Answer:
Nitrogen 15, N15 isotope,
Explanation:
Generally Nitrogen has two isotopes N14 and N15. The N14 has 7 protons and 7 neutrons with the atomic mass of 28( n+p). However the N15 has 7 protons and 8 neutrons.Since Neutrons are heavier than protons and constituted greater percentage of the atomic mass of an element the N15 isotope is heavier than the N14 isotope.
Therefore, Ammonium chloride solution containing the labeled heavier N15 was initially added to the bacterial growing medium; so that the bacterial can use it to make their DNA, and divided manytimes so that N15 isotopes is fully incorporated Therefore the DNA strands which incorporated this will be heavier,(old) and easier to segregate to the lower band during centrifugation , for identification compare to the newer lighter ones.
<u>Thus the parent( </u><u>heavy/old</u><u>) containing DNA N15 and( New/light) in the daughter DNA N14 strands can easily be separated for identification during semi- conservative replication.</u>
Because the climate determains the name and class of it. Say tundra. Its cold, gloomy snowy etc. Those are the characterists AND climate>
Answer:
it is examining the lipid level of the cells
Explanation:
The general procedure includes: 1) the isolation of the DNA from an evidence sample containing DNA of unknown origin, and generally at a later time, the isolation of DNA from a sample (e.g., blood) from a known individual; 2) the processing of the DNA so that test results may be obtained; 3) the determination of the ...
