Chapter 1, Problem 8P
Summary Introduction
To determine: Whether ribosomal RNA genes were “born” perfect.
Introduction:
Ribosomes are complex organelles found in all living cells that have function in protein synthesis. They contain two subunits, which is composed of protein, and a type of RNA, known as ribosomal RNA (rRNA). Prokaryotic ribosomes consist of 30S subunit (small subunit) and 50S subunit (large subunit) which together make up the complete 70S ribosome. 30S subunit is consists of 16S ribosomal RNA and 21 polynucleotide chains, while 50S subunit is composed of two rRNA species, the 5S and 23S rRNAs.
