These are the determiners of hereditary characteristics.*1 pointgenesDNAchromosomescell
Solution
The determiners of hereditary characteristics are genes, DNA, and chromosomes.
-
Genes: These are the basic physical and functional units of heredity. They are made up of DNA and act as instructions to make molecules called proteins.
-
DNA: This is the molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms and many viruses.
-
Chromosomes: These are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of DNA, which contains the organism's genes.
Cells are not determiners of hereditary characteristics, but they contain the nucleus where the chromosomes and DNA are located.
