What reason led kary mullis to dearch for a dna polymerase enzyme?

1 answer:

8 0

The need for a polymerase that wouldn't denature at high temperature. Obviously, organisms that live in hot springs and the like will have adapted enzymes that can survive at these temperatures.

The fixed pattern of changes in membrane potential during an action potential is coordinated by the sequential opening and closi

baherus [9]

<h2>Na-K channels</h2>

Explanation:

Brief sequential change in the membrane potential of excitable cells after stimulus is called action potential whereas membrane potential represent charge difference across the membrane
In a typical neuron cell, membrane potential of cytoplasm is negative at rest and hence called resting membrane potential
Resting membrane potential of excitable cells is established by Na+ K+ pump and maintained by K+ leaky channels at rest
Phases of action potential includes: depolarization, repolarization, hyperpolarization and resting membrane potential
Depolarization starts when a threshold stimulus is applied on a neuron when via Na+ mechanically operated channels that trigger action potential
Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels, voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive
Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channel

If an albino (aa) mates with a person homozygous for normal pigment (aa), select one:

geniusboy [140]

One parent is an albino with the genotype aa (recessive homozygous), while another parent has genotype AA (dominant homozygous). If they mate:

Parents aa x AA F1 generation: Aa Aa Aa Aa 
This means that c. all offspring are normal.
All of them are carriers of the albino allele (a), but albinism is expressed only when there are two recessive alleles.
