Below is a sequence from a template strand of DNA. Write the sequence of the mRNA that would be transcribed from this. Be sure to label the 3’ and 5’ ends. DNA:3’ A G G T C T T C A C 5’

mRNA:

In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.

Explanation:

Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.

The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.

In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

ADN   mRNA

T            A

C            G

G            C

For this reason:

DNA:    3’ A G G T C T T C A C 5’

mRNA: 5'-U C C A G A A G U G-3'

c. heat from the poles back down towards the equator.

if you listed your answers right then i believe your answer is b.
