Question

Can someone please help me with this biology assignment. I cant figure out how to write it. The assignment is this:
For this assignment, you will write an essay describing the production of protein molecules through transcription and translation. Your essay should include discussions of the following:

■DNA
■mRNA
■RNA polymerase
■base pairing
■transcription
■translation
■tRNA
■rRNA
■ribosomes
■amino acids
■protein

Answer 1

This should probably be in the biology section, but I'll help out.

DNA is the information template that cells use to start creating proteins. Information only moves from DNA to RNA to Proteins (except for those darn retroviruses, but thats a total other topic) which forms the Central dogma of molecular biology.

To start, a certain region of DNA to be turned into a protein is copied into mRNA. This process is called transcription and occurs in the nucleus. What facilitates this copying is an enzyme called RNA polymerase. Which matches each base pair in the DNA strand to its respective base pair in the RNA strand.

Still working on the other parts, and I definitely haven;t covered everything, but this should be a nice general summary.

Answer 2

Thanks and I dont know how to put it in the biology section.

Answer 3

After transcription into mRNA, the mRNA goes through post transcriptional modification. Seeing as how thats not on your list I won't go into too much depth about it, but basically know that this step allows many different proteins to be formed from the same DNA template. Afterwards, the mRNA moves to ribosomes (made from rRNA) in either the cytoplasm or the rough endoplasmic reticulum, depending on the final destination of the protein (inside or outside the cell).

mRNA binds to the rRNA and now translation occurs. An amino acid chain forms when tRNA attaches to the respective base pairs on the mRNA molecule. This happens in units of threes, called codons. This process starts at a start codon (usually the amino acid methionine) and ends at a stop codon. After the translation process is done. The amino acid goes through post-translational modifications (not gonna go through it since its not on your list). The protein forms when secondary, tertiary and quaternary structures of the protein are made which mostly happens through intermolecular bonds.

This is a rough idea of the whole protein synthesis process, but I believe it should give you a general idea for your paper.

Thanks!!
