Question

1. a mutation prevents the g1 checkpoint from functioning properly. which outcome is most likely? cells will pause longer in g1 and fail to divide. cells may enter s phase with damaged dna, increasing the risk of cancer. cells will skip mitosis entirely and grow larger. cells will stop at g2 until dna is repaired.

Explanation:

The G1 checkpoint checks for cell - size, nutrients, growth factors, and DNA damage before allowing the cell to enter the S phase (DNA replication phase). If it malfunctions, cells may proceed to S phase even with damaged DNA. This can lead to mutations and an increased risk of cancer development.

Answer:

Cells may enter S phase with damaged DNA, increasing the risk of cancer.
