Photosynthesis/Cellular Respiration
What is the overall goal of photosynthesis?
To make food/glucose for the plant
Where does transcription take place?
Nucleus
What shape is DNA?
Double Helix
How many checkpoints are in the cell cycle?
3
What cells are created through meiosis?
Gametes
What is the overall goal of cellular respiration?
To make energy/ATP for the organism
Where does translation take place?
Ribosome
What are the 4 base pairs in DNA? In RNA?
Adenine, Thymine, Cytosine, Guanine
Adenine, Uracil, Cytosine, Guanine
What is the main reason for cells to go through mitosis?
For growth, repair, and replace
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 reactants for photosynthesis?
Carbon Dioxide
Water
Which type of RNA carries the amino acids to the ribosome?
tRNA
What are the 3 types of RNA?
mRNA, tRNA, rRNA
Draw the cell cycle.
Interphase (G1 ,S, G2), M phase, Cytokinesis
Explain/Define crossing over.
Homologous chromosomes exchange pieces of DNA when overlapping chromosomal legs.
What are the products of cellular respiration?
ATP
Carbon Dioxide
Water
Translate the following mRNA codons AUG CCC GUA CAA UGA
Met - Pro - Val - Gln - Stop
DNA Replication is responsible for....
Making two exact copies of DNA; doubling chromosomes (92)
What happens when the checkpoints are ignored?
The cell continuously divides, leading to cancer
What is the main purpose for meiosis?
Variation in genetics and enhancing the species.
How are photosynthesis and cellular respiration connected to each other?
Both need each other to function. The processes are nearly opposite to each other. The reactants for one are the products from the other and vice versa.
Here is an original strand of DNA:
AAA TTC CGC ACT
Would anything change if the DNA was mutated to
AAA TTG CGC ACT
If yes, then identify the type of mutation AND identify the new amino acid.
Yes.
Substitution mutation.
LYS changed to ASN.
Draw Transcription.
Label the enzyme(s).
Transcription:
1 DNA strand is opened by RNA Polymerase and creates an mRNA strand that exits while the DNA strand is closed at the other end.
Draw DNA Replication.
Label the enzyme(s).
DNA Replication:
1 DNA strand is split by helicase into two strands that are being connected to new strands by DNA Polymerase.
