Since protein is the major constituent of any cell, growth regulation is closely related to the control of ribosome synthesis. In fact, the number of ribosomes per. Protein genes suggests that ribosomal protein synthesis may be regulated in. 1980, to control for differential loading of RNA on each gel lane. Because the. Ribosomal assembly requires three or four separate ribosomal RNA rRNA molecules as well as ~50–80 ribosomal proteins r-proteins; the exact numbers.

RNA polymerase reads the coding strand of the DNA and synthesises RNA that is

The entire protein would actually require a much longer sequence of DNA bases.
Whenever a protein needs to be made, the correct DNA sequence for that protein is copied to a molecule called (mRNA).

Protein synthesis :: DNA from the Beginning

DNA transcription is the process of making a single strand complementary RNA copy of DNA. Data is copied from the DNA to the RNA with the aid of the enzyme RNA polymerase. Using this process, the genetic information stored in the DNA is carried in the form of RNA to other parts of the cell. In eukaryotic cells a gene begins with a promoter region and an initiation code and ends with a termination code. However, the intervening gene sequence contains patches of nucleotides that have no meaning. If they were used in protein synthesis, the resulting proteins would be worthless. Eukaryotic cells prune these segments from the mRNA after transcription. RNA polmerase synthesizes a strand of pre-mRNA that initially includes copies of the meaningful mRNA coding sequences (exons) and the meaningless mRNA coding sequences (introns). Soon after its manufacture, this pre-mRNA molecule has the meaningless introns clipped out and the exons spliced together in the final version of mature mRNA

DNA: Structure, Replication and Protein Synthesis by …

Protein is complete and falls off of the ribosome
Our mug is now not only empty, but it is gone all together

Now go replicate your DNA!
Well, not really, although your DNA is replicating right now without your help.

DNA, RNA and Protein Synthesis - Modesto Junior College

DNA replication requires many enzymes. In eukaryotic cells an enzyme breaks the hydrogen bonds between the bases of the two strands of DNA in hundred of different forks along the length of the DNA. Proceeding in opposite directions on each side at each fork, enzymes known as DNA polymerase move along the length of the DNA, bonding new DNA triphosphate nucleotides into position.

DNA and Protein Synthesis PowerPoint Lesson and Notes

I mean, replicate the strand of DNA on your desk.

Read about mutations on your handout.


The purpose of this exercise is to become familiar with the structure of nucleic acids, DNA, RNA and to reinforce the role of DNA and RNA in the process of protein synthesis.

Control of ribosomal protein synthesis

Most enzymes are proteins, but RNA
molecules can be enzymes too.

The ribosome is not only complex, but it is also the most important part of the biological cell, along with the necessary information
needed to make proteins (encoded in DNA or RNA).
