MRNA aka messenger rna is what is created to "transcribe the dna". Since dna cannot leave the nucleus, it must somehow give its information a different way. What happens is that DNA opens and different nucleotides form together with the bases that are now open. This form is called mRNA. mRNA now takes this information, travels outside the nucleus to the ribisomes. Here the information is read and proteins are synthesized. In conclusion mRNA is needed to transfer the info out of the nucleus
Helps create the structure
Most like mitochondria it is always the energy storer
Evolution. allele frequencies change so characteristics change and if this is over time it is evolution- "the change over time of allele frequencies"
