Explanation: A simple way to remember the is by PROkaryotic has NO nucleus. (Pro-no)
EUkaryotic has a nucleus.
(Eu- sound like you, you have cells and they have a nucleus.)
Excitation-contraction coupling refers to the series of events that begins with the excitation of the sarcolemma in response to stimulation by a neurotransmitter, and results in the release of calcium ions from the sarcoplasmic reticulum.
Hence, option D is the 1st process that starts the excitation-contraction coupling.
The chart very nicely lays out the amino acid each codon corresponds to. You're looking for "trp" in the chart, which only appears once, beside the UGG codon. Therefore, only one codon codes for tryptophan.
The component of DNA that became the source of this information is : the base
The backbone of our DNA carries four type of bases which each could contain unique sequences
These unique sequences of the four bases are the one that encodes the information.
Answer:
aceptable value is directly accessed where as experimental value is not coinfermed.
