Isotopes are different versions of an element or different versions of a certain kind of atom. In order for an atom to be an isotope, it must have the same number of protons because the protons determine what kind of element it is. Also, there must be a different number of neutrons in the core the atom.
Answer:
The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Explanation:
Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.
In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.
The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.
Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.
Answer;
The above statement is true
One type of personal health monitor measures the amount of time you spend in REM sleep.
Explanation;
-Fitness tracker or monitors have the ability to monitor or track the shut-eye during sleep.
-These trackers all continuously monitor the movements of the eye during sleep and also assess sleep-wake cycles to ascertain whether an individual is in deep or light sleep.
-Some of the trackers incorporates heart rate data to get a better sense of how deep one is into their sleep.
