All living beings reproduce themselves

Basic concept - reproduction

characterization

Creature are able to reproduce and pass on genetic information. The ability of DNA to duplicate identically forms the basis for reproduction.

The basic concept can, for example, be demonstrated using the following content:

  • Recombination and diversity: The recombination and recombination of genes (e.g. sexual reproduction) results in genetic and phenotypic diversity as a prerequisite for evolution.
  • Replication and Mutation: When the DNA is replicated as the basis of all reproduction, the existing DNA strands serve as templates for the synthesis of suitable new DNA strands. Mutations can occur during replication.
  • asexual reproduction /asexual reproduction: This type of reproduction results in identical cells / living beings, as the offspring only receive the genes of one parent. E.g. archaea, bacteria, algae, yeast, some fungi etc.
  • sexual reproduction / reproduction: This type of reproduction leads to variability as a recombination of the parents' genes takes place. Together with the random mutation, it is the basis for the evolution of living things.
