Question

Where must an mRNA attach before protein production can begin?

Answer 1

Answer:

to a Ribosome

Explanation:

mRNA is produced inside the nucleus of a cell according to the genetic information present in the DNA of the cell. this process is known as Transcription.

Then it's sent to ribosomal subunits in the cytosol through nucleopores. then it attaches to the ribosome. the ribosome reads the nitrogenous base sequence and pairs the tRNAs with complementary nitrogenous bases. (your answer is here, but if you want to know more, continue reading it.)

Each tRNA contains a tri-nucleotide that is collectively known as an anticodon which has the complementary bases of the relevant codon on the mRNA.

Each tRNA has captured a protein. the type of protein is determined by the sequence of the anticodon.

It means two tRNAs with two different anticodons cannot bring the same protein to the ribosome.

the Ribosome separates the proteins attached to tRNAs and links them as a chain.

the final result is a polypeptide chain. I explained to you the basic protein synthetic process.
