Changes in the dna are called mutations. They can occur spontaneously. Mutations can only be passed down in gametes--sperm and egg cells. with Darwins theory at mind a mutation needs to pass the test of natural selection to remain in the gene pool. So purposly making mutation or altercations may end in diseases/illnesses or in some cases death because they body can not take it.....hope this helps if it doesnt im sorry!
<u>Answer</u>:
Actions happens after transcription ends is "An mRNA molecule leaves the nucleus of the cell."
<u>Explanation</u>:
Transcription is the process of formation of mRNA from DNA. DNA is the genetic material which carries all the information for the formation of mRNA and then protein. Transcription occurs in nucleus, but as soon as the mRNA is formed it unwinds from the template DNA stand and moves into the cytoplasm for the next process i.e. translation. Translation occurs nearer to the ribosomes, it is the formation of protein from mRNA strand. combinedly transcription and translation are referred as the central dogma of the molecular biology.
The correct answer is option e, that is, the thermal energy that one feels when one put the hand on the ground originates from the Sun.
The Earth's energy budget holds for the equilibrium between the energy received by Earth from the Sun, and the energy Earth radiates back after having been dispersed all through the five constituents of the climate system of the Earth and having thus fueled the so-called heat engine of the Earth. This system comprises the Earth's water, atmosphere, ice, all living things, and rocky crust.
That part of the water cycle is called condensation....
