nucleus or organelles)
eukaryotic cells - ANSWERare cells which have a membrane closed nucleus and
membrane-enclosed organelles
DNA is the basis of heritable information
The passing of DNA from one generation to another is the basis of -
ANSWERinheritance.
inheritance - ANSWERAcquisition of traits by transmission of DNA from parent to
offspring.
This process of transmitting the DNA to new generations is built into the functions of
reproduction.
DNA also provides the instructional methods that guide the
