First, you must understand that a strand of mRNA, is the complement of one side (the left) of DNA. Basically, you take the one side of the DNA strand and complement it by using these pairs: Adenine:Uracil, Cytosine:Guanine, Thymine:Adenine.
They are all usually abbreviated by their first letter.
Second, in order to find the mRNA, you must understand the process of protein synthesis. If you know the process, then it should be clear that the mRNA is made from one side of the DNA strand during the transcription. It then moves out of the cell and into the cytoplasm to start translation.
Because DNA does not leave the nucleus, and protein synthesis occurs on the ribosomes in the cytoplasm and rough ER. The mRNA is able to leave the nucleus and go to the ribosomes.
cause they both have guanine, cytosine plus I am not sure I got this right so fingers cross
it makes the same exact strand
it makes the same exact strand
DNA is not made into mRNA, it is transcribed by mRNA. The DNA molecule is split into two strands by the enzyme helicase. One strand is the sense strand and the other is the anti-sense strand. Then mRNA nucleotides pair with their complimentary DNA bases on the antisense strand. The enzyme RNA polymerase causes the mRNA nucleotides to bond with one another, forming a strand of mRNA.
The strand running in the 3'-5' end will be the one that RNA copies, as this is the direction of transcription
mRNA is like a single strand instead of a double strand. If DNA is like a twisted ladder, then mRNA is like a single half of that ladder, with only half the bases.
The synthesis of mRNA from DNA is called transcription.

A strand of DNA
One mRNA strand is made.
There is no such process. DNA cannot come from RNA unless it contains reverse transcriptase. However, there is a process that makes mRNA from a DNA strand. This process is called transcription.

transcript
This is typically called the template DNA, which is the anti-sense strand of DNA. The strand that is not transcribed is called the sense strand.
separates the DNA strand and making a complimentary strand
An enzyme called reverse transcriptase, which creates a DNA strand from an mRNA strand.
