Answer: DNA is a polymer of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base
Explanation:
Every molecule in the human body are formed by the chains of particular substances. These components are arranged orderly as linked chains to give the structure called DNA.
The components include nucleotides—this is also considered the chemical substance in the human body which helps in the formation.
In this formation of chains, nitrogenous bases will also be linked to form a polymer of DNA.
One type of atom
a pure substance
Answer:RNA polymerase binds to a sequence of DNA called promoter found near the beginning of the gene
Explanation: each gene has it own promoter. Once bound, RNA polymerase seperates the DNA strands, providing the single-stranded bind needed for transcription
