Exam 48: Genetics and Heredity

Match each term with its corresponding definition or description. -Analysis of proteins encoded by the genome

One form of gene therapy uses bacteria-like DNA plasmids to carry therapeutic genes to a cell.

Match each condition with its corresponding statement or definition. -Nervous disorder characterized by involuntary trembling and muscle rigidity

Every cell in the human body, both male and female, contains 46 chromosomes.

The syndrome that results from the genotype "XXY" is:

A strand of DNA wound around a histone is called a nucleosome.

Explain the structure of the chromosome. What is the difference between a chromosome and chromatin?

What is mitochondrial inheritance? Why does it only involve the mother and what type of diseases or deficiencies are caused by mitochondrial genes?

The manner in which the genotype is expressed is called the phenotype.

If an individual has only an X chromosome ("XO"), then that person is genetically:

Sickle cell inheritance is a good example of how codominance works.

Disease genes never provide biological advantages for human populations, regardless of the circumstances.

There are no normal alpha hemoglobin chains in a person with sickle cell anemia.

Because there have been tragic setbacks is some gene therapy clinical trials, there are presently no approved gene therapies available.

The term pedigree refers to the entire collection of genetic material in each typical cell of the human body.

Which of the following diseases is carried by mitochondrial DNA?

If "A" stands for the dominant gene that prevents albinism and "a" stands for the recessive albinism trait, then an individual with the genotype of "aa" will express:

Chromatin and chromosomes are both forms of DNA.

The sperm cytoplasm rather than the sperm nucleus is responsible for transmission of mitochondrial DNA.

Match each term with its corresponding definition or description. -Analysis of the genome code
