2. What are genes?
Genes are small units of information
inside our cells that contain
instructions for how our bodies
develop and function.
They 'code' for traits like our eye
color, hair color, and height.
3. What is DNA?
DNA is a molecule that carries genetic
information in living organisms. It looks like
a twisted ladder (double helix) and is found
inside the nucleus of our cells.
DNA stands for deoxyribonucleic acid.
4. G
What is this genetic code
business?
The genetic code is like a language that
DNA uses to give instructions to cells.
It consists of combinations of four chemical units called nucleotides:
adenine (A), thymine (T), cytosine (C), and guanine (G).
C
6. What does the code
translate to?
Each gene's code uses A, C, G and T in various
combinations to code for a specific amino acid. is
needed at each position within a protein.
Amino acids are the building blocks for proteins. This
means our DNA codes for different proteins that
perform specific functions in our body.
7. Chromosomes are long, thread-like structures
made up of DNA and proteins. They carry many
genes and are found inside the nucleus of our cells.
Genes are segments of DNA located on
structures called chromosomes.
Where do our genes
hang out?
8. FUN FACT
Humans typically have 46
chromosomes, which come
in pairs, with 23 inherited
from each parent.
9. We need genes because they contain
the instructions for building and
maintaining our bodies.
Why do we need genes?
They also crucial role in passing
traits from parents to children
through reproduction.
10. FUN FACT
The Human Genome Project
has determined that
humans have an estimated
30,000 genes.
