What Is The Core Enzyme In RNA Polymerase? The Escherichia coli RNA polymerase (RNAP) is a multi-subunit enzyme composed of five subunits including α (two copies), β, β’ and ω subunits. These five subunits form the RNAP core enzyme responsible for RNA synthesis using DNA as template and ribonucleotide (rNTP) as substrate. Which of the
Is RNA An Exact Copy? Eukaryotic mRNA molecules are usually composed of small segments of the original gene and are generated by a process of cleavage and rejoining from an original precursor RNA (pre-mRNA) molecule, which is an exact copy of the gene. Is DNA or RNA an exact copy? The rules of complementarity in
Where Does RNA Carry Genetic Information? The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in
Where Is Ribonuclease Found? RNases are present in all organisms, including bacteria, yeast, plants, and animals, and in almost all tissues and body fluids of mammals. Some RNases are secreted (extracellular), probably suggesting their major roles in digestion. Where are RNase found? RNases, which play important roles in nucleic acid metabolism, are found in both
Is RNA The Same As DNA? There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine. Is DNA and RNA identical? Structurally,
What Are The 3 Basic Building Blocks Of DNA? DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. What are the 3 main building blocks of DNA? Every nucleotide is made of three
Which Best Compares DNA And RNA With Regard To The Process Of Protein Production? Which best compares DNA and RNA with regard to the process of protein production? DNA transforms from a nucleic acid into a protein, and RNA remains a nucleic acid. … DNA leaves the nucleus during the process and RNA remains in
