Assuming that each replication fork moves at a rate of 500 base pairs per second, how long would it take to replicate the e. coli chromosome (with 4.6 million base pairs) from a single origin of replication?

seconds

hours

Explanation:

Given,

Rate of movement of replication fork across the base pair is equal to base pair per second.

The total number of base pair in the chromosome of an e. coli bacteria million

Now, time taken by replication fork to replicate the entire e. coli chromosome

is equal to total number of base pairs in the chromosome of an e.coli bacteria divided by the rate of replication

seconds

hours

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
