Answer:
T A A G T C G C T
Explanation:
DNA strand: A T T C A G C G A
complementary DNA strand: T A A G T C G C T
This is a very important rule:
Four kinds of nitrogenous bases in DNA: Adnine (A), Thymine (T), Guanine (G), Cytosine (C)
And this is how they're coupled:
A = T
C = G
For example::
First DNA strand: A T G C
complementary strand: T A C G

Energy is ever-existing - energy does not disappear or is not created from nothing. Energy is only transferred from one system to another. Energy is only transformed from one type/form of energy to another type/form of energy. So, the energy of a system is either converted into another type of energy in that same system or is extinct to another system.
1. The correct answer is: a. There are more mRNA bases than amino acids.
The transcription of monocistronic mRNA in prokaryotes is a rare process (it is more characteristic for the eukaryotes). Monocistronic mRNA is RNA, which encodes for only one or specific protein. Three bases of mRNA encode one amino acid of protein, thus it has more bases than amino acids of the final product, protein.
2. The correct statements are:
The mRNA contains 5' and 3' untranslated regions.
The stop codon does not code for an amino acid.
The start site of transcription is upstream of the start codon.
Each codon contains 3 RNA bases.
All of these approve that more bases are in mRNA since not all of them are translated into amin oacids.
Other statements are hallmarks of eukaryotic RNA processing, and therefore not relevant to prokaryotes.
