Why is mRNA made from DNA? Hint: What can it do that DNA cannot do?

Once RNA polymerase is done, the mRNA transcript has to be processed before it can make its journey out of the nucleus and to the ribosome.

Explanation:

double compared to single

Explanation: NA is made up of deoxyribose sugar while mRNA is made up of ribose sugar. DNA is present in the nucleus while mRNA diffuses into the cytoplasm after synthesis. DNA is double-stranded while mRNA is single-stranded.

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs

not necessarily. higher fitness requires the organism to be reproductive successful. for example, an organism at age 10 with 15 offspring is much more fit than an organism at age 15 with only 5 offspring.
