Quiz on Pathologic Basis of Disease

What does the term "Pathology" translate to in Greek, and what does it study?

• Pathos = feeling, logos = study; it studies the feelings of disease

• Pathos = suffering, logos = study; it studies the structure and function of cells under normal circumstances

• Pathos = suffering, logos = study; it studies the structure and function of cells under abnormal circumstances

• Pathos = disease, logos = reason; it studies the reasoning behind diseases

When was the sequencing of the human genome first published, and what was its significance?

• 2001, it was a landmark achievement in computer science

• 2003, it was a landmark achievement in biomedical science

• 2000, it marked the beginning of gene therapy

• 2005, it revolutionized the pharmaceutical industry

Approximately how many DNA base pairs does the human genome contain?

• About 1.5 billion DNA base pairs

• About 2.1 billion DNA base pairs

• About 3.2 billion DNA base pairs

• About 4.0 billion DNA base pairs

How many protein-encoding genes are there in the human genome according to the text?

• About 20,000

• About 15,000

• About 25,000

• About 30,000

What is the primary function of the noncoding DNA mentioned in the text?

Which of the following is a major class of functional non-protein-coding sequences found in the human genome?

• Transcription factors

• Promoter and enhancer regions

• Ribosomal RNA genes

• Transfer RNA genes

What is the role of heterochromatin in the cell?

• It is actively involved in the regulation of gene expression.

• It is a less condensed form of chromatin that allows transcription.

• It is a densely packed, transcriptionally inactive form of chromatin.

• It is the primary location for ribosomal RNA synthesis.

What percentage of the human genome does not encode proteins, according to the image?

• Less than 40%

• About 60%

• Over 95%

• Exactly 85%

Which of the following is NOT listed as a major class of functional non-protein-coding sequences in the human genome?

• Promoter and enhancer regions

• Binding sites for transcription factors

• Mobile genetic elements

• Special structural regions of DNA

What is the significance of non-protein-coding regions in the genome, as suggested by the image?

• They are less important than protein-coding regions.

• They are more important in disease causation than structural changes in specific proteins.

• They are only involved in the structural organization of the chromosome.

• They are exclusively composed of introns and untranslated regions.
