What Is A Coding Strand

Key Difference – Template vs Coding Strand

In many organisms, DNA acts as the information store, while RNA acts as the messenger. The process of the synthesis of RNA from Deoxyribonucleic acid is known as transcription, which controls the gene expression and the product of proteins in many biological systems. In this process, two Dna strands are given specific names based on their involvement. Template strand is the Dna strand that acts as a template for RNA synthesis while the other strand is called coding strand. The key difference between these 2 strands is that template strand possesses the opposite base sequence of RNA while coding strand possesses the same base sequence of RNA (with the exception of thymine instead uracil). Not all DNA strands in a cell are transcribed into RNA. Transcription synthesizes all the types of RNA including mRNA, tRNA, rRNA, snRNA, miRNA and siRNA. There are few differences of RNA transcription amid prokaryotes and eukaryotes. For example, in eukaryotes, transcription process is much more complicated than in prokaryotes due to the involvement of a large number of transcription factors. Even so, the objective of this article is to express the divergence betwixt template strand and coding strand.

What is Template Strand?

Template strand is the DNA strand, which acts every bit the template for the synthesis of RNA. RNA polymerase reads this strand from 3' to v.'Template strand does not involve in coding, therefore, referred to as non-coding strand. The nucleotide sequence of the template strand is complementary to the mRNA molecule and the coding strand.

What is Coding Strand?

Coding strand determines the sequence of RNA strand. Coding strand has the same nucleotide sequence of RNA with the exception of Uracil instead of Thymine. Coding strand is besides referred to as sense strand because it determines the RNA sequence that ultimately coded for a particular amino acrid sequence of protein. This strand reads in the director from 5' cease to the iii' cease. v' end contains the phosphate group attached to 5' carbon atom, whereas three' end has the phosphate group attached to 3' carbon atom or hydroxyl group if is at the end of Deoxyribonucleic acid chain.

What is the divergence between Template and Coding Strand?

Function:

Template Strand: Template strand human action as the template for RNA synthesis.

Coding Strand: Coding strand has the same sequence of the newly synthesized RNA.

Other Names:

Template Strand: Template strand is also called antisense strand or [-] strand.

Coding Strand: Coding strand is known equally sense strand, [+] or nontemplate strand.

Base Sequence:

Template Strand: Template strand is complementary to the RNA that is synthesized.

Coding Strand: RNA sequence is equal to the coding strand of Deoxyribonucleic acid with the presence of Thymine instead of Uracil.
