Practice DCP #2 (6E/5A/5B/5C/10A/10C/6G)

Front

What two body systems must directly interact for vertebrate organisms to exchange gases?

Back

Circulatory system and respiratory system.

Front

What does S phase represent in the cell cycle?

Back

The S phase is the part of the cell cycle where DNA is replicated.

Front

What is the direct result of an error in the transcription of a DNA nucleotide?

Back

A codon sequence is incorrect.

Front

How do the circulatory and respiratory systems interact in the human body?

Back

The respiratory system brings oxygen into the lungs, where it diffuses into the blood in the circulatory system, and carbon dioxide is expelled from the blood into the lungs to be exhaled.

Front

What stage of mitosis is characterized by chromosomes lining up in the middle of the cell?

Back

Metaphase.

Front

What is the primary function of the circulatory system?

Back

To transport nutrients, gases, hormones, and waste products throughout the body.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA transports amino acids to the ribosome, where they are assembled into proteins.

Front

What happens during the G1 phase of the cell cycle?

Back

The cell grows and synthesizes proteins necessary for DNA replication.

Front

What is the function of the nuclear membrane?

Back

To protect the nucleus and regulate the passage of materials in and out of the nucleus.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.
