How can DNA repair itself to maintain genetic integrity?
DNA repair mechanisms are essential for maintaining genetic integrity by fixing any damage or errors that occur in the DNA molecule. There are several pathways that cells use to repair DNA, such as base excision repair, nucleotide excision repair, and mismatch repair. These pathways involve specialized proteins that recognize and correct different types of damage, ensuring that the DNA remains stable and functional.
Is the DNA in prokaryotic cells circular or eukaryotic cells?
The DNA in prokaryotic cells is circular, while the DNA in eukaryotic cells is linear.
Is it true or false that prokaryotic cells contain more DNA than eukaryotic cells?
False. Eukaryotic cells generally contain more DNA than prokaryotic cells. Eukaryotic cells have their DNA enclosed within a nucleus, whereas prokaryotic cells have their DNA located in the cytoplasm.
Do prokaryotic cells have circular DNA?
Yes, prokaryotic cells have circular DNA.
Do eukaryotes have circular DNA in their cells?
No, eukaryotes do not have circular DNA in their cells. They have linear DNA organized into chromosomes within the nucleus.
How is the number of replication errors in cells kept to a minimum?
Cells have various mechanisms to ensure accurate replication and minimize errors. These include proofreading by DNA polymerase, DNA repair pathways, and cell cycle checkpoints that monitor DNA integrity. Additionally, telomeres at the ends of chromosomes help prevent loss of genetic information during replication.

What checks DNA for error?
DNA fingerprinting
How can a reporter enzyme monitor transformation of host cells by foreign DNA in addition to a selectable marker?
A reporter enzyme monitors transformation of host cells by foreign DNA in addition to a selectable marker through insertional inactivation. It differentiates recombinants from non recombinants.
Is the DNA in prokaryotic cells circular or eukaryotic cells?
The DNA in prokaryotic cells is circular, while the DNA in eukaryotic cells is linear.
Does DNA have cells?
no. Cells have DNA not the other way around
Quantification techniques can distinguish living cells from dead cells in a culture?
Quantification techniques such as fluorescent dyes, viability assays, and flow cytometry can distinguish living cells from dead cells in a culture. Living cells typically exhibit membrane integrity, metabolic activity, and intact DNA, whereas dead cells may show compromised membrane integrity and loss of cellular functions. These techniques provide valuable information about the viability and health of cells in a culture.
What is a DNA lesion?
A DNA lesion is a structural change to the DNA molecule that can lead to mutations or abnormalities in genetic information. Lesions can be caused by various factors such as environmental toxins, radiation, or errors during DNA replication. Repair mechanisms in cells help to correct these lesions to maintain genome integrity.
How is the DNA in your brain cells different from the DNA in your heart cells?
They use different DNA codes
Is it true or false that prokaryotic cells contain more DNA than eukaryotic cells?
False. Eukaryotic cells generally contain more DNA than prokaryotic cells. Eukaryotic cells have their DNA enclosed within a nucleus, whereas prokaryotic cells have their DNA located in the cytoplasm.
Is DNA replication the same as DNA repair?
No, DNA replication is the process by which a cell makes an identical copy of its DNA, while DNA repair refers to the mechanisms cells use to fix damaged DNA, such as DNA mismatches, breaks, or lesions. DNA replication occurs during the cell cycle to ensure accurate transmission of genetic information to daughter cells, while DNA repair helps to maintain genomic integrity by correcting errors and damage.
