TEAS 7 Biology: 20 Must-Know Questions for Exam
Success
Interphase (Mitosis)
cell growth and DNA replication (loose and messy like worms)
Prophase (mitosis)
nuclear envelope begins to dissolve, Chromatin condense into a "x" shaped chromosomes (X's)
Metaphase (mitosis)
chromosomes line up on metaphase plate
Anaphase (Mitosis)
cell elongates and sister chromatids are pulled apart toward the poles
Telophase (mitosis)
a cleavage furrow pinches the two daughter cells apart (cytokinesis). Each daughter cells left with 46
chromosomes
Which of the following describe a codon? (circle all that apply)
A. Codon is a sequence of three nucleotides that code for a specific amino acid.
B. A STOP codon signals to STOP protein synthesis
C. A START codon initiates protein synthesis and the nucleotide sequence for a start codon is AUG
D. A codon is a protein that codes for a gene.
Answers: A,B,C
Which of the following describes the independent variable in the experiment? (Use the following
information given)
A group of people in an experiment test out the effects of a new drug, "X". Group 1 is given a placebo
and reports having no side effects. (they are given none of the medication "X".)
Group 2 is given a full dose of the medication and reports having headaches.
Group 3 is given half the full dose of medication and reports having trouble sleeping.
A. Trouble sleeping is the independent variable.
B. "Trouble sleeping" and "headaches" is the independent variable
C. The amount of medication given is the independent variable; "placebo" "full dose" and "half dose" of
, medication are the independent variables.
D. The placebo medication is the only independent variable in the experiment
Answer: C
Dependent variable: The outcome of the independent variable( Example: if half dose is independent
then dependent would be trouble sleeping
What illustaration represents the correct nucleotide base pairing in DNA?
A: Adenine, Uracil, Guanine, Thymine
B: Adenine, Thymine, Guanine, Cytosine
Answer: B (there is no thymine in RNA)
(adenine pairs with thymine, guanine pairs with cytosine in DNA....adenine pairs with uracil, guanine
pairs with cytosine in RNA)
A phenotype is a characteristic trait that is observable. Phenotype is the expression of a genotype.
TRUE OR FALSE
TRUE
genotype is the letters
phenotype is what those letters represent
Match the correct macromolecules with the monomer they are made of
A. Carbohydrates
B. Lipids
C. Proteins
D. Nucleic Acids
Nucleotides, Amino Acids, Fatty Acids + Glycerol, Monosaccharides
A. Carbohydrates -> Monosaccharides
B. Lipids -> Fatty Acids+Glycerol
C. Proteins -> Amino Acids
D. Nucleic Acids -> Nucleotides
which part of the phospholipid bilayer is hydrophilic? Glycerol or fatty acids
Answer: Glycerol is hydrophilic, fatty acid is hydrophobic
Which of the following statements is true?
A. Humans have a total of 46 chromosomes. All chromosomes are either inherited from the mother or
from the father.
B. Humans have 2 different copies of one gene. One from the mother and one from the father. Each
variation of a gene is referred to as an ellele. Therefore, offspring will have 2 alleles for each gene.
