1) What must occur for a strand of double-helix DNA  before it can transcribe itself into RNA is the DNA must unwind its double- helix near the gene that is going to be transcribed. This region that the DNA has opened up is called transcription bubble.  

2) The two key differences between DNA and RNA is that DNA contains  sugar deoxyribose, while RNA contains sugar ribose. The second key difference is DNA's nitrogen bases are adenine, cytosine, guanine and thymine ( A, C, G, T )  while in RNA instead of thymine there is the uracil base.

( A, C, G, U )

3) The reason DNA transcribes itself into RNA because that is the whole goal of the process called transcription where a strand of DNA is copied into a new molecule of mRNA ( messenger RNA ) to to construct a functional product such as a protein.

4) A error during the process of transcription can change how the organism's  physical characteristics or also can impact the way how DNA codes the phenotype. The name that was given for this situation is called a Mutation.

5)  DN: ATTCGCACT > RNA: AUUCGCACU

( DNA: A, G, C, & T while RNA: A, G , C , & U )

( DNA: A = T, G = C)  (RNA: A = U, G = C)

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).
