The possible products of a PCR experiment which carry a single stranded disruption in the target DNA sequence, which is present in only one copy in the starting sample. Concept introduction: The polymeric chain reaction (PCR) is a technique in which amplification of a specific DNA segment occurs quickly and accurately. In this technique, a DNA sample is separated by using restriction enzymes into single strands. Then these strands are incubated with DNA polymerase such as Taq polymerase, two primers, and deoxynucleotides triphosphate (dNTPs). A PCR cycle consists of three steps such as strand separation, the hybridization of primers, and the extension of by DNA synthesis.

Question

At a pH equal to the isoelectric point (pl) of alanine, the net charge of alanine is zero. Two structures can be drawn that have a net charge of zero, but the predominant form of alanine at its pl is zwitterionic. CH3 H,N CH3 ** H¸N-C H Zwitterionic H Uncharged OH Select statements that explain why alanine is predominantly zwitterionic at its pl. pk of alanine's amino group is more than its pl. pk of alanine's carboxyl group is more than its pl. PK of alanine's carboxyl group is less than its pl. pk of alanine's amino group is less than its pl. Correct Answer What fraction of alanine is in the completely uncharged form at its pl? 1 in 2.2 × 107 1 in 1.6 × 10² 1 in 4680 1 in 9460

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.

How does a voltage-gated sodium channel work? Specifically, how and why does a change in voltage trigger their opening? Please be detailed

When sodium ions enter a neuron during depolarization, they trigger the opening of additional voltage-gated sodium channels nearby, creating a positive feedback loop where the influx of sodium ions further depolarizes the membrane, causing even more sodium channels to open and allowing more sodium ions to enter the cell, thus sustaining the depolarization process until the action potential peaks. But how and why exactly does the influx of sodium ions trigger more sodium channels to let in more sodium? Please explain
