If the star is receding, the pattern moves to longer, redder wavelengths. This is called redshift. Edwin Hubble used the Doppler effect<span> to determine that the universe is expanding. ... This red shift indicates that stars are moving away from us and from each other.</span>
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

Explanation:
<span>The four main parts of a flower are: pistil, stamen, petals and sepals. The pistil is the female part of the flower, the stamen is the male part of the flower, the petals are the colourful parts of the flower while the sepals are the modified leaves which protect developing flower buds. The pistil is made up of the stigma, style and ovary while the stamen is made up of filament and anther.</span>
