Question

2. What is a feature of transcription? * 1 point Both strands of a DNA molecule act as a template for mRNA. Nucleoside triphosphates become nucleotides by losing three phosphates. RNA polymerase binds to the promoter region. The sense strand acts as a template for mRNA.

Answer 1

The correct answer is ''RNA polymerase binds to the promoter region. ''

Step-by-step explanation:

The process of DNA transcription is the first step towards the formation of proteins from DNA. DNA transcription is the synthesis of mRNA (messenger RNA) from DNA that will later be translated to form proteins. RNA polymerase must recognize the starting point of synthesis. This area of ​​DNA, described as a promoter, consists of two short sequences of bases located 10 and 35 base pairs from the initial point of synthesis. By convention, to describe the region of DNA where the gene to be transcribed is located, the number +1 is given to the base pair (DNA) where RNA synthesis begins, up to + n, which will be the last base pair where synthesis ends. RNA polymerase is the enzyme that transcribes the sense strand of DNA into a messenger RNA molecule. This enzyme forms the phosphodiester bond in growing RNA by nucleophilic attack on the incoming nucleotide. It does not need a primer and synthesizes in the 5′-3 ′ direction.
