tytärDNAmolekyyli

TytärDNAmolekyyli refers to a DNA molecule that is newly synthesized during DNA replication. When a cell prepares to divide, its DNA must be duplicated to ensure that each daughter cell receives a complete set of genetic information. This process, known as DNA replication, is semi-conservative. This means that each new DNA molecule consists of one original strand from the parent DNA molecule and one newly synthesized complementary strand.

The parental DNA double helix unwinds, and each strand serves as a template for the synthesis of a new strand. Enzymes like helicase separate the strands, and DNA polymerase then adds complementary nucleotides to build the new strands. The "tytärDNAmolekyyli" is the complete double helix formed after this process, containing one old and one new strand. This ensures genetic continuity from one generation of cells to the next. The accurate replication and distribution of these daughter DNA molecules are crucial for cell function and the inheritance of traits.
