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.
Basically, RNA polymerase's role is very similar to that of DNA polymerase. RNA polymerase is an enzyme that is used during transcription in the nucleus. Similar to DNA polyme â¦ rase, RNA polymerase codes for the complementary nucleotides to a DNA strand.NA polymerase creates a strand of DNA from a template strand of DNA. it is used to create a new copy of the DNA. In order to begin DNA synthesis, a primer is necessary. The primer is a short oligo nucleotide fragment that hybridizes to the template strand of DNA (the strand which is to be copied).
