DNA Replication

Replication Process

• DNA Helicase breaks hydrogen

bonds

• DNA separates “unzips” at the

replication fork

• DNA polymerase adds new

bases; [A] = [T] & [G] = [C]

• Move in opposite directions

• Continues until replication

of both strands complete

• Telomeres added to the ends of

new DNA strands

p. 350-352

DNA Replication

Prokaryote DNA Replication

• Start from a single point &

proceeds in two directions until

copied

Eukaryote DNA Replication

• May begin at dozens or even

hundreds of places, proceeding

in both directions until copied

p. 352-353

Housekeeping

Tomorrow, 7 Dec., is study time for advisory.

Exam 5 scheduled for Friday, 16 Dec.

• Combined chapter 12 & 10.

Chpt 10 Introduction

Cell Growth & Division

Essential Question:

How does a cell produce a new cell?

Chpt 10 Objectives

You will be able to answer the following questions.

• What are the problems that growth causes for cells & what

are the solutions that are in place?

• What are asexual reproduction & sexual reproduction & how

do they compare?

• What is the role of mitosis & how do chromosomes move

during this process?

Chpt 10 Vocabulary

Complete the vocabulary worksheet.

• Worksheet will be taped into your notebook for future

reference.

Assignment

Read sections 10.1 & 10.2.

• Tomorrow we will be discussing the process of cell division.

Wednesday

Entry Task

What are the two main reasons why cells divide rather than

continuing to grow?

• Information overload - demands on the DNA

• Exchanging materials - moving nutrients & waste across the

cell membrane.

Exam 5 scheduled for Friday, 16 Dec.

• Combined chapter 12 & 10.

• Review (Kahoot) on Thursday 15 Dec.

Cell Division

The larger a cell becomes, the more demands the cell places on

its DNA. In addition, a larger cell is less efficient in moving

nutrients & waste materials across the cell membrane.

Limits to cell size:

• Information “Overload”

• Exchanging Materials

Division of the cell

Asexual vs. Sexual

Advantage

Asexual Sexual

Disadvantage

Entry Task

What are the two stages of the cell cycle?

• Interphase & Mitosis

What are the phases of each stage?

• Interphase = Gap 1 (G1), Synthesis (S), & Gap 2 (G2)

• Mitosis = Prophase, Metaphase, Anaphase, & Telophase

Planaria Regeneration Activity tomorrow, 9 Dec.

Exam 5 scheduled for Friday, 16 Dec.

• Combined chapter 12 & 10.

• Review (Kahoot) on Thursday 15 Dec.

Chromosomes

• Chromosomes make it possible to separate DNA precisely

during cell division.

(Sister Chromatids)

The Cell Cycle

Each group should have a dry erase board, dry erase marker, &

eraser.

Groups will draw & give a bulleted description of their phase.

A = Gap 1 (G1) E = Metaphase

B = Synthesis (S) F = Anaphase

C = Gap 2 (G2) G = Telophase

D = Prophase H = Cytokinesis

One individual from each group will describe the phase to the

class.

Cell Division Foldable

Complete the foldable according

to the directions:

• Construct your foldable.

• Label each of the section like

the model to the right.

• On each section will include a

drawing & written description.
