Exam 3: Cells

The Golgi apparatus consists of two small rods that play an important role in cell division.

Which are extremely fine hairlike structures on the surface of the cell?

If the messenger RNA code is adenine - uracil - cytosine,the transfer RNA bringing the amino acid would have which code?

Define or explain passive transport and active transport and give an example of each.

Because of specific base pairing,if one side of the DNA molecule has the nucleotide sequence of adenine - guanine - adenine - cytosine - thymine,the other side would be

Match each phase of mitosis to its corresponding description. -the chromosomes are aligned in the middle of the cells

The passive transport of material across the cell membrane requires the breakdown of ATP.

Lysosomes are the "digestive bags" of the cell.

List the stages of mitosis and explain what occurs in each phase.

The terms interstitial fluid and tissue fluid refer to the same thing.

The nucleus is the only structure in the cell that contains DNA.

Active transport moves material by a mechanism that is opposite that of diffusion.

If a messenger RNA molecule contains the sequence uracil - adenine - cytosine,what would be the nucleotide sequence for the transfer RNA it would attract?

If the DNA code is adenine - thymine - guanine,the messenger RNA sequence would be

DNA replication occurs during which phase?

The inability of the cell membrane to control the movement of the chloride ion into and out of the cell is the cause of both cystic fibrosis and cholera.

During which phase of mitosis does a cleavage furrow begin to appear?

If the DNA code is adenine - thymine - cytosine,the messenger RNA code would be thymine - adenine - guanine.

Which are rod-shaped structures that are important in cell division?

Which organelle contains its own DNA molecule?
