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.
DNA polymerase adds nucleotides onto the 3'OH end of the preceding nucleotide and carries out synthesis in the 5' to 3' direction down the length of the DNA. The result of DNA polymerase function is two copies of DNA that contain one original and one newly synthesized strand of DNA.To unlock this lesson you must be a Study.com Member.he result of DNA polymerase function is two copies of DNA that contain one original and one newly synthesized strand of DNA.
