DNA/RNA
What shape is DNA?
Double Helix
What is the overall goal of photosynthesis?
To make food for the plant
Where does transcription take place?
Nucleus
How many checkpoints are in the cell cycle?
3
What cells are created through meiosis?
Gametes
What are the 4 base pairs in DNA? In RNA?
Adenine, Thymine, Cytosine, Guanine
Adenine, Uracil, Cytosine, Guanine
What is the overall goal of cellular respiration?
To make energy for the organism
Where does translation take place?
Ribosome
What is the main reason for cells to go through mitosis?
For growth and Repair
True or False, at the beginning of meiosis, you start off with a haploid cell and end with 4 haploid cells.
False. Start with a diploid cell and end with 4 haploid cells.
What are the 3 types of RNA?
mRNA, tRNA, rRNA
What are the inputs/reactants for photosynthesis?
Sunlight
Carbon Dioxide
Water
Which RNA is involved in translation?
tRNA and rRNA
What are the 3 stages of the cell cycle?
What does it mean when homologous chromosomes exchange pieces of DNA?
Crossing over
DNA Replication is responsible for....
Making two exact copies of DNA
What are the products/outputs of cellular respiration?
ATP
Carbon Dioxide
Water
Translate the following mRNA codons AUG CCC GUA CAA UGA
Met-Pro-Val-Gln-Stop
What happens when the checkpoints are ignored?
The cell continuously divides, leading to cancer
What does meiosis help provide to the population that mitosis does not?
Variation in genetics
What are the parts of a nucleotide?
Phosphate
Sugar
Nitrogenous Base
How are the two processes, photosynthesis and cellular respiration, connected to each other?
Both need each other to function. The reactants/inputs for one, are the products from the other and vice versa.
Here is an original strand of DNA: AAATTCCGCACT
Would anything change if the DNA was mutated to
AAATTGCGCACT? If so, what changed?
Yes. The protein LYS changed to Asn
When exactly does DNA replication occur?
In S phase during interphase
What is the main difference in divisions between cells in mitosis and cells in meiosis?
Mitosis- cells divide once
Meiosis- cells divide twice
