STRUCTURE AND FUNCTION OF DNA


UNIT OUTCOMES:

(Chapter 10 DNA)


A)

Describe
the role

of DNA

in all cells and why it is so important that an
exact copy of the DNA is passed

on

to

every new cell when cell reproduction occurs in an organism.








(Pages 193 & 200)

B)

Describe
the structure

of DNA
. Name all molecules that are main components of the DNA molecule and draw

a simple diagram to represent the DNA molecules structure

and overall shape.




(Pages 196
-
199)

C)

Describe
how the DNA molecule is replicated

such that two identical copies result. Use a diagram to help

your explanation.

D
)

Using a diagram, explain the process of "
transcription
" as it occurs in the nucleus. Describe the purpose for
this process.

STRUCTURE AND FUNCTION OF DNA SELF STUDY GUIDE

1)

From chapter 10 pages 196
-
199 titled "Structure of DNA" be able to;





A)

Explain the two basic
functions of DNA.



B)

Explain the two main roles that proteins play in living organisms.



C)

Name the monomer that makes up the polymers known as DNA and RNA.



D)

Describe the three molecules that make up a nucleotide.



E)

Name the two molecules that m
ake up the side of the DNA molecule.



F)

Name the four types of bases found in DNA.



G)

Give the name that describes the twisted ladder shape of the DNA molecule.



H)

Name the two men who discovered the shape or structure of DNA.



I)

Name the woman wh
o first took pictures using X
-
Rays of the DNA molecule.



J)

Name the type of bond that connects the bases together in the center of the DNA.



K)

Explain why adenine always bonds to thymine and guanine to cytosine.



L)

Explain where the "code" or message

lies in the DNA molecule for the proteins.


2)

From chapter 10 pages 200
-
202 titled "DNA Replication" be able to;



A)

Give the term that describes DNA making a duplicate of itself.



B)

Describe how the DNA molecule replicates itself.



C)

Describe the r
ole of DNA helicase and DNA polymerase, the two enzymes involved in this process.



D)

Explain why the correct bases always find their way into position so that the two new








molecules are exactly like the original molecule of DNA.



E)

Explain where

the extra DNA nucleotides come from that make the new molecules.



F)

Explain whether the new molecules are composed of 2 new strands, 2 old strands, or one old and one





new strand. Why?



G)

Explain if replication occurs from one end to another or d
oes it occur in many places









simultaneously.


3)

From the chapter 10 pages 204
