Asthma is a common long term inflammatory disease of the airways of the lungs. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and bronchospasm. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. These episodes may occur a few times a day or a few times per week. Depending on the person they may become worse at night or with exercise. Asthma is thought to be caused by a combination of genetic and environmental factors.
DNA polymerase III (not DNA polymerase) is an enzyme that works in association with other enzymes during the replication of a DNA molecule. DNA replication begins when the enz â¦ yme, known as helicase unwinds a DNA strand.Helicase unwinds a DNA strand, thus, in the process, separating the two DNA templates. polymerase is an enzyme that catalyzes the conversion of free nucleotides into a single strand.   DNA polymerase differs from RNA polymerase in two major respects:   * â¦ Like all enzymes, DNA polymerase is substrate-specific.
Answers. Best Answer: RNA polymerase is used in Transcription while Helicase is used in DNA replication. RNA polymerase is an enzyme that will help to unwind the double stranded DNA by breaking the hydrogen bonds between complementary bases.Basically, RNA polymerase is a wonderful enzyme which does all the work from breaking to adding complementary RNA nucleotides.NA polymerase is an enzyme that will help to unwind the double stranded DNA by breaking the hydrogen bonds between complementary bases. Basically, RNA polymerase is a wonderful enzyme which does all the work from breaking to adding complementary RNA nucleotides.
