To understand how gene expression is regulated, we must first understand how a gene codes for a functional protein in a cell.

What is the difference between Prokaryotic and Eukaryotic Cells?

Let us make an in-depth study of transcription synthesis of RNA in prokaryotes and eukaryotes. In prokaryotic organisms transcription occurs in three phases known as initiation, elongation and termination. This form is called the holoenzyme. Transcription cannot start randomly but must begin specifically at the start of a gene. Signals for the initiation of transcription occur in the promoter sequence which lies directly upstream of the transcribed sequence of the gene. The exact sequences can vary between promoters but all conform to an overall pattern known as the consensus sequence.

The general process of transcription can be applied to both prokaryotic cells and eukaryotic cells. The basic biochemistry for each is the same; however, the specific mechanisms and regulation of transcription differ between prokaryotes and eukaryotes. This section will compare the process and regulation of prokaryotic and eukaryotic transcription. Although they are responsible for the production of different RNA molecules, all eukaryotic RNA polymerases are homologous to one another and to prokaryotic RNA polymerase 2. In both prokaryotes and eukaryotes, transcription begins with the binding of transcription factors to the promoter site on the DNA.

The DNA-protein interactions play vital roles in the central dogma of molecular biology. Proper interactions between DNA and protein would lead to the onset of various biological phenomena like transcription, translation, and replication. However, the mechanisms of these well-known processes vary between prokaryotic and eukaryotic organisms. The exact molecular mechanisms of these processes are unknown. Therefore, it is of interest to report the comparative estimate of the different properties of the DNA binding proteins from prokaryotic and eukaryotic organisms.

Genome Size Comparison. • Prokaryotes are generally in the ~ bp size range – see Genome Sizes. • Eukaryotes are more in the ~ bp size range.

In , Robert Hook discovered a cell. Some cells have membrane-bound organelles and some do not have. Depending upon the internal structure of the cell, two types of cells are found in an organism namely Eukaryotic and Prokaryotic. What is the difference between Prokaryotic and Eukaryotic cells?

To understand how gene expression is regulated, we must first understand how a gene becomes a functional protein in a cell.

Поскольку для одновременного подрыва устройств была необходима точнейшая координация действий, все эти изделия были связаны между собой телефонными линиями через Интернет. Двое суток встроенные часы устройств обменивались бесконечными потоками зашифрованной синхронизирующейся информации. АНБ, перехватывая эти информационные импульсы, игнорировало их, считая аномалией сети, безобидной тарабарщиной. Но когда ТРАНСТЕКСТ расшифровал эти потоки информации, аналитики тут же увидели в них синхронизированный через Интернет отсчет времени. Устройства были обнаружены и удалены за целых три часа до намеченного срока взрыва.
