you count 60 onion cells in different stages of mitosis. of those 60, 19 are in prophase, 14 in metaphase, 12 in anaphase, and 15 in telophase. if a full cycle is 24 hours (1440 minutes), which stage has the longest duration and how long is it in minutes?

Respuesta :

Using the ratio concept, prophase, which lasts 456 minutes, is the longest stage.

How to determine the Mitosis stage?

The following formula can be used to determine how long each Mitosis stage lasts:

Total time spent = (Number of onions per step / total onions).

Total time spent = (60 x 24) = 1440 minutes in 24 hours.

Duration of each stage:

Anaphase:

(12/60) x 440=288 minutes

Prophase:

19/60 times 1440 equals 456 minutes.

Metaphase:

(14/60) x 1440 equals 336 minutes.

Telophase:

15 / 60 equals 1440 minutes.

Therefore, because of this, the prophase stage has the longest length, lasting 456 minutes.
