15.Differentiate between template strand and coding strand of DNA. Name the source of energy forthe replication of DNA. (2) |
|
Answer» The main difference between template and coding strand is that template strand only serves as the template for transcription whereas coding strand contains the exact same sequence of nucleotides in the mRNA except thymine. The backbone of DNA strands is composed of sugar and phosphate groups. Theses groups are covalently bonded and to them in turn are bonded base nucleotides. These nucleotides bonds are what provide the immediate energy required for DNA synthesis. |
