◍ what represents the correct order of assembly in the cell.
Answer: Amino acid, polypeptide, protein
◍ t/f: A single base pair change in a gene's DNA sequence can affect the shape
and function of the protein it encodes..
Answer: true
◍ t/f:The three-dimensional structure of a protein is largely determined by the
amino acid sequence..
Answer: true
◍ A structural gene's code is 5' TAC ATG CCC TTA ATC 3', what will the
mRNA transcript be?.
Answer: 3' AUG UAC GGG AAU UAG 5'
◍ Circular, long DNA containing several thousand genes.
Answer: Prokaryotic DNA
◍ Cytoplasmic, circular DNA containing only a few genes.
Answer: plasmid DNA
◍ Linear, long pieces of DNA with many thousands of genes, contained within
a nucleus.
Answer: Eukaryotic DNA
◍ The enzyme maltase catalyzes the break down of maltose into glucose. A
technician added maltase to a solution of maltose to be incubated at 37°
C. Samples were taken from the reaction tube every five minutes over the
course of one hour, to measure the glucose concentration. After an hour, the
, technician noticed the water bath failed to reach 37°C (it only warmed to
25°C).Which of the following is the most likely outcome of the reaction?.
Answer: The enzyme activity would decrease, yielding the same level of
glucose over a longer time period.
◍ Carbon dioxide as a by-product benefits the brewing and baking industry in
a process called fermentation. When microorganisms (usually yeast)
undergo fermentation, they obtain their energy by:.
Answer: Anaerobic respiration
◍ t/f:A solvent is the dissolved matter in a solution..
Answer: false
◍ Carbohydrates.
Answer: Example: cellulose. Functions: energy storage, receptors, structure
of plant cell wall.
◍ Lipids.
Answer: Example: cholesterol. Functions: membrane structure, energy
storage.
◍ Nucleic acids.
Answer: example: RNA. Functions: information storage and transfers
◍ Proteins.
Answer: example: enzyme. Function: structure, receptors and transport
◍ bond type?: NaCl.
Answer: Ionic
◍ bond type?: H2O.
Answer: polar covalent
◍ bond type?:CH4.
Answer: nonpolar covalent
◍ Why is
E. coli usually incubated at 37°C?.
Answer: max growth rate
