Detailed explanation-1: -Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell ‘s activities, while RNA converts that code into proteins to carry out cellular functions.
Detailed explanation-2: -All organisms contain DNA and RNA. What are the subunits of DNA and RNA? nucleotides.
Detailed explanation-3: -A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).
Detailed explanation-4: -The RNA polymerase core enzyme consists of two molecules of the subunit and one molecule each of the and ′ subunits. The two subunits are considered to contact the other subunits differentially and thus to play different roles in RNA polymerase assembly and plausibly also in transcription regulation (1, 6).
Detailed explanation-5: -A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand.
