DNA replication in human cells occurs at a rate of about 50 base pairs per second, and the length of the longest human chromosome (chromosome 1) is 249 Mb (1Mb = 1x10^6 bp).
If DNA replication took place continuously from one end of chromosome 1 to the other, it would take approximately:

A) 2 seconds.
B) 2 minutes.
C) 2 hours.
D) 2 days.
E) 2 months.

E) 2 months.

Explanation:

DNA replication is a process that takes place simultaneously at many sites (i.e., origins of replication) along the DNA sequence, which makes it incredibly fast. During replication, each DNA strand serves as template and they are used by a DNA polymerase to synthesize the new DNA molecules. DNA replication is semiconservative because each new double helix will have one old (original) and one new DNA strand

cramming before a final is bad because it makes a student's stress level higher. students who embrace cramming to get through a final exam week find themselves struggling to perform consistently, once the brain adjusts to prolonged sleep deprivation.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
