A single-nucleotide polymorphism (SNP, pronounced snip) is a DNA sequence variation occurring when a single nucleotide - A, T, C, or G - in the genome (or other shared sequence) differs between members of a species or paired chromosomes in an individual. For example, two sequenced DNA fragments from different individuals, AAGCCTA to AAGCTTA, contain a difference in a single nucleotide. In this case we say that there are two alleles: C and T. Almost all common SNPs have only two alleles.
Within a population, SNPs can be assigned a minor allele frequency - the lowest allele frequency at a locus that is observed in a particular population. This is simply the lesser of the two allele frequencies for single-nucleotide polymorphisms. There are variations between human populations, so a SNP allele that is common in one geographical or ethnic group may be much rarer in another.
It is important for nucleotide bases to stay in the same position because they provide the genetic information necessary for the functioning of an organism. The arrangement of the bases in the DNA molecule determines the sequence of amino acids in proteins, which play crucial roles in cellular processes. Any change in the position of the nucleotide bases can lead to disruptions in these processes, potentially causing genetic disorders or functional abnormalities.
No. Your mass will stay the same. Your weight, however, will change in direct proportion to each planet's gravity.
No it doesnt change. The chromosomes will stay at the same number unless there is a mutation through the process of meiosis.
It is a physical change, the substance stay the same elements before and after the change, this is the same for all states of matter changes (melting, freezing, evaporating, condensing, and sublamation)
No liquids and solids do not change size the volume, mass,density, and weight stay the same they just change shape.

The parts of an experiment that stay the same.
the angles stay the same but the lenght of the sides change.
The ohms will usually stay the same unless the Amps are somehow effecting the temperature. The Amps will always change with the volts.
No, beacuse they stay at the same place.
No. If one substance does not change into another, it is not a chemical change.
Yes. Molecules remain the same.
It would remain the same
no because the wax will always stay the same. it is a physical change
Of course the rental history stays the same. You might be able to change the name, but your the same person.
Roses are perennial therefore they change during the year.
The actual atmosphere itself does not change with elevation, but the atmospheric pressure does.
