1-7-13 Midterm Reflection/Review

Today’s Plan

• Review class rules and go over important class information

• Midterm Exam Reflection• Review key concepts from first semester

Class Rules• Please summarize the class rules in your own

words. Write your summary of the rules in your lab book.

Class Rules Continued

• Are the rules clear? • Do the rules apply to everyone?

Consequences

• Write the list of consequences, in order, in your lab book.

Consequences Continued • Is it a big deal to get a “warning” in this class?• Is it a big deal to move seats and do a think

sheet?• Is it a big deal for the teacher to call home

and/or give a referral?• Is it reasonable for the teacher to skip a

consequence for certain behaviors?• Is it reasonable for the teacher to skip a

consequence for continual repeated misbehavior?

Important Info• Lab books: – If your lab book is running out of pages or is

messy, you can and should get a new one, soon.– Lab books are graded on having all pages

numbered, having an updated Table of Contents, having an updated Glossary, and having all work complete.

Important Info Continued• Late work:– Late work will no longer be accepted all semester

long.– Instead, you have 2 weeks after the assignment

was due to hand it in and still get credit (up to 75%).

Important Info Continued• Missing work:– If you miss class it is your responsibility to

get what you missed as soon as possible.• Get missing work before school, after school,

and sometimes during advisory.

Important Info Continued

• Do Nows:– You are expected to write the questions for every

Do Now.– You are expected to have an answer for every Do

Now, even if it is just a guess.– When we go over the answers, you are expected

to write the correct answer, even if that means changing or adding to your answer.

• Any other questions about class expectations?

Midterm Exam Class Averages

• 1st hour: 74.0%• 2nd hour: 73.5%• 3rd hour: 77.6%• 4th hour: 75.7%• 6th hour: 69.5%• 7th hour: 60.0%

Midterm Exam Reflection• Complete your reflection sheet, your test

tracker sheet, and place the midterm in the metal prongs of your folder.

• When you are done, place a green sticker on your best topic and a purple sticker on your worst topic. Only choose one best topic and one worst topic.

• Then put away your folder neatly.

Review Midterm Content

A circle will be shown. Your job is to identify the word or idea that does not belong in the circle. Then you will have to provide a short explanation why it does not belong.


Example:

Hypothesis Constant

Variable Genotype


• Number your lab book to 6 and skip one line between each number.

• Remember: For each circle, you have to identify the word that doesn’t fit and tell why it doesn’t fit.

Chromosomes and Inheritance

Today’s Plan

• Read about genes in the “What Is a Gene” reading

• Take notes on chromosomes and inheritance• Complete the Chromosome Worksheet• Exit Slip on chromosomes

Why are we learning this?

• Learning about chromosomes and DNA helps us identify relatives and criminals. It helps us learn about people and organisms from long ago. It helps us treat and cure diseases. It helps us understand why we are the way we are.

“What Is a Gene” ReadingAnswer the following questions in complete sentences your lab book:1. Describe a time when you experienced something

like Nancy did with her family at the beginning of the article.

2. Write the definitions for each of these words: genes, traits, chromosomes, nucleus, and genetic engineering.

3. Where are genes located?4. Where do the chromosomes in the nucleus come

from?5. What can happen if genes are changed in some way?

Notes on Chromosomes and Inheritance

Remember to write everything written in red and everything your teacher asks you to.

• What are some things that Gregor Mendel did to prove that genes existed?

• Gregor Mendel showed that genes exist, but scientists still had to learn where those genes are located in plants and animals.

• Where do you think we find genes?– Write your prediction in your lab book.

• Genes are located in cells.• The nucleus of a cell contains chromosomes,

and that’s where the genes are located.

• A chromosome is the threadlike structure in a cell that carries hereditary information (DNA).

Draw a picture of a chromosome

• Walter Sutton helped develop a theory that applied some of Mendel’s ideas.

• Sutton thought chromosomes were important to the inheritance of traits.

• What was Mendel obsessed with?

• Pea Plants!!

• What do you think Sutton was obsessed with?

• Grasshoppers!!

• Sutton studied grasshopper cells and found:– All cells in their bodies had 24 chromosomes.– Sex cells (sperm and egg) each had 12

chromosomes.

Why were there 24 chromosomes in the grasshopper’s body? Explain your answer in a sentence in your lab book.

• Sutton found that when sperm and egg join there are 24 chromosomes.– One set of chromosomes (12) came from the

father.– One set of chromosomes (12) came from the

mother.12 + 12 = 24

• Fruit flies have 4 chromosomes. How many came from each parent?

• A pig has 40 chromosomes. How many came from each parent?

• Humans have 46 chromosomes. How many came from each parent?

• Half of your chromosomes come from your dad and half come from your mom.

• What are alleles again?– Different forms of a gene.

• Paired alleles are carried on chromosomes.– One allele in a pair comes from the mother.– One allele in a pair comes from the father.

• The theory Sutton helped develop is called Chromosome Theory.

• This theory states that genes are carried from parents to offspring on chromosomes.

• What is carried on chromosomes?

• How many sets of chromosomes do grasshoppers receive?

• Where does each set of chromosomes come from?

• If an organism has 30 chromosomes, how many chromosomes came from the mother and how many came from the father?

• Do you think that an organism can have an odd number of chromosomes?

Glossary

• Add these words and their PAGE NUMBERS to your glossary.– Chromosome– Chromosome Theory

Complete the Chromosome Worksheet by yourself or with your tablemates

Exit Slip• Make your notecard look like the one below.

Labeling your note card correctly is worth one point.

DNA

Today’s Plan

• Take notes on DNA• Complete a DNA brace map• Complete Genetics Challenge worksheet• Exit Slip

• Homework today: DNA Homework

Review Key Concepts

• Traits are passed from parent to offspring• Traits are passed on through genes• Genes are specific sections of DNA• In sexual reproduction, offspring get half of

their genes from each parent from chromosomes

DNA notes

• Remember to write everything in red and everything your teacher asks you to.

•DNA = deoxyribonucleic acid

• DNA is a molecule that stores information. • DNA holds the instructions for making

proteins.• It is like a cookbook that contains the

instructions for making a cake, except DNA contains the instructions for making an organism.

Explain the images in your own words. Relate it to DNA.

A DNA molecule is shaped like a twisted ladder.

Draw an example of DNA.

• DNA is formed by subunits (smaller parts) that include:– Phosphate– Sugar (Deoxyribose)– Nitrogen base

What’s DNA made out of?

What 3 things make up DNA?

• The side rails of the ladder are formed by the sugar and the phosphates.

The purple in the pictures are where the phosphate and sugar are located.

Where are the sugar and phosphate located?

• The rungs of the ladder (the bars that go across) are formed by two bases coming together.

Where are the bases located?

What do you notice about how the bases are paired together?

• There are 4 different bases in DNA:– Adenine (A)– Thymine (T)– Cytosine (C)– Guanine (G)

What are the 4 bases in DNA?

• A and T always pair• C and G always pair

• It’s like A and T are BFFs and C and G are BFFs.

How do the bases pair together?

• The sequence (order) of bases in a strand of DNA makes the code for building proteins.

• The Genetic Code is a “triplet” code, meaning that every 3 bases codes for 1 amino acid.

• A gene is the entire sequence of bases that codes for a specific protein.– The genetic code is like a recipe for a

specific dish.

Create a similar

diagram.

Glossary

• Add these words and their PAGE NUMBERS to your glossary.

• DNA• Genetic Code

Which doesn’t belong and why?

Nitrogen base

Sugar

Phosphate Protein

Which doesn’t belong and why?

Adenine Thymine

Phosphate Guanine

DNA Brace Map• To make your brace map, think about what

DNA is made out of. Your brace map should look similar to the one below, although you can have a different number of lines and the lines can be in different places.

Complete the Genetics Challenge

Please complete this part by yourself.

You can use your lab book.

Exit Slip• Make your notecard look like the one below.
