Answer:
The correct sequence of events in protein synthesis is transcription then translation. First, during transcription DNA is copied to mRNA in the nucleus. Then, mRNA is edited, processed and exported to the cytoplasm. Next, translation occurs.
Explanation:
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein. The process in which the messenger RNA (mRNA) molecule on a ribosome is decoded to produce a sequence of amino acids for protein synthesis. The process in which a strand of messenger RNA (mRNA) is synthesized by using the genetic information found on a strand DNA as a template.
The correct sequence of molecules involved in protein synthesis from beginning to end - DNA → mRNA → tRNA → Protein
Protein synthesis is a two-step process that involves transcription and translation to make proteins from a DNA sequence through the help of other molecules and organelles.
- Transcription is the process of copying genetic information from the DNA sequence into the mRNA sequence that moves to the cytoplasm.
- The translation starts in the cytoplasm that is a translation of mRNA molecules to amino acid chains.
- mRNA molecules bind to the ribosome and with the help of tRNA molecules form an amino acid sequence.
- These amino acids chain are called peptide chains or proteins.
Thus, the correct sequence of molecules involved in protein synthesis from beginning to end - DNA → mRNA → tRNA → Protein
