Given the following DNA template, what is the appropriate mRNA strand
3' TACTTCAAACCGATT 5'

5' AUGAAGUUUGGCUAA 3'

Explanation:

The process by which the information encoded in a DNA is used as a template to synthesize a mRNA is called TRANSCRIPTION. It is the first stage of gene expression carried out in the nucleus of eukaryotic cells and cytoplasm of prokaryotic cells by RNA polymerase enzyme.

The process of transcription follows the complementary base pairing rule, which says that Adenine base always hydrogen pairs with Thymine while Guanine pairs with Cytosine. During transcription, the Thymine base (T) is replaced by Uracil base (U). Hence, whenever RNA polymerase reads an A in the DNA, it synthesizes U in the mRNA and vice versa for T and A. The same applies for G and C.

For the DNA sequence;

3' TACTTCAAACCGATT 5'

The mRNA sequence will be synthesized;

5' AUGAAGUUUGGCUAA 3'

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

answer: c.
