To maintain the integrity of the genetic information, cells have evolved various DNA repair mechanisms. These mechanisms can detect and correct different types of DNA damage, such as base mismatches, ...

Although the DNA code from cell to cell is the same, there are many different types of cells within the body, each with a specific function. For example, the long, narrow muscle cell is designed ...

they discovered that the kDNA contained two different kinds of DNA (Laurent & Steinert 1970; Simpson & Da Silva 1971). What were these two types of structures? In electron micrographs of the ...

The authors wrote, “DNA analysis showed two distinctly different types of results; the mitochondrial DNA was unambiguously human, while the nuclear DNA was shown to harbor novel structure and sequence ...

This DNA is wrapped around proteins to form chromatin, which exists in two main forms: euchromatin ... "How these two types of chromatin are organized and behave inside living cells is still ...
