Difference Between Template and Coding Strand
Template strand and coding strand refer to the two complementary strands of DNA that encode genetic information. The two strands in double-stranded DNA are referred to as the template and coding strands. The DNA strand known as the template strand serves as a blueprint for the production of RNA, whereas the coding strand is the other strand. The coding and template strands of a DNA structure are separate strands. There are just a few characteristics and functions that set them different.
Template Strand
The template strand is the non-coding DNA strand of a certain gene. The DNA template strand, also known as the anti-sense strand or the positive strand, is one of the strands that remain after being disclosed by the enzyme DNA helicase during the transcription process. This strand is read by RNA polymerase from 3′ to 5′. There is an anticodon in the template strand. It has identical nucleotide sequences as tRNA. The template strand serves as the starting point for the transcription of the mRNA, and the other strands choose the correct base sequence for the mRNA.
Coding Strand
The coding strand is the strand that acts as the non-template strand during transcription. The nucleotide bases in the mRNA base sequence will be the same as those in the coding strand, except thymine. Uracil is the nitrogenous base that takes the place of thymine in mRNA. Because it determines the RNA sequence that eventually codes for a certain amino acid sequence of a protein, the coding strand is also known as the sense strand. From the 5′ end to the 3′ end, this strand reads in the direction. Codons, which are nucleotide triplets that represent a specific amino acid in the polypeptide chain, are found on the coding strand.

FAQs on Coding and Template Strand
Q1: Define template strand.
Answer:
The template strand is the non-coding DNA strand of a certain gene. The DNA template strand is also known as the anti-sense strand or the positive strand. This strand is read by RNA polymerase from 3′ to 5′.
Q2: Write the similarities between the template and coding strand.
Answer:
Both template and coding strand are the composition of DNA molecules.
Q3: How do the coding strand and template strand vary from one another?
Answer:
The DNA strand that codes for the relevant gene is known as the coding strand. This is complementary to the template strand, which may be translated to create an RNA fragment with the same nucleotide sequence as the coding strand.
