According to the website www.tutorvista.com‚ Prokaryotes differ from eukaryotes in their structure‚ packing‚ density‚ and arrangement of their genes on the chromosome. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the cell wall‚ and the structure of chromosomal DNA. All cells share some common characteristics that make them living things and all organisms are composed of cells which are the basic fundamental unit of life.

BS801 Genes R Us Questions for study: 1. What functions do transcription and translation carry out‚ and where are they carried out in the cell? Transcription: process of creating an equivalent RNA copy of a sequence of DNA Transcription is the first step leading to gene expression. The stretch of DNA transcribed into an RNA molecule is called a transcription unit and encodes at least one gene. Occurs in nucleus of the cell Translation: Translation is the production of proteins by decoding mRNA produced

appearance. Formed as an extension to the nuclear envelope‚ the ribosomes deposit their proteins directly into the RER where they are ’pinched off’ as transport vesicles to be transported throughout the cell‚ to the Golgi complex or beyond.

environment. Carries ribosomes that are responsible for the production of proteins (rough). Synthesis lipids from fatty acids and glycerol and transports these to the Golgi body (smooth). Ribosomes – This binds to the rough endoplasmic reticulum and to the mRNA. It also enables translation of mRNA to produce proteins. Golgi apparatus – Receives proteins from the ribosomes via endoplasmic reticulum and chemically modifies them for export (particularly in secreting cells). Produces vesicles to transport
