What is the role of DNA in living things?
Storing and copying information
Which scientist identified the shape of DNA as a helix using X Rays?
Rosalind Franklin
What conclusion can be drawn about the process of DNA replication?
It occurs during cell division
What is the significance of Chargaff's Rule?
It explains the base pair rule for DNA
What is the definition of Replication?
the process of copying DNA to produce an identical replica.
How does DNA differ from RNA in terms of structure?
DNA forms a double helix, while RNA is a single strand.
How does DNA replication ensure the accuracy of genetic information?
DNA polymerase proofreads and corrects errors in DNA sequences.
How does the structure of DNA contribute to its role in storing and copying information?
The double helix structure allows for easy replication and storage of genetic information.
How does the base pair rule contribute to the stability and integrity of DNA?
It ensures that each DNA strand has a complementary sequence, allowing for accurate replication.
How does the structure of DNA contribute to the process of gene expression?
The double helix structure allows for the precise pairing of nucleotides during transcription and translation.
What causes cells to become cancer cells?
Cells become cancer cells due to mutations in genes.
During which phase of mitosis do chromosomes line up along the equator?
Metaphase
What is the purpose of interphase in the cell cycle?
Interphase is the phase where DNA replication occurs.
What is the diploid number of chromosomes in humans?
46
Why is it important to understand the causes of cancer?
To find ways to treat cancer.
What is the purpose of cytokinesis in the cell cycle?
To divide the cytoplasm.
What is the purpose of interphase in the cell cycle?
Interphase is the phase where DNA replication occurs.
What is the purpose of the centromere in mitosis?
The centromere holds together identical sister chromatids.
How do mutations in genes contribute to the development of cancer?
Mutations in genes can lead to the development of cancer cells.
What is the significance of the diploid number of chromosomes in humans?
The diploid number determines the total number of chromosomes in every cell.
What is the main purpose of chemotherapy in treating cancer?
To stop the replication of DNA or stop spindle fiber formation
What is the purpose of the HPV vaccine mentioned in the text?
To reduce the risk of cervical cancer
What is the source of HeLa cells mentioned in the text?
Cervical cancer cells taken from a patient named Henrietta Lacks
What can be concluded about the effect of chemotherapy on healthy cells?
Chemotherapy damages healthy cells.
What conclusion can be drawn about the process of DNA replication?
It occurs during cell division
