They interact with light to absorb only certain wavelengths, pigments are useful to plants and other Autotrophs, organisms which makes their own food using photosynthesis. in plants,algae,and Cyanobacteria, pigments are the means by which energy of sunlight is captured by photosynthesis.
The complementary DNA sequence for CTG GAA CTA is GAC CTT GAT. This is explained by the default base pairing of adenine (A) to thymine (T) and guanine (G) to cytosine (C) in double stranded DNA. This base paring is significant in DNA replication as well as in transcription of DNA but with the thymine (T) replaced by uracil (U) in RNA.
