                     ANSWERING YOUR 
QUESTIONS RELATED TO 
THE DNA, DNA TEST, AND 
GENETIC.
EVERYONE IS TALKING ABOUT DNA 
TESTING AND GENES INHERITANCE AND 
ALL BUT WHAT IS THIS DNA AND GENE 
AND WHY DOES AFFECT OUR LIFE AND 
OUR CHILDREN’S LIFE. HERE ARE SOME 
ANSWERS TO THE FIVE BASIC QUESTIONS 
THAT POP UP IN YOUR MIND WHEN 
SOMEONE TALKS ABOUT DNA AND 
GENES.
WHAT IS DNA?
Deoxyribonucleic acid or ‘DNA’ in short, is the basic 
hereditary material in humans. It is a molecule that 
determines every function in your body from when you were 
an embryo till the day you die. It is made up of chemical 
bases which are joined together in two long coils intertwined 
in a spiral, that’s why DNA is also known to have a double-
helical structure.
WHAT ARE GENES?
Genes are made up of DNA. They are the basic and functional 
unit of heredity. Genes give the instruction to make 
proteins. Genes are present on chromosomes and they are 
transferred to offspring which depends on which chromosome 
end they are present on. These genes are passed from 
parents to their children. These genes determine the different 
characteristics like hair and eye color.
WHAT ARE CHROMOSOMES?
Chromosomes are the 
structure that carries long 
pieces of DNA. There are 23 
pairs of chromosomes 
present in humans from 
which 1 pair is of sex 
chromosomes that 
determine the sex of the 
child.
WHAT IS A DNA TEST?
DNA tests use a sample of a person to determine their DNA 
and then compare that with the reference database or some 
other relative to determine the biological relative or find the 
information of their ancestor.
WHAT IS AN AUTOSOMAL DNA 
TEST?
In this test, all the chromosomal pairs except the 
sex chromosome are checked to determine the genetic 
makeup of a person.
