Scientists realized each person's dna is different in 1985.
true or false

The statement is false

Explanation

the statement is wrong because the structure of DNA was discovered in 1953 by  James Watson and Francis Crick and they explained it very well. till 1985 everything about the structure of DNA was very well known and the scientist knew that the DNA of each person differs from each other.

haploid cells;

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
