Review Questions for Chapter 18
2. A gene or a trait is said to be polymorphic if:
A) the allele frequency is about 50:50 for each of its alleles present in the population.
B) the allele frequency of one allele is higher than that of all others.
C) more t
Chapter 6 Review Questions
1. The gene C codes for the membrane-associated protein C, responsible for signal
transduction. A mutant allele of this gene, Cm, encodes a malfunctioning C protein, which has the
same size as the wild type, associates with the
Chapter 9 Review Problems
1. Formation of the peptide bond could be described as:
A) a spontaneous reaction between two peptides, forming a covalent bond.
B) a ribosome-catalyzed process occurring in the nucleus.
C) a tRNA catalyzed process.
D) a ribosome
4.1 Simple Inheritance Patterns
Simple mendelian: inheritance of alleles obey Mendels laws and follow a strict dominant/recessive
Incomplete dominance: heterozygote has a phenotype that is intermediate between either
3.1 General Features of Chromosomes
Chromosomes are structures within living cells that contain genetic material, complex between DNA
and proteins are called chromatin
Prokaryotes usually have a single type of circular chromosome in a region o

4. A strain of E. coli has the genotype (and phenotype) leu- lac-. This notation means that
this strain if bacteria is unable to:

Chapter 7 Questions
1. Suppose that protein had been found to be the hereditary material instead of DNA.
How would the results of the Hershey-Chase experiment with T2 infection of E coli
(a) Most of the radioactive sulfur (35S) would have b
Chapter 7 (and 19) Linkage and Mapping Part III
This chapter will study the genetics of bacteria
Bacteria produce asexually so genetic crosses are not used in analysis; rather, researchers rely on a
method known as genetic transfer in which a segment of b
