B 3 Lesson 5 flashcard

Front

What does identical chromosomes in non-cancer cells suggest about DNA replication?

Back

DNA replication is accurate and errors are corrected.

Front

How does a faulty version of p53 contribute to cancer development?

Back

Errors during DNA replication may not be corrected, leading to mutations that can cause cancer.

Front

How do chromosomes in non-cancer cells compare to each other?

Back

They are identical.

Front

What is a key characteristic of chromosomes in cancer cells?

Back

They have differences compared to each other.

Front

What is the role of p53 during DNA replication?

Back

It corrects errors.

Front

Define DNA replication.

Back

The process by which a cell makes an exact copy of its DNA.

Front

What is a mutation?

Back

A change in the DNA sequence that can lead to changes in protein function.

Front

What is the function of the p53 protein?

Back

To regulate the cell cycle and prevent the development of tumors.

Front

What happens if DNA replication is inaccurate?

Back

It can lead to mutations and potentially cancer.

Front

What is the significance of error correction in DNA replication?

Back

It helps maintain genetic stability and prevents mutations.
