introns
The correct sequence of events for a mutation to affect the traits expressed by a cell is as follows: first, the mutation changes the DNA sequence of a gene. Next, this altered DNA is transcribed into messenger RNA (mRNA). Then, the mRNA is translated into a protein. Finally, the change in the protein can lead to a modified phenotype or trait expressed by the cell.
After processing, the mRNA sequence consists of exons, which are the expressed regions that code for proteins, joined together after the removal of introns. This mature mRNA is then translated into a protein by ribosomes in the cytoplasm.
mRNA
mRNA is translated into proteins by the ribosomes in the cell. This process involves decoding the mRNA sequence into a specific amino acid sequence which ultimately determines the protein's structure and function within the cell.
The process by which the expressed sequence of DNA codes for a protein is called protein synthesis. This process involves two main steps: transcription, where the DNA sequence is copied into a messenger RNA (mRNA) molecule, and translation, where the mRNA is used as a template to assemble amino acids into a protein.
introns
The processed mRNA sequence that is ready for translation is called mature mRNA. It has had introns removed and exons spliced together during post-transcriptional processing. This mature mRNA is then exported from the nucleus to the cytoplasm for translation into protein.
The sequence of amino acids in a protein is directly determined by the sequence of nucleotides in the gene that codes for that protein. This process occurs during protein synthesis, where the genetic information is transcribed from DNA to mRNA and then translated into a specific sequence of amino acids.

The specific expressed sequence of DNA that codes for a protein in this genetic sequence is called a gene.
The sequence of amino acids in a protein is determined by the sequence of nucleotides in the mRNA, and this is determined by the sequence of nucleotide bases in the DNA.
The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene that codes for that protein. This gene is transcribed into messenger RNA (mRNA) which is then translated into a specific sequence of amino acids based on the genetic code. Each set of three nucleotides (codon) in the mRNA specifies a particular amino acid to be added to the growing protein chain.
The portion of the protein molecule that is coded for by mRNA is the sequence of amino acids. Each set of three nucleotides in the mRNA, called a codon, corresponds to a specific amino acid in the protein sequence. This process of translating mRNA into a protein is carried out by ribosomes during protein synthesis.
