There are 3 STOP codons in the genetic code - UAG, UAA, and UGA. These codons signal the end of the polypeptide chain during translation.
Answer:
Hydroxide concentration of the sample is 1.3x10⁻⁶M
Explanation:
The equilibrium constant of water, Kw, is:
H₂O(l) ⇄ H⁺(aq) + OH⁻(aq)
Kw is defined as:
Kw = 1.7x10⁻¹² = [H⁺] [OH⁻]
As the sample is of pure water, both H⁺ and OH⁻ ions have the same concentration because come from the same equilibrium, that is:
[H⁺] = [OH⁻]
We can write the Kw expression:
1.7x10⁻¹² = [OH⁻] [OH⁻]
1.7x10⁻¹² = [OH⁻]²
1.3x10⁻⁶M = [OH⁻]
<h3>Hydroxide concentration of the sample is 1.3x10⁻⁶M</h3>
Answer:
oxygen ion O2-

Answer:
![[Pt(NH_{3}_{2})Cl_{2}]](https://tex.z-dn.net/?f=%5BPt%28NH_%7B3%7D_%7B2%7D%29Cl_%7B2%7D%5D)
shows geometrical isomerism.
Explanation:
<u>Geometrical isomerism:</u>
<em>"Molecules having same molecular formula but the but difference in the arrangement of atoms."</em>
Cis and trans isomers are called geometrical isomers.
Among the given , shows geometrical isomerism.
The <em>cis </em>and <em>trans</em> forms of the are as follows.
