B1 - You And Your Genes
- What is your Genome?
- Humans,other animals, and plants look a
lot like their parents.This is because they
have inherited genetic information from
them.This information controls how an
organism develops and functions.It is
stored in genetic material. All the genetic
material of an organism is called its
genome
- You can some features that are effected by the environment e.g. a scar. Almost all of
your features are affected by both the genetic information you inherited and the
environment.
- For example, your your height and body mass because you
keep growing and changing this is effected by the
environment and what you do ! You weren't born with just
one size body mass and you don't stay the same height. It
changes.

- Eukaryotic organism - it's a type of organism that has cells with a nucleus and
organelles with membranes. Includes all animals, plants, fungi and protists.
- Prokaryotic organism - it's a type of organism that is made up of cells that
do not have a nucleus or organelles with membranes.Such as bacteria.
- Some bacteria contain small loops of genetic
material. Each loop is caled a plasmid. Plasmids
can be used in genetic engineering.

- If you could see inside the nucleus, you would see the genetic material. It
is stored as long threads called chromosomes
- There are 46 chromosomes in a nucleus of a human body cell.Chromosome are in pairs;
in a human cell there are 23 pairs. Chromosomes are made up of very long molecules of
DNA

- What is DNA?
- The structure of DNA was discovered in 1935 by
James Watson and Francis Crick.
- The DNA consists of two strands that are twisted together to form a double helix.
- Each strand of DNA is a long molecule made from lots of small molecules
joined together in a chain. The small molecules are called nucleotides.
- Each strand of DNA is a long molecule made from lots of small molecules
joined together in a chain. The small molecules are called nucleotides.
- DNA is an example of a natural polymer. A polymer is a long chain molecule
made from lots of small molecules, called monomers, joined together.
Nucleotides are monomers that join together to make the DNA polymer.
- The structure of DNA was discovered in 1935 by
James Watson and Francis Crick.
- What are Genes?
- A gene is a region of DNA
- Each of your chromosomes contain many genes.
- Genes contain the instructions that cells use to make
proteins. Each cell nucleus contains the instructions
for making every protein in the human body
- A gene is a region of DNA
- What are proteins?
- Proteins are important Molecules
- There are many different proteins, which can be :
- structural - for example collagen (a
protein found in connective tissues)
- functional - for example amylase
(an enzyme that speeds up
chemical reactions)

protein found in connective tissues)
