Answer:
Explanation:
Transcription takes place in nucleus in the presence of the enzyme RNA polymerase.
During transcription, the code present in DNA gets transcribed into the code in mRNA.  (messenger RNA)
RNA even though is a single stranded shows base pairing.
The pre-mRNA gets created from the DNA.
DNA has two strands, one of these strands acts as coding and another non coding strand.
The DNA shows base pairing with AGTC.   [A-Adenine, G- Guanine, T-Thymine and C- Cytosine]
Whereas mRNA base pairing with AGUC.  [ U- Uracil ]
Here in mRNA, instead of thymine, uracil gets paired.
According to base pairing of coding strand/sense strand of DNA, complementary bases pairs in 5'---->3' direction in mRNA.
The mRNA created looks exactly like the non-coding strand/sense strand of DNA except instead of thymine, uracil gets replaced.
The pre-RNA undergoes splicing, capping and tailing to form mature mRNA.
 
        
             
        
        
        
The krebs cycle 
I know this from a multiple choice question I helped my friend with lol
 
        
                    
             
        
        
        
I believe your answer is B, Because electrons are clinched to protons, most times, therefor there is not an electron microscope, but a ELECTRONIC Microscope will show the organism on a screen. hope that helped some<span />
        
             
        
        
        
Multidisciplinarity draws on knowledge from different disciplines but stays within their boundaries. Interdisciplinarity analyzes, synthesizes and harmonizes links between disciplines into a coordinated and coherent whole. 
 
        
             
        
        
        
Frogs have only one opening, called the cloaca, through which both feces and urine pass. Humans, however, possess two separate orifices for urine and feces to exit through.
