A lot of DNA is structural and doesn't pertain to any genetics while it only takes a small change to change something big. DNA mainly uses 4 different chemicals to change itself, not giving a lot of variety. Most animals share around 98% of the same dna with each other. Humans share 50% of their DNA with a banana. Pretty much everything shares the same double helix design as well. So a lot of genetic code looks similar.
Because Thymine is "replaced" with Uracil, the corresponding RNA Code for AAT would be UUA.
Answer:
the change of DNA structure is a mutation
Explanation:
the molecule spreads
Bacteria: are single-celled microscopic organisms that are characterized by the presence of incipient nucleus and few membrane-less cell organelles.
Fungi: are eukaryotes that are characterized by the presence of chitin in the cell wall.
Cell Type: All bacteria are prokaryotes. All fungi are eukaryotes.
Answer:
Darwin's greatest contribution to science is that he completed the Copernican Revolution by drawing out for biology the notion of nature as a system of matter in motion governed by natural laws. With Darwin's discovery of natural selection, the origin and adaptations of organisms were brought into the realm of science
