Answer:
A) identify the N-terminal amino acid of a polypeptide
Explanation:
Edman degradation is a series of chemical reactions that enables the stepwise cleavage of the amino-terminal residue from a peptide/protein. This method sequentially removes N-terminal residues without disrupting peptide bonds between other amino acid residues, thereby obtaining the amino acid sequences from the target peptide/protein. Edman degradation can be defined as a cyclic method in which each residue is cleaved off from the amino-terminal end of the peptide/protein and then identified by reverse-phase chromatography, which is a technique used to separate peptides/proteins on the basis of their hydrophobicity.
That would be 1/16 which is 6.25%. The offspring have to be rryy.
There are 2 ways of thinking about this and other dihybrid crosses
—> the ratio of different genotypes is (9:3:3:1) for a dihybrid cross so the probability of wrinkled and green offspring is 1/16 (9+3+3+1=16)
—-> we can think of them as 2 monohybrid crosses. One RrxRr and one YyxYy. The probability of getting wrinkled(rr) is 1/4. The probability of getting green(yy) is 1/4. So the probability of wrinkled AND green is 1/4*1/4=1/16
Answer:
d. more permeable to sodium ions.
Explanation:
The binding of Acetylcholine with the receptors at motor end plate facilitate membrane permeability to sodium ions therefore opening of voltage gated channels for sodium ions.
Sodium ions diffused into the synapse of post synaptic neuron at the neuromuscular junction.
If the stimulus is up to threshold levels; more chemical(neurotransmitter) gated sodium channels opens, and sodium ions move into the synapse to depolarize the membrane with reversal of charges to generate action potential.
The continuous binding of Acetycholine , leads to permanent opening of sodium ions,and over excitation from depolarization. Acetycholinesterase enzymes breakdown Acetycholine to choline and Acetyl Co -A. These are recycle back to Acetycholiine
I'd say false...
good luck!
