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.
An organic polymer.
DNA
Probably another DNA molecule. But even then there will be monior differences. So I suggest there is nothing that is the same shape.
phosphates and amino acids
Dna
Yes, DNA has the same basic structure in all organisms. It is composed of nucleotides that include a sugar-phosphate backbone and four nitrogenous bases (adenine, thymine, cytosine, and guanine). The sequence of these bases varies between organisms, giving rise to genetic diversity.

DNA (deoxyribonucleic acid) is the compound that has the same basic structure in all eukaryotic organisms and contains genetic information in the form of genes. DNA is made up of two long chains of nucleotides that form a double helix structure, encoding the instructions necessary for the development, functioning, and reproduction of living organisms.
The most basic DNA structure is a double helix composed of two complementary strands of nucleotides held together by hydrogen bonds. Each strand consists of a sugar-phosphate backbone with nitrogenous bases (adenine, thymine, cytosine, and guanine) attached to the sugars.
No. DNA is not a vestigial structure as it has not ceased to function
The structure of DNA has been a constant structure since the beginning of creation.
The pH of DNA is typically around 7.5 to 8.0, which is slightly basic. DNA is a negatively charged molecule due to the phosphate groups in its structure, which can affect its interactions with other molecules in different pH environments.
