131

Where is DNA located?

132


In the nucleus

133

134

Does the DNA ever leave the nucleus?

135

Does the DNA ever leave the nucleus?

No

136

What is the purpose of DNA?

137

What is the purpose of DNA?

It stores the complete genetic

information regarding the

organism

138

What is a more specific purpose of

DNA?

139

What is a more specific purpose of

DNA?It contains all the information needed to make proteins – the molecules that determines the

identity of the organism.

140

What are proteins made of?

141

What are proteins made of?

amino acids (20)

142

So are proteins made in the nucleus

where the DNA is located?

No

143

Well, where are they produced?

144

Well, where are they produced?

In the ribosomesRibosomes are located in the cytoplasm on the endoplasmic reticulum

146

Time out!

1. If the DNA contains the info for making proteins but does not leave the nucleus and:

2. The proteins are made at the ribosomes in the cytoplasm, then:

147

How does the cell get the genetic code for making proteins from the

nucleus to the ribosomes?

148



The genetic code is copied onto

RNA

149



The genetic code is copied onto

RNAAnd the RNA carries the coded information to the ribosomes

150

What does the DNA macromolecule look like?

151

What does the DNA macromolecule look like?
