What is double helix?
What kind of cells are produced as a result of mitosis?
What happens during transcription and where does it occur?
What is DNA is rewritten into mRNA in the nucleus?
What is a mutation?
What is A permanent change in the nucleotide sequence of DNA?
Enzymes are what type of biomolecule?
What is proteins?
What are the three main differences between DNA and RNA?
What is
Double stranded vs. single stranded
Deoxyribose vs. ribose
Thymine vs. uracil
When in the cell cycle is DNA replicated?
What is S phase?
What is translation and where does it occur?
What is mRNA is read/decoded by the ribosomes to produce proteins; occurs in the cytoplasm
The following is an example of which type of mutation?
Normal DNA: CGA – TGC – ATC
Mutated DNA: CGA – TAG – CAT - C
What is insertion mutation?
What are TWO main differences between eukaryotes and prokaryotes?
What is
Prokaryotes: NO nucleus & are bacteria only
Eukaryotes: nucleus & plants, animal, protist, and fungi cells.
Which substances make up the backbone of DNA?
What is sugar (deoxyribose) and phosphate?
During which phase of the cell cycle does the nuclear envelope break down, spindle fibers form, and chromosomes condense?
What is prophase?
Transcribe the following sequence:
TAG CCG GTA
What is AUC GGC CAU ?
The following is an example of which type of mutation?
Normal DNA: CGA – TGC – ATC
Mutated DNA: CGA – TCA- TC
What is deletion mutation?
In which process is ATP produced?
What is cellular respiration?
What kind of bond holds together the nitrogen bases of DNA?
What is hydrogen bonds?
List the correct order of the four phases of mitosis
What is Prophase, Metaphase, Anaphase, Telophase?
What molecule delivers amino acids to the ribosome?
What is tRNA?
If all body cells in a person have the same DNA, what allows them to be specialized?
What is not all DNA is expressed in each cell—different parts of DNA are used in each cell (protein synthesis)
What is the relationship between photosynthesis and cellular respiration?
What is the products of one become the reactants of the other.
If a cell contains 20% thymine, how much guanine will it contain?
What is 30 % guanine?
Draw and label the cell cycle with correct order of stages on the board-
What is
G1, S, G2, PMAT, Cytokinesis
DNA --(Process A)--> RNA --(Process B) --> Protein
Label processes A & B.
What are the significance of checkpoints in the cell cycle & how can they affect DNA?
What is DNA mutations. If checkpoints fail to catch mutations, it can lead to cancer.
Name and describe the functions of the four biomolecules?
What is
- Carbs- Quick energy source
- Lipids- Long term energy storage
- Proteins- enzymes, builds muscles, antibodies,
- Nucleic acids- store genetic info
