Chromosomes

What is the purpose of DNA replication?

• To repair damaged DNA
• To produce proteins
• To ensure proper segregation of genetic material
• To create more chromosomes

What is the term for the two identical copies of a chromosome that are attached to each other?

• Alleles
• Centromeres
• Sister chromatids
• Homologous chromosomes

What is the term for the process in which DNA condenses and coils into the familiar X-shaped form of a chromosome?

• Transcription
• Chromatin formation
• Replication
• Mitosis

What is the term for alternate forms of a gene?

• Centromeres
• Sister chromatids
• Alleles
• Homologous chromosomes

What is the structure of chromosomes?

• Grainy material called chromatin
• Coiled structures made of DNA and proteins
• Circular strands of DNA
• Linear strands of DNA

What is the purpose of DNA replication before cell division?

• To increase the size of the cell
• To create new genes
• To create more chromosomes
• To ensure each daughter cell receives a complete set of genetic material

Why is proper chromosome segregation important during cell division?

• To create more chromosomes
• To create new genes
• To ensure each daughter cell receives a complete set of genetic material
• To increase the size of the cell

What is the term for the material that DNA exists as during other phases of the cell cycle?

• Centromeres
• Chromosomes
• Genes
• Chromatin

What is the relationship between chromosomes and the nucleus?

• The nucleus is only found in prokaryotic cells
• Chromosomes are only found in eukaryotic cells
• The nucleus contains chromosomes
• Chromosomes form the nucleus

What is the function of the centromere?

• To produce proteins
• To attach sister chromatids
• To replicate DNA
• To form the nucleus
