Flashcards in Exam 3 Review Deck (42):
Where does translation occur?
What does translation produce?
What type of RNA contains anticodons?
Which type of RNA acts as an enzyme?
Which type of RNA delivers amino acids to the ribosome?
Which type of RNA is part of a ribosome?
Which type of RNA is active in the cytoplasm?
rRNA, tRNA, and mRNA
Which type of RNA is clover-leaf shaped?
Which type of RNA has codons?
What type of bond is a peptide bond?
What two atoms link in a peptide bond?
C - N
What structure consists of two or more polypeptides working together?
What structure is 3D and stabilized by interactions among R-groups?
What structure is a sequence of amino acids?
What structure is an alpha helix or beta pleated sheet?
What does denature mean in reference to proteins?
change in protein shape due to environment
Define enzyme specificity.
the degree to which an enzyme is particular in its ability to catalyze a singular reaction, refers to enzyme shape
List some attributes of enzymes.
1. they catalyze chemical reactions
2. they control metabolism
3. they are sensitive to temperature and pH
4. they are reusable
In which type of enzyme regulation do the substrate and inhibitor both fit the active site?
In which type of enzyme regulation must the enzyme have 4^0 structure?
In which type of enzyme regulation does the product control the reaction?
What does meiosis produce in the human life-cycle?
mitosis or meiosis- ploidy level of product does not differ from ploidy level of parent cell
mitosis or meiosis- is always fallowed by cytokinesis
mitosis or meiosis- recombination may occur
mitosis or meiosis- chromosomes condense and become visible
mitosis or meiosis- DNA replicates prior to it
mitosis or meiosis- utilizes a spindle
mitosis or meiosis- produces four daughter cells
mitosis or meiosis- is responsible for growth and wound healing
When does the spindle re-orient perpendicular to the original spindle?
When does crossing over occur?
After which phase does interkinesis occur if any?
How many possible different types of gametes can an individual with the following genotype produce? AaBbCcDdEe
What is a device used to predict all possible gametes with a known genotype?
One allele can mask the expression of another allele.
Law of Dominance
If an organism is described as homozygous dominant, for example.
The expression of genes or how an organism looks.
A mechanism that predicts the genotypes of all possible outcomes from all possible gamete combinations.
If you get a phenotypic ratio of 9:3:3:1 in the F2 generation of sprees, what was the genotype of the grandparents (P generation)? What type of cross is this?
one homozygous dominant, one homozygous recessive
Red flower color is dominant to white flower color. When I crossed a homozygous red flower to a homozygous white flower, all of the offspring were pink. What's going on?
