Happy Hump-day Bellwork: Pull out any Vocabulary materials you need to study and do so...now!

Slide 2

DNA

Slide 3

TEST REVIEW RULES Pull out a few sheets of paper or a notebook You will be grouped by tables for this activity Your table will rotate to a new table every three minutes. (table one moves to table two, table two moves to table three, table seven moves to table one and so on) While at your station your challenge will be to write down and try to answer as many of the questions as possible with your group before time is up. If you dont know the answer use your notes or HEYflip the page over

Slide 4

Where does the process of Translation occur in the cell?

Slide 5

Answer: The process of translation occurs in the ribosome of the cell.

Slide 6

Name the process in which mRNA is made and where it occurs.

Slide 7

Answer: Transcription Occurs in the nucleus of the cell.

Slide 8

What are the four nitrogenous bases found in RNA?

Slide 9

Answer: Adenine, Uracil, Cytosine, Guanine

Slide 10

Would you see the following sequence in DNA or RNA? Why? ACC GGC CAC GCG AAC AGA UAG GGC CAG

Slide 11

Answer: RNA The sequence contains uracil at the 7 th codon

Slide 12

What is the sugar found in the RNA nucleotide?

Slide 13

Answer: Ribose

Slide 14

Which nitrogenous bases pair together in RNA?

Slide 15

Answer: Adenine Uracil Thymine Adenine Cytosine Guanine

Slide 16

Examine the two mRNA sequences. Has a mutation occured? How do you know? AUG CGA GGG CUA AAA CAG UAC AUG CGA GGG CCA AAA CAG UAC

Slide 17

Answer: Yes a point mutation (substitution of a base) has occurred at the fourth codon.

Slide 18

What is a codon and what does it do?

Slide 19

Answer: A 3 nucleotide sequence of mRNA that tells tRNA what amino acid to bring to the ribosome

Slide 20

GET YOUR CODE ON!! What amino acids will be obtained from the following codons: AUG CAG UUU GGC

Slide 21

Answer: AUG will give you methionine CAG will give you glutamine UUU will give you phenylalanine GGC will give you glycine

Slide 22

What is a polypeptide?

Slide 23

Answer: The polymer of a protein. It is composed of many amino acids linked together.

Slide 24

What is a mutation?

Slide 25

Answer: A mutation is a change in genetic material that results from a mistake in the replication process Can also be caused by environmental factors

Slide 26

What are the monomers for a carbohydrate, lipid, and protein. Which one contains Nitrogen?

Slide 27

Answer: The monomer of a______ is a _________ Carbohydrate Monosaccharide Lipid Fatty Acid Protein Amino Acid Only the Protein contains Nitrogen (N).

Slide 28

Where are proteins produced in the cell?

Slide 29

Answer: In the ribosome

Slide 30

How many different substrates can fit with one enzyme?

Slide 31

Answer: Only one. They are very specific.

Slide 32

What is a cell membrane mainly composed of? (its a bio-molecule)

Slide 33

Answer: The cell membrane is mostly composed (made up of) LIPIDS

Slide 34

How is a prokaryotic cell different from a eukaryotic cell?

Slide 35

Answer: Prokaryotic cells do not contain a nucleus or membrane bound organelles. They carry their DNA in the cytoplasm while Eukaryotic cells carry their DNA in the nucleus.

Slide 36

Give one example of a prokaryotic organism.

Slide 37

Answer: Bacteria

Slide 38

Give one example of a eukaryotic organism.

Slide 39

Answer: Plants, Animals, Fungi..basically any living thing is a Eukaryotic organism except for Bacteria.
