It is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand.
- Deoxyribonucleic acid (DNA) is a biological molecule with two strands. Each strand is made up of a sequence of nucleotides. The DNA nucleotides are Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).
- In a DNA molecule, Adenine forms an hydrogen bond with Thymine i.e. A-T, while Guanine forms an hydrogen bond with Cytosine i.e. G-C.
- Therefore, it is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand. For example, a strand with ATGCGTACGAT will form the following sequence: TACGCATGCTA

B) Diploid - Only Gametes are Haploid. Every other cells are somatic cells which are diploid. They contain 46 chromosomes rather than 23 that the haploid carry. Neurons and glial cells make up of the brain and that makes up the nervous tissue. Just remember Gametes (sex cells) are the only cells that are haploids.
I looked it up and got energy not sure though
