sister chromatids before crossing over
Both chloroplasts and mitochondria have their own sets of chromosomes composed of DNA.
Genes are generally composed if DNA fragments.
The question itself is not clear. Two cells that have just divided will have the MOST similar DNA. If we are talking about whole organisms or individuals, then clones would have the most similar DNA, similarly identical twins would have near identical DNA. Siblings have very similar DNA but not identical of course.
Is composed of long similar nucleotide sequence that, as transposons, became scattered throughout the genome.
Both DNA and RNA are composed of nucleotides containing a five carbon sugar, a phosphate group, and one of four nitrogen bases.
Genes are composed of DNA
because everyone's DNA is different
organelle composed of double membrane acts as a storehouse for most of a cell DNA
A DNA molecule is composed of long chains of DNA nucleotides.
Genes are composed of DNA. Chromosomes are composed of DNA and proteins. Genes are the sections of DNA which code for a functional product (such as a protein). Chromosomes are the compact, tightly-coiled form of DNA. These appear before the cell undergoes division/replication.
Chimpanzees and bonobos are the animals most genetically similar to humans, sharing about 98 of our DNA.
No though DNA is in chromosomes DNA stands for Deoxyribonucleic acid and those acids are composed in DNA
