.550 M aqueous solution contains 0.550 mole of sucrose per liter of solution.

250 ml = 0.250 liter

Thus a 0.250 liter of a 0.550 M aqueous solution of sucrose contains 0.250 * 0.550 = 0.1375 mole of sucrose

Recall:

Mass = number of moles * mass of 1 mole

mass of 1 mole of C12H22O11

= 12(12) + 1(22) + 16(11)

= 144 + 22 + 176

= 342 grams

Mass = 0.1375 * 342 = 47.025 grams of sucrose.

Dissolve 47.025 grams of sucrose in enough water to produce 250 ml of solution.
