Silent mutation
Silent mutations are DNA mutations that do not result in a change to the amino acid sequence of a protein. This kind of mutation may occur in a noncoding region (outside of a gene or within an intron), or they may occur within an exon in a manner that does not alter ...

Classification of Diatoms
How are diatoms classified? Selections from Ernst Haeckel's 1904 Kunstformen der Natur (Artforms of Nature), showing pennate (left) and centric (right) frustules. The classification of heterokonts is still unsettled, and they may be treated as a division (or phylum), kingdom, or something inbetween ...

Diatoms
Diatoms (Greek: διά (dia) = "through" τέμνειν (temnein) = "to cut", i.e., "cut in half") are a major group of eukaryotic algae, and are one of the most common types of phytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons ...

DNA
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions of an organism. These genetic instructions are used in the development and functioning of all known living organisms and some viruses. DNA Stores Information The main role of DNA molecules is the longterm storage ...

Point mutation
point mutation, or substitution, is a type of mutation that causes the replacement of a single base nucleotide with another nucleotide. Often the term point mutation also includes insertions or deletions of a single base pair (which have more of an adverse effect on the synthesized ...

Mutation
biology, a mutation is a change to the nucleotide sequence of the genetic material within an organism. What causes mutations? Mutations can be caused by: copying errors in the genetic material during cell division, exposure to ultraviolet or ionizing radiation, chemical mutagens, or viruses ...
