2024 Biology Fall Final Review

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the only molecule that moves during osmosis?

Back

Water.

Front

What is the optimal temperature for enzyme activity?

Back

The optimal temperature is the temperature at which an enzyme functions most efficiently, often around 40°C for many enzymes.

Front

What are the lytic and lysogenic cycles in viruses?

Back

The lytic cycle results in the destruction of the host cell and the release of new viruses, while the lysogenic cycle allows the virus to integrate into the host's DNA and remain dormant.

Front

What is the difference between the lytic and lysogenic cycles?

Back

Lysogenic is dormant; Lytic shows immediate symptoms.

Front

What is complementary DNA?

Back

Complementary DNA is the strand of DNA that pairs with a given DNA sequence, following base pairing rules (A-T, C-G).

Front

What is the complementary DNA strand for AGG-TAA-CCA?

Back

TCC-ATT-GGT.

Front

What is the longest phase of the cell cycle?

Back

Interphase.

Front

What occurs during interphase?

Back

During interphase, the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What is the G1 phase?

Back

The G1 phase is the first stage of interphase where the cell grows and synthesizes proteins necessary for DNA replication.
