Front

What is the primary way to prevent viruses from mutating into new variants?

Back

Prevent the virus from replicating and mutating.

Front

What is the mRNA sequence transcribed from the DNA template TGG CAA GTA CGT?

Back

UGG CAA GUA CGU.

Front

During which phase of the cell cycle does DNA replication occur?

Back

S phase.

Front

What happens to UV intensity as you travel away from the equator?

Back

The intensity decreases.

Front

What are undifferentiated cells that can become specialized types of cells called?

Back

Stem Cells.

Front

What is the function of stem cells in the body?

Back

Stem cells can differentiate into various specialized cell types.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is when DNA is replicated, ensuring each daughter cell receives a complete set of chromosomes.

Front

How do viruses replicate?

Back

Viruses hijack the host cell's machinery to replicate their genetic material and produce new virus particles.

Front

What is the relationship between UV intensity and skin cancer risk?

Back

Higher UV intensity increases the risk of skin cancer due to DNA damage in skin cells.
