Ribosomes produce about 2,000 proteins per second or 173,000,000 per day. Astounding beyond all reason. Multiply that by the number of cells in the human body, and you get 1.28x10 to the 21 proteins manufactured each day. Cells also destroy the same number. They are constantly renewing and replacing their proteins.

What two organelles are involved in protein synthesis?
Ribosomes produce proteins and proteins are produced very quickly. There are two kinds of ribosomes: Bound and Free The second organelle is the nucleolus where RNA is synthesized and assembled from proteins. Both are part of the nucleus which is part of the ER system
What is making a real protein?
To make a protein, a cell goes through two processes, the first one is transcription and the second is translation. In the first stage, DNA helicase unwinds and unzips the two strands of a DNA double helix. Then DNA polymerase comes in and helps make a complementary strand called messenger RNA of mRNA. this mRNA is then cut up to the bare essentials, thus containing pretty much only the nucleotides coding for genes. Splicosomes are the molecules that do this cutting, known as splicing, which then makes the mRNA ready for action. The mRNA then travels outside of the nucleus, and finds a transfer RNA of tRNA molecule. The next step is translation, in which the actual building of the protein takes place. First off, the mRNA molecule is floating around, until it meets a ribosome. This ribosome is the site at which this mRNA will meet a tRNA molecule, containing a nucleotide sequence complementary to that of the mRNA. This tRNA has this nucleotide sequence at one end, and an amino acid on the other end. This amino acid is then put into the ribosome, into the A site of the ribosome. It then moves to the P site, where the polypeptide chain, or building of the protein is actually taking place. This amino acid is then adjoined to the chain, and is then part of the protein molecule. Once all of the necessary amino acids are joined in, the protein moves to the E site, where it exits the ribosome. This molecule is then complete, and will then proceed to the part of the cell where it is needed, and will start to function.
What are the two steps in the process of going from DNA to protein?
A process known as protein synthesis. The mRNA must be transcribed in the nucleus using DNA as a template, then must be moved to the cytoplasm and to the ribosome where translation forms a protein. For more information, follow the related link below.

Where does the messenger RNA go?
When mRNA leaves the nucleus, it goes to the ribosomes - where it is "translated" into a sequence of amino acids that form a protein. The mRNA contains 3-base codes, which bind with a tRNA carrying a specific amino acid. When these bind, the amino acid is joined to a chain. At the end of translation this chain is a protein. This process all occurs in the ribosome.

Is protein kinase a second messenger involved in cellular signaling pathways?
No, protein kinase is not a second messenger in cellular signaling pathways. It is an enzyme that plays a key role in transmitting signals within cells by adding phosphate groups to proteins. Second messengers are small molecules that relay signals from cell surface receptors to target molecules inside the cell.

3 steps of protein synthesis?
Transcription: DNA is used as a template to make a complementary RNA molecule. Translation: The mRNA produced during transcription is used to synthesize a specific protein by ribosomes. Protein folding and modification: The newly synthesized protein undergoes folding and post-translational modifications to become functional.

What two steps must occur in protein synthesis?
The two main steps in protein syntheis are transcriptionand translation. In transcription, the enzyme RNA Polymerase uses a DNA strand as a template to make a transcript of messenger RNA. This transcript is then translated into protein by the ribosome.
What Proteins are synthesized?
During protein synthesis, or translation, is a process that uses a messenger RNA transcript that is translated by a ribosome. Charged tRNAs carry new amino acids to the ribosome-mRNA complex. These amino acids are added to a growing polypeptide chain, with each amino acid being specifically added based on a three-nucleotide base mRNA codon-tRNA anticodon association.
What is trna and what does it function?
tRNAs are small RNA molecules that carry amino acids to growing polypeptide chains that are being made in a ribosome. The have anti-codons that are complimentary to the codons on the mRNA. They carry an amino acid that is specific to their anti-codon.
What best describes the introduction of a human gene into bacteria to induce the bacteria to produce a desired human protein?
Recombinant DNA technology, DNA is inserted into bacteria, it can be used to make large quantities of the desired protein., and it had its origins in two related fields. the first, microbial genetics, studies mechanisms by which microorganisms inherit traits. the second, molecular biology, specially studies how genetic information is carried in molecules of DNA and how DNA directs the synthesis of protein.

What is the minimum number NTPs requred for formation of one peptide bond during protein synthesis?
Two NTPs are required for the formation of one peptide bond during protein synthesis. Specifically, one NTP is needed for charging the tRNA with the corresponding amino acid, and a second NTP is required for the actual bond formation in the ribosome.
