DNA, Chromosomes, & Genes

Humans have

• 18 chromosomes in the the nucleus of each cell

• 23 chromosomes in the nucleus of each cell

• 46 chromosomes in the nucleus of each cell

• 46 pairs of chromosomes in the nucleus of each cell

What are chromosomes made of?

• DNA

• Cells

• Fats

• Carbohydrates

The genetic material that you are born with

• constantly changes

• changes if you get sick

• is identical to your parents

• is all the genetic material you will ever have.

Human egg or sperm cells have

• 46 chromosomes

• 18 chromosomes

• 23 chromosomes

• 1 chromosome from each parent

Each species has

• the same number of chromosomes in the nucleus of their cells. (All species have the same number of chromosomes.)

• a different number of chromosomes in their nucleus depending on the species.

• different number of chromosomes in their nucleus depending on the generation they are in.

• the same number of chromosomes as humans

DNA is found in

• the nucleus

• the golgi body

• the ribosome

• the cell wall

Hereditary material is

• carried from parent to child through the blood stream

• transferred from the digestive system

• carried from the nervous system

• transferred in the DNA through the egg and sperm of the parents

What is inheritance?

• the passing of traits from one generation to another

• the passing of injuries from one generation to another

• when you look like a relative

• when you get money from a relative

What is a protein?

• DNA

• a group of carbohydrates doing a job

• things that make up most of the cell membrane

• a chain of amino acids that performs a function for the body

What is a trait?

• the dense circular organelle in the cell

• characteristics of the organism

• the outside of a plant cell

• the green organelle in the cell
