introns
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.
Proteins are synthesized in the cell by a process called protein synthesis. This process involves transcription of the DNA sequence into mRNA and translation of the mRNA into proteins by ribosomes. The sequence of nucleotides in the mRNA determines the sequence of amino acids in the protein, allowing for the correct protein structure and function.
The pattern for making proteins is determined by the sequence of nucleotides in DNA. During transcription, a segment of DNA is copied into messenger RNA (mRNA), which serves as the template for protein synthesis. The mRNA sequence is then translated into a specific sequence of amino acids, forming a protein. Thus, it is the mRNA that carries the copied genetic information from DNA to the ribosomes, where proteins are assembled.
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.

Polycistronic mRNA is a type of mRNA that contains the coding sequences for multiple proteins within a single transcript. This is common in prokaryotes and some viruses, where multiple genes are expressed from a single mRNA molecule. Each coding sequence in the polycistronic mRNA is typically followed by a ribosome binding site (RBS) to allow for efficient translation of each protein.

mRNA is usually targetted to ribosomes, which transcribe the sequence into a protein. Some mRNA molecules do not code for proteins but instead interract with DNA in the nucleus.
mRNA is translated into proteins during a process called protein synthesis. This process occurs in ribosomes, where the genetic information in mRNA is used to assemble amino acids into a specific sequence, forming a protein.
Transcription: the DNA sequence is transcribed into mRNA in the nucleus. mRNA Processing: the pre-mRNA is modified and processed into mature mRNA, which is then transported to the cytoplasm. Translation: the mRNA is translated into a specific amino acid sequence by ribosomes in the cytoplasm to synthesize a protein.
mRNA takes the genetic code to a ribosome, which is made of ribosomal RNA and proteins.
Translation is the process responsible for converting mRNA into proteins. During translation, ribosomes read the mRNA sequence and assemble the corresponding amino acids in the correct order to form a protein.
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
