Many times the definition is linked to the retirement age, which in some instances, was lower for women than men. This transition in livelihood became the basis for the definition of old age which occurred between the ages of 45 and 55 years for women and between the ages of 55 and 75 years for men. (Thane, 1978).
RNA polymerase is the protein that makes the copy of DNA. Ribosomal RNA (rRNA) is part of the ribosome, or protein builders of the cell. Ribosomes are responsible for translation or the process our cells use to make proteins. rRNA are responsible for reading the order of amino acids and linking amino acids together. They do this through a highly complex sequence.
Best Answer: RNA polymerase synthesizes RNA, but does not need a primer to initiate synthesis. DNA polymerase synthesizes DNA, but needs a primer in order to initiate synthesis.DNA = Deoxyribonucleic Acid (H) RNA = Ribonucleic Nucleic Acid (OH) DNA is double stranded RNA is single stranded DNA uses Thymine as a base RNA uses Uracil as a base.Source(s):here are two main segments of the RNA polymerase molecule: the core enzyme, and the sigma subunit. These two pieces are together referred to as the holoenzyme.
