Answer:
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy
Explanation:
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
hope this helps :)
can i have a brainilist pls
Answer:
Erect.
Explanation:
Paranasal sinuses are the group of air filled sacs that are present around the nasal cavity. Paranasal sinuses are present four in numbers. These are maxillary sinuses, frontal sinuses, ethmoidal sinuses and sphenoidal sinuses.
The radiography of paranasal sinuses using X ray technique is helful in medical diagnosing. The erect position provides the best image for the radiography of paranasal sinuses.
Thus, the correct answer is option (A).
It is the central vacuole
Answer:
Capping occurs at <u>5' end of the mRNA</u>.
Explanation:
Eukaryotic cell process the mRNA in nucleus before it moved to the cytoplasm for protein synthesis.
The RNA that is direct copy of DNA is called primary transcript.
The molecule that's directly made by transcription in one of your (eukaryotic) cells is called a pre-mRNA, reflecting that it needs to go through a few more steps to become an actual messenger RNA (mRNA). These are:
<u>Capping: </u>mRNA capping happens at the 5' end of the mRNA, usually adds metjyguanosine after RNA polymerase makes the 5' end of the primary transcript
<u>Polyadenylatio:</u>Addition of a poly-A tail (tail of A nucleotides) to the 3' end of the RNA
<u>Intron splicing:</u>Chopping out of introns, or "junk" sequences, and pasting together of the remaining, good sequences (exons)
Once it's completed these steps, the RNA is a mature mRNA. It can travel out of the nucleus and be used to make a protein.
