The mrna is at the <u>third position (3’ letter) </u>wobble base of the triplet codon.
- The third nucleotide in a codon is referred to as the wobble position. There are two main properties of this nucleotide:
- The cognate tRNA's binding to a codon in an mRNA is substantially more "looser" in the codon's third position.
- The third codon position can now accommodate a variety of non-Watson-Crick base pairings.
- The 5' end of the codon is where the tRNA anticodon and mRNA codon are paired.
- The precise base pairing of the third place is less important once the first two positions have been paired.
- It "wobbles" because the third (5') base of the anticodon can often mate with either the purine or pyrimidine pair in the codon, depending on the situation.

The protons are pumped across the inner mitochondrial membrane from the inner matrix to the intermembrane space by the energy employed in the electron transport chain, creating a significant gradient in the hydrogen concentration. When it was discovered, this process was known as chemiosmosis.
<h3>The inner membrane is what?</h3>
The inner or cytoplasmic membrane controls the flow of nutrients, metabolites, macromolecules, and information into and out of the cytoplasm and preserves the proton motive force necessary for energy storage. It is impermeable to polar molecules.
<h3>What use does the intermembrane serve?</h3>
Proteins that are essential for mitochondrial energetics and apoptosis are found in the intermembrane region between the outer and inner membranes (process of programmed cell death). The inner membrane is significantly less permeable to ions and molecules than the outer membrane.

The answer should be C, Sudan red solution.
Sudan red solution dissolves in lipids, which can show a color of orange/red if lipid is present.
On the other hand, Biuret solution/reagent is used to test for proteins, and it'll show a color or purple if protein is present.
Iodine solution is used to test for the presence of starch, and it'll show a blue black color if starch is present.
And lastly, Benedict's solution is used to test for reducing sugars, and it'll show a brick red color (or green as small amounts) if reducing sugars are present after heating under boiling water bath.
