Diffrence b/w Coding strand and Template strand of DNA?

Question

From my studies about transcription, i was taught that one strand in DNA is template and other is coding strand.the RNA polymerase enzyme copies information from template strand,and coding strand does not take part in transcription.,and the name,coding srand is an anomaly.But,isnt information on coding strand being copied into mRNA,?to quote my text book:"strangely,this strand (with 5'-3' polarity,and opposite to template strand)which do not code for anything is called coding strand."
what is there to be so much strange?also,some source says that template strand is called as sense strand and the coding strand is called anti sense strand,while wikipedia says the opposite..please help.

Answer 1

•The coding strand (Sense strand) of DNA has the same sequence as the mRNA and is related by the genetic code to the protein sequence that it represents.

•The antisense strand (Template strand) of DNA is complementary to the sense strand, and is the one that acts as the template for synthesis of mRNA.

Answer 2

Coding DNA, exons, is used for making mRNA, and codes for amino acids.

Non-coding DNA, introns, only fills up the DNA strand.



Strands:

The "coding" strand is first made in to RNA, then processed to mRNA, then translated into amino acids --> polypeptides. It has a start- and stop codon.

The "non-coding" strand is only used as a template strand in replication, since it is complementary with the coding one.

Coding strand is that strand which has the same sequence as that of the newly transcribed mRNA. The direction of the coding strand is 5' to 3'. It is also called the sense strand or non template strand.

Non coding strand is that strand which has the sequence complementary to that of the newly transcribed mRNA. The direction of this strand is 3' to 5'. This is also called the template strand or antisense strand.

Answer 3

The term template strand refers to the sequence of DNA that is copied during the synthesis of mRNA.



The opposite strand (that is, the strand with a base sequence directly corresponding to the mRNA sequence) is called the coding strand or the mRNA-like strand because the sequence corresponds to the codons that are translated into protein.
