The branch of Biology that focuses on heredity and dna is called "genetics", from greek γένεσις génesis, "origin" and icos "refering to something". All living things posses DNA, and, excepting primordial cells, every single organism we know have been formed of a previous one by the processes of DNA metabolism: replication, translation and coding.
Genetics; and Biochemistry examines and discovers the roots [origins] of both of these.

DNA
DNA controls the cell's functions and heredity.
Yes and no. Some of the heredity material comes from the parents.
DNA
Traits are passed by DNA.
Heredity is part of your DNA and how it is structured. You have a combination of both of your parents DNA because you are copied. That is why you look like your parents
DNA
They have DNA as heridity material.They have circular DNA.
DNA determines what characteristics the cell would have. When a cell divides, the chromosomes containing DNA are split in half. Half of the DNA from the original cell is carried by each of the resulting cells.
DNA of the parents! Heredity means it is passed on through the biological family.
