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.

What else can I help you with?
Can single mRNA be read more than once?
Idont know
Usually attached to rough endoplasmic reticulum and produce enzymes and other protein compounds?
These are ribosomes, small cellular organelles responsible for protein synthesis. They can be found attached to the rough endoplasmic reticulum, where they play a crucial role in translating mRNA into protein chains. This process helps produce enzymes and other protein compounds necessary for various cellular functions.
MRNA is eventually broken down by what enzyme?
mRNA is eventually broken down by ribonucleases, which are enzymes that catalyze the degradation of RNA molecules.
The 5' cap of mRNA is important for what?
The 5' cap of mRNA is important for several reasons: it protects the mRNA from degradation by exonucleases, helps in the recognition and binding of the mRNA by the ribosome for translation, and is essential for efficient splicing of introns.
Does DNA control the production of enzymes?
Yes, DNA contains the genetic information that codes for the production of enzymes. This information is transcribed into messenger RNA (mRNA), which is then translated into proteins, including enzymes, through a process called protein synthesis. Enzymes are essential for catalyzing biochemical reactions in the cell.

Where are the ribosomes that produce enzymes responsible for the first steps of sugar metabolism found?
The ribosomes responsible for producing enzymes involved in the first steps of sugar metabolism can be found in the cytoplasm of the cell. Ribosomes are the cellular structures where proteins are synthesized based on the instructions from messenger RNA (mRNA) molecules. These enzymes are essential for breaking down sugars and initiating the metabolic process.
Which organelle consists of a large number of RNA and enzymes?
Ribosomes. They are the location in which a large amount of RNA is synthesized and the synthesis of any cellular component needs a large amount of enzymes to speed up the process.
What happens to mRNA when it leaves a ribosome?
Once mRNA leaves a ribosome, it can be degraded by cellular enzymes or recycled for further rounds of translation. It may also undergo additional modifications, such as polyadenylation, to stabilize or target it for degradation. Ultimately, the fate of mRNA depends on various factors within the cell.
Does DNA control the production of enzymes?
Yes, DNA contains the genetic information that codes for the production of enzymes. This information is transcribed into messenger RNA (mRNA), which is then translated into proteins, including enzymes, through a process called protein synthesis. Enzymes are essential for catalyzing biochemical reactions in the cell.
How does the body know how to produce mRNA?
The body produces mRNA through a process called transcription, where an enzyme called RNA polymerase reads the DNA sequence and creates a complementary strand of mRNA. This process is tightly regulated by various cellular mechanisms to ensure the proper production of mRNA for different genes and cellular functions.
What is the function of the cap and tail on eukaryotic mRNA?
The cap and tail on eukaryotic mRNA play important roles in mRNA stability and translation. The 5' cap protects the mRNA from degradation and helps in the initiation of translation. The poly(A) tail at the 3' end of mRNA also plays a role in mRNA stability and regulation of translation.
Where does mRNA travele to in a cell?
mRNA is usually targetted to ribosomes, which transcribe the sequence into a protein. Some mRNA molecules do not code for proteins but instead interract with DNA in the nucleus.
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.
