An eukaryotic mRNA has 2 ends, a 3' (three prime) end and a 5' (five prime) end. They are both protected from degradation. The 3' end is protecting by a long tail of the Adenosine base, this tail is reffered to as the Poly-A tail and is established through the process of polyadenylation. The 5' end has a different method of protection from degradation, it undergoes "capping". Capping involves a Gaunine base paring in a 5' - 5' manner with the exposed 5' end of the mRNA. This basically leaves no exposed 5'. An eukaryotic mRNA has 2 ends, a 3' (three prime) end and a 5' (five prime) end. They are both protected from degradation.

∙ 10y agoThe 5 cap function helps to prevent mRNA degradation. It is a specially altered nucleotide on the 5 end of the precursor messenger RNA and other RNA transcripts existing in nucleotides.
The capping ensures the mRNA stability when it undergoes translation in the process.

Does DNA control the production of enzymes?
Yes DNA contains the "blueprints" of the cell, everything the cell makes it does with directions from DNA thank you so much!
What organelle synthesized protein?
Ribosomes.The only organelle that make proteins is ribosomes. DNA is the genetic material that codes mRNA and proteins. mRNA binds to tRNA and enzymes in ribosomes to form peptides from the amino acids.
Where in the cell are cell enzymes located?
Enzymes are formed the same way other proteins are formed - mRNA from the nucleus is transcribed by the ribosomes and the primary structure is formed. The ribosome guides the amino acid chain into folding into its secondary and tertiary structure; this is done partially in the rough endoplasmic reticulum and partially in the cytoplasm. Some cells also have lysosomes where the final activation of the enzyme takes place.
Are ribosomes active in carbohydrate synthesis?
No, ribosomes make protein from mRNA. Sugars and starches are made by smaller enzymes
How do viruses and cellular organisms differ?
Viruses are not classified as living, while cellular organisms are. Viruses are essentially a protein case with mRNA inside. Cells are far more complicated.
Where are enzymes located?
The enzyme is mainly found in the saliva and stomach. But it can also be found in the pancreas and duodenum. =)
What cellular organelle is responsible for receiving the mRNA and turning it into a protein?
Ribosome
What are molecules that catalyze chemical reactions?
Enzymes
A cellular process that is accomplished by a ribosomes?
Protein synthesis is a cellular process that is accomplished by ribosomes. Ribosomes are responsible for translating the genetic information encoded in mRNA into a specific sequence of amino acids, which form proteins. They do this by reading the mRNA and aligning the correct amino acids according to the codons on the mRNA strand.
What cellular process leads to the production milk-specific mRNA molecules?
Signal transduction

What are proteins synthesised?
Proteins are synthesized in cytoplasm. mRNA is transcribed in the nucleus by DNA which will be exported to cytoplasm. The mRNA together with the machinery such as ribosomes, tRNAs and enzymes synthesize proteins.
How is DNA translation controlled?
Translation of the mRNA code is controlled by enzymes. DNA is not directly translated into proteins.
Where within a cell are catalyst synthesized?
Enzymes are natural catalysts produced by cells, and all enzymes are proteins made in the cytoplasm of the cell by translation of genetic material (mRNA).
Are ribosomes active in carbohydrate synthesis?
No, ribosomes make protein from mRNA. Sugars and starches are made by smaller enzymes
