Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.

So how does protein synthesis make hair? If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein.

For natural cells, the so-called central dogma of molecular biology describes how protein synthesis occurs through transcription and translation of genetic information in the cell. In the process ...

This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA).

However, in the half-century since the structure of DNA was first elaborated, scientists have learned that RNA does much more than simply play a role in protein synthesis. For example, many types ...

The Steps of Protein Synthesis In prokaryotes like bacteria, transcription and translation can occur simultaneously in the ...

Within a cell, DNA carries the genetic code for building proteins. To build proteins, the cell makes a copy of DNA, called mRNA. Then, another molecule called a ribosome reads the mRNA, translating it ...

In addition to exporting materials out of the nucleus, the protein, called Exportin-1 (also called Xpo1 or Crm1), seems to play a role in promoting gene transcription, the process that creates RNA ...

RNA synthesis, or transcription, is the process by which RNA is produced ... where it serves as a template for protein synthesis. Some RNA molecules, called ribozymes, possess catalytic activity and ...

My laboratory studies the regulatory and structural roles of mRNAs in the cytoplasm. Specifically, we investigate how 3′UTRs regulate protein functions in a manner that is independent of protein ...

Two molecular control factors play a decisive role in what is known as splicing, the cutting and assembly of mature messenger RNA—a prerequisite for protein synthesis in the cell. The poorly ...
