cells III

Cancer primarily involves uncontrolled __________ of cells.

Division

A mass of rapidly replicating cells is called a __________.

Neoplasm

Benign tumors are __________, whereas malignant tumors are not.

Encapsulated

Malignant tumors can __________, meaning they can spread throughout the body.

Metastasize

Cancer cells can lead to a depletion of __________ in the body due to their rapid growth.

Nutrients

During DNA replication, the enzyme __________ unwinds the DNA double helix.

Helicase

The process of making mRNA from DNA is called __________.

Transcription

In the ribosome, the site where the tRNA holding the growing polypeptide chain is located is the __________ site.

P (peptidyl)

A __________ mutation is when a change in the DNA sequence creates a stop codon early, terminating protein synthesis.

Nonsense

The three primary enzymes involved in DNA replication are helicase, __________, and ligase.

Polymerase

What causes cancer to develop in the body?

Cancer develops primarily due to uncontrolled division of cells, leading to the formation of neoplasms.

What is a neoplasm?

A mass of rapidly replicating cells.

What is the difference between benign and malignant tumors?

Benign tumors are encapsulated, whereas malignant tumors are not.

What does it mean for malignant tumors to metastasize?

It means they can spread throughout the body.

How do cancer cells affect the body's nutrients?

They can lead to a depletion of nutrients in the body due to their rapid growth.

What is the role of helicase in DNA replication?

Helicase unwinds the DNA double helix.

What process converts DNA into mRNA?

The process is called transcription.

Where is the peptidyl site located?

It is located in the ribosome where the tRNA holds the growing polypeptide chain.

What is a nonsense mutation?

A mutation that creates a stop codon early, terminating protein synthesis.

Name the three primary enzymes involved in DNA replication.

Helicase, polymerase, and ligase.

What is the primary cause of cancer development in the body?

Uncontrolled division of cells, leading to the formation of neoplasms.
