Probably another DNA molecule. But even then there will be monior differences. So I suggest there is nothing that is the same shape.
The parts of DNA molecule are nucleotide, bases, and the hydrogen bonds. The nucleotide contains a pentose sugar, phosphate group, and nitrogenous bases. Bases contain pyrimidine and purine and the hydrogen bonds holds the chains of nucleotides.
The DNA molecule consists of two strands of DNA nucleotides which coil, forming a twisted ladder shape called a double helix. The sides of the "ladder" are composed of alternating deoxyribose sugar molecules and phosphate groups. The rungs of the "ladder" are the pairs of nitrogen bases. Refer to the related link for an illustration.
something like very tiny ball
Yes, it's a molecule. Water is H2O.
DNA is a type of nucleic acid.
A covalent bond.
glucose and proteins
Two hydrogen atoms and one oxygen atom
They both contain 2 atoms?
3
A molecule because there are 2 oxygen atoms bonded.
