I found this on the web: In biochemistry, chemosynthesis is the biological conversion of one or more carbon molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic (e.g. hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis
hope this helps u out
During replication, molecule DNA is copied into new identical molecule DNA. According to the complementary rule, adenine will always bind thymine and vice versa while guanine will always bind cytosine and vice versa. So, if the pairing of bases is perfect during the replication, the offspring will have the same sequence of bases in molecule DNA their parents have.
Sunlight or artificial light is a source of glare.
