GeneticsToday I will define and recognize genes, DNA, and chromosomes

Genetic Material

•Chromosomes, DNA, Genes, and Traits are genetic material found in the nucleus of the cell

5

Genes carry information that helps make you who you are

Genes are segments of Chromosomes

A gene is a section of DNA thatcontrols a trait ( ex. tall /short) that an

organism inherits

TPS: if genes are sections of DNA, where are genes located in the cell?

6

What do you know about DNA?

Where have you

heard the term?

What was the context

or situation?

DNA

Write this in your notebook and be ready to share with your class as your teacher records on the board.

DNA and Crime Solving• Because DNA is a nonliving, nonreactive chemical

molecule…• It can be recovered from mummies over 2000 years old.• DNA is found in dried blood in murder investigations• DNA can be found in ancient bones

8

What is DNA?• The genetic material

that carries information about an organism passed from parent to offspring

• DNA is a complete set of instructions necessary to make and maintain the human body.

• DNA is a blueprint of the human body

Compare Blueprint to recipe

Where is DNA?

Found in Cells…

DNA is wound tightly into

structures called Chromosomes so it can fit into a tiny

cell…

inside the Nucleus , the

Control Center.

so, Chromosomes are

made of DNA

Short sections of DNA are called

Genes

Chromosomes

• Chromosomes are DNA wrapped around proteins to form an X-shaped structure.

• Chromosomes are located in the nucleus of a cell

• A chromosome is formed from a single DNA molecule that contains many genes.

Each human Cell have 23 pairs of Chromosomes
