Photosynthesis
What are the reactants for photosynthesis?
Carbon Dioxide, Water and Sunlight.
Explain interphase.
G1, G2, S ect.
What are three types of RNA.
What is heredity?
Heredity is the transmission of characteristics from the parents to the offspring.
What is heterozygous?
Heterozygous is containing two different alleles. Dominant trait is usually shown.
What are the products for photosynthesis?
Oxygen and Glucose
How many cells are created in Mitosis.
Two identical diploid daughter cells
What are the 5 nucleotides? Purines, Pyrimidines
Purines- Adenine Guanine
Prymidine- Cytosine, Thymine(DNA only), Uracil(RNA only)
Explain phenotype and genotype.
Phenotype-physical appearance
Genotype- alleles possessed.
What is homozygous?
Homozygous is when an individual contains two of the same alleles. Can be recessive or dominant.
Where does the Calvin Cycle ( light independent) reaction occur?
It occurs in the chloroplast.
How many cells are created in Meiosis.
4 haploid non identical cells.
Discuss DNA replication.
Helicase unzips DNA. DNA polymerase adds nucleotides. Ligase fixes.
Show on the board.
What is an allele?
An allele is one of two or more alternative forms of a gene that display a trait such as eye color.
Where does the light (light dependent) reaction occur?
It occurs in the thylakoid.
What are the steps of mitosis? Explain
PMAT
Transcription
Using one strand of DNA as a template to make RNA.
Dihybrid Tall homozygous with green seeds (recessive) crossed with heterozygous tall and heterozygous yellow parent.
Show on the board
Incomplete dominance is what?
Neither alleles is shown as dominant. Red x White=Pink
Explain chlorophyl
A pigment that helps absorb light in the chloroplast during the light dependent reaction.
Explain tetrad division.
•Each pair of homologous chromosomes line up to form four sister chromatids called a tetrad.
•Portions on the chromosomes break off and attach to the other chromatids. This is called crossing-over.
Translation
Using mRNA and tRNA to make proteins. mRNA codon, tRNA anticodon.
He crossed peas and discovered traits are inherited.
Dominant vs. Recessive
Dominant trait are shown with heterozygous dominant recessive alleles. Recessive is only shown with two homozygous alleles.
