Antiparallel Strands in DNA Molecule
DNA is composed of two strands that run antiparallel to each other. This means that one strand runs in the 5' to 3' direction, while the other runs in the 3' to 5' direction.
Base Pairing in DNA
In the DNA molecule, adenine always pairs with thymine, and guanine always pairs with cytosine. This complementary base pairing is crucial for maintaining the structure and function of DNA.
Base Composition Variation
The proportion of adenine in relation to thymine can vary between different organisms. For example, in humans, the amount of adenine is roughly equal to the amount of thymine. However, in other organisms, this ratio may be different.
Equal Amount of Purine and Pyrimidine
While the total amount of purine nucleotides (adenine and guanine) and pyrimidine nucleotides (cytosine and thymine) is usually equal in DNA, there can be slight variations due to mutations or other factors.
In conclusion, the DNA molecule consists of two antiparallel strands that run in opposite directions. The base composition of DNA can vary between organisms, but the complementary base pairing of adenine with thymine and guanine with cytosine remains constant.
