"What is the maximum rate of DNA replication in E. coli (e. g., the rate at which DNA polymerase incorporates new nucleotides into a polynucleotide chain)?"

1000 nucleotides per second.

Explanation: DNA polymerase is an enzyme that catalyzes the addition of new nucleotides to a polynucleotide chain during replication. The rate at which DNA polymerase adds new nucleotides to the growing polynucleotide chain before the DNA polymerase dissociates is called processivity. In E.coli, the rate at which DNA polymerase adds new nucleotides to the growing polynucleotide chain is 1000 nucleotides per second.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
