Happy Hump-day Bellwork: Pull out any Vocabulary materials you need to study and do so...now!
DNA
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 don’t know the answer use your notes or HEY…flip the page over
Where does the process of Translation occur in the cell?
Answer: The process of translation occurs in the ribosome of the cell.
Name the process in which mRNA is made and where it occurs.
Answer: Transcription Occurs in the nucleus of the cell.
What are the four nitrogenous bases found in RNA?
Answer: Adenine, Uracil, Cytosine, Guanine
Would you see the following sequence in DNA or RNA? Why? ACC GGC CAC GCG AAC AGA UAG GGC CAG
Answer: RNA The sequence contains uracil at the 7 th codon
What is the sugar found in the RNA nucleotide?
Answer: Ribose
Which nitrogenous bases pair together in RNA?
Answer: Adenine Uracil Thymine Adenine Cytosine Guanine
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
Answer: Yes a point mutation (substitution of a base) has occurred at the fourth codon.
What is a codon and what does it do?
Answer: A 3 nucleotide sequence of mRNA that “tells” tRNA what amino acid to bring to the ribosome
GET YOUR CODE ON!! What amino acids will be obtained from the following codons: AUG CAG UUU GGC
Answer: AUG will give you methionine CAG will give you glutamine UUU will give you phenylalanine GGC will give you glycine
What is a polypeptide?
Answer: The polymer of a protein. It is composed of many amino acids linked together.
What is a mutation?
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
What are the monomers for a carbohydrate, lipid, and protein. Which one contains Nitrogen?
Answer: The monomer of a______ is a _________ Carbohydrate Monosaccharide Lipid Fatty Acid Protein Amino Acid Only the Protein contains Nitrogen (N).
Where are proteins produced in the cell?
Answer: In the ribosome
How many different substrates can fit with one enzyme?
Answer: Only one. They are very specific.
What is a cell membrane mainly composed of? (it’s a bio-molecule)
Answer: The cell membrane is mostly composed (made up of) LIPIDS
How is a prokaryotic cell different from a eukaryotic cell?
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.
Give one example of a prokaryotic organism.
Answer: Bacteria
Give one example of a eukaryotic organism.
Answer: Plants, Animals, Fungi…..basically any living thing is a Eukaryotic organism except for Bacteria.
