Answer #1

Answer-

Option A)– check dna damage , health and viability of the cell, and resources for division of growth .

In G1 phase the cell is assessed if it is large enough for division and if there is reserve nutrients and growth factors for cell to divide.

Errors in dna replication is assessed in G2 checkpoint.

chromosomal attachment and alignment to the spindle apparatus is assessed at the spindle checkpoint or M checkpoint.

If this helps please give it a positive rating thank you !

Which of the following about cell cycle control is true? The concentration of cyclins changes as Cdk concentration changes. Decreasing cyclin concentrations would increase progression through cell cycle check points. Cyclins help activate cdks by phosphorylating them. Phosphorylation of retinoblastoma will increase progression through the G1/S cell cycle check point. Bipolar attachment of chromosomes to the spindle controls the transition from G1 to S.

Which of the following is the most likely effect of a mutation in the gene coding for a DNA repair enzyme? - The cell containing the mutation will divide more frequently because the cell cycle checkpoints will not function properly. - Mutations will accumulate more quickly because the cell will not be able to fix errors in replication. - The mutated gene will not be transcribed because RNA polymerase cannot transcribe mutated DNA. - The cell will immediately undergo apoptosis...
