Unit 3 and 4 Test Review

Mutations

100

This is the complementary mRNA strand of this DNA strand a GGCATAGAAGCTA.

What is CCGUAUCUUCGAU?

200

This is the smallest unit of DNA. (Hint: It is the building block of DNA, also known as its monomer.)

What is Nucleotide?

300

This is the type of mutation is happening in this mutated strand of DNA.

Original: A-G-G-T-C-G-A-A-T         

     T-C-C-A-G-C-T-T-A

Mutated: A-G-C-G-T-C-G-A-A-T  

                    T-C-G-C-A-G-C-T-T-A        

What is insertion?

400

This is the amino acid sequence associated with this mRNA strand: A-U-G-A-A-A-U-C-A (Hint: Codon Chart)

What is Methionine-Lysine-Serine?

500

This is the type of point mutation is happening in this mutated strand of mRNA.

Original: A-G-G-U-C-G-A-A-U         

Mutated: A-G-G-U-C-U-A-A-U

(Hint: Need your codon chart)

What is silent mutation?

Translation and Transcription

100

This is the mRNA copy of this DNA strand: A-T-A-G-C-T-G-C-A

What is U-A-U-C-G-U-C-G-U

200

This is the bond that holds the two strands of DNA together. The bond must be broken to separate the two strands of DNA before transcription can take place.

What is hydrogen bond?

300

This is what is created after enzymes copy the DNA strand during transcription.

What is mRNA?

400

After transcription the mRNA leaves the nucleus in search of this organelle in charge of creating proteins.

What is a ribosome?

500

This biomolecule attaches the mRNA to read the codon. It brings with it an amino acid to add to the chain.

What is tRNA

Photosynthesis vs. Cellular Respiration

100

During photosynthesis plants convert this energy into a chemically stored form of energy known as glucose. 

What is light energy?

200

This is the organelle where cellular respiration takes place.

What is the mitochondria?

300

These are the 2 reactants of photosynthesis.

What is Carbon Dioxide and Water?

400

These are the 2 products of cellular respiration.

What is Carbon Dioxide and Water?

500

This is the equation for photosynthesis. (You can write it on paper or on the board)

What is 6CO2 + 6H2O → C6H12O6 + 6O2?

Mitosis

100

This is the phase of interphase where DNA is replicated.

What is S-Phase?

200

During this phase of mitosis DNA is condensed into chromosomes and the nucleus of the cell disintegrates. 

What is prophase?

300

This is what happens during the stage of mitosis known as metaphase.

What is chromosomes line up in the middle and spindle fibers connect to both sides of the chromosome?

400

This is the final stage of cell division where the cytoplasm splits and we get 2 identical daughter cells.

What is cytokinesis?

500

This is all of the stages of cell division in order.

What is interphase, prophase, metaphase, anaphase, telophase, and cytokinesis?
