It is possible for identical twins to have identical DNA, but very often that is not the case.
yes if the 2 people are identicle twins
Not even identical twins have the same DNA--although theirs would be far closer than anyone else's. DNA changes over time. Odds of two siblings having the same DNA who did not split from the same zygote are vanishingly small. If the current population of the earth was your sister, it is unlikely another person would have DNA close enough to yours they could be mistaken for your identical twin. The odds of two unrelated people sharing the same DNA is substantially smaller yet.
It is not possible because they are not in the same family. Can only mix DNA in ones family.
It depends... if you mix your DNA with a giraffe, it could be possible.
NO
With the same last name it's possible, but you could be related to people who don't share a last name with you. I guess the only way to truly know is through DNA testing.
I think this is related... No two people on earth can have the same DNA (genetics) so they wont be the same although they will be simalar though it is possiable to distinguish brother from sister, mother from daughter etc.
Variations in gene expression, environmental factors, and lifestyles can all contribute to differences in individuals with the same genome. Epigenetic modifications, such as DNA methylation and histone modification, can also play a role in gene expression. Additionally, random mutations can accumulate over time, leading to genetic diversity between individuals with the same genome.
Maybe, I mean they could evolve to become these pigs with wings, so anything's possible. Or, they could not evolve and have avian DNA put into their DNA, it could happen. But we don't know for sure if they will, but anything's possible
Yes, it is possible for two people to have different DNA and still produce the same amino acid. This is due to the redundancy in the genetic code, where multiple codons (sequences of three nucleotides) can code for the same amino acid. Variations in DNA may lead to different codons being used, but they can still result in the same amino acid being synthesized during protein translation. Thus, despite genetic differences, the outcome in terms of amino acid production can be the same.
Yes. Within a single person, all of the somatic cells have the same nuclear genomic DNA; it does not matter if you compare DNA from a cheek cell to a liver cell.
that no two people have the exact same DNA
