"Nucleic acid was isolated by lysing cells in detergent, guanidine isothiocyanate, and DNAse, followed by extraction in an acid
Romashka [77]

Answer:

RNA

Explanation:

The nucleic isolated was quantified by 2 types of fluorescent dyes, which binds only to specific type of nucleic acid. You can find the information on the specificity of dyes on your labsheet or dye supplier's website. For our dyes, however:

  • SyBr Green II only emits fluorescent light when it binds to RNA or Single Strand DNA
  • PicoGreen only fluoresce when bound to Double Strand DNA

With these information, we know that our nucleic acid is either single strand DNA or RNA, however, it is also mentioned that

"Nucleic acid was isolated by lysing cells in detergent, guanidine isothiocyanate, and DNAse"

DNAse, which is an enzyme that breaks down DNA, destroys any extracted DNA during the process, thus, the only possible nucleic acid we have isolated is RNA

Calculate the number of different atoms in 0.2 mol ethene​
muminat

Answer:

1.204 × 10²³

Explanation:

The number of atoms in a mole is always 6.022 × 10²³, known as Avogadro's number or Avogadro's constant.

To convert moles to atoms, multiply the molar amount by Avogadro's number.

(6.022 × 10²³) × 0.2

         = 1.204 × 10²³
