Dna Chapter 1 Review Questions And Answers
REVIEW QUESTIONS CHAPTER 1
1. Place the following terms in size order, from largest to smallest, based on the structures or concepts they represent:
a. chromosome
b.gene pool
c. gene
d. DNA
e. genome Gene pool, genome, chromosome, gene, DNA
2. Distinguish between: a. an autosome and a sex chromosome b. genotype and phenotype c. DNA and RNA d. recessvie and dominant traits e. pedigrees and karyotypes f. gene and genome
a. An autosome does not carry genes that determine sex. A sex chromosome does. b. Genotype is the allele constitution in an individual for a particular gene. Phenotype is the physical expression of an allele combination. c. DNA is a double-stranded nucleic acid that includes …show more content…
8.Expain the protections under the Genetic Information Nondiscrimination Act, and the
Limitations
GINA protects people from being fired or denied health insurance based on genetic testing, for companies or organizations above a certain size. Limitations include extent and type of coverage (no life insurance) and specific sanctions for violations.
9.Explan what an application of a “diseasome” type of map (figure 1.8 might provide help)
A diseasome might show that drugs effective for one disease might be useful in treating another disease, to which it is linked by gene expression patterns.
10.Cite an example of phrase that illustrates genetic determinism
Answers vary depending on student experience. “He has the gene for sense of humor,” or “She has the gene for a great sense of style.”
11.Give an example of a genome that is in a human body, but is not human
The genome of a bacterial species that lives in the human
