Single stranded___ molecules translate he code for making protein
Radda [10]

Answer:

RNA

Explanation:

Central dogma is the process of the formation of protein from the sequence of nucleotide on DNA. It consists of two further processes Transcription and translation.

During Transcription, the information from the DNA sequence is transcripted in a sequence of RNA, that is single stranded and contains Uracil instead of Thymine.  During Translation, the information from the RNA sequence is translated into a sequence of amino-acid, and a protein.

Hope it helps!

At 25 °C, only 0.0990 mol of the generic salt AB3 is soluble in 1.00 L of water. What is the Ksp of the salt at 25 °C? AB3(s)↽−−
maksim [4K]

Answer:

Ksp=2.59x10^{-3}

Explanation:

Hello,

In this case, given the 0.0990 moles of the salt are soluble in 1.00 L of water only, we can infer that the molar solubility is 0.099 M. Next, since the dissociation of the salt is:

AB_3\rightleftharpoons A^{3+}+3B^-

The concentrations of the A and B ions in the solution are:

[A]=0.099 \frac{molAB_3}{L}*\frac{1molA}{1molAB_3}  =0.0099M

[B]=0.099 \frac{molAB_3}{L}*\frac{3molB}{1molAB_3}  =0.000.297M

Then, as the solubility product is defined as:

Ksp=[A][B]^3

Due to the given dissociation, it turns out:

Ksp=[0.099M][0.297M]^3\\\\Ksp=2.59x10^{-3}

Regards.

In a solution the hydroxide ion concentration is 1 ✕ 10-12 M. What is the pH of the solution?
Deffense [45]

Answer:

pH = 2 and pOH = 12

Explanation:

Given [OH⁻] = 1 x 10⁻¹²M

pOH = -log[OH⁻] = -log(1 x 10⁻¹²) = - ( -12 ) = 12

pH + pOH = 14 => pH = 14 - pOH = 14 - 12 = 2
