During the process of translation, the code for genetic information changes from messenger RNA (mRNA) to a sequence of amino acids that form proteins. The ribosome reads the mRNA in sets of three nucleotides called codons, each of which corresponds to a specific amino acid. Transfer RNA (tRNA) molecules then bring the appropriate amino acids to the ribosome, facilitating the assembly of the protein chain based on the mRNA template. This process transforms the genetic code into functional proteins that carry out various roles in the cell.
Factors that may lead to changes in a cell's genetic information include mutation-causing agents like radiation or chemicals, errors during DNA replication, environmental factors like UV radiation, and viral infections that integrate their genetic material into the host cell's genome.
The molecule responsible for carrying genetic information from the nucleus to the ribosomes is messenger RNA (mRNA). It is transcribed from DNA and serves as a template for protein synthesis during translation. mRNA transports the genetic code from the DNA in the nucleus to the ribosomes in the cytoplasm, where proteins are synthesized.

The term that refers to a new trait resulting from changes in genetic information is "mutation." Mutations can occur due to various factors, including errors during DNA replication, exposure to radiation, or chemical influences. These genetic alterations can lead to new characteristics in an organism, which may affect its survival and reproduction.
mRNA decodes information from DNA during protein synthesis, which occurs in the ribosomes. The mRNA carries the genetic code from the DNA to the ribosomes where it is used to assemble amino acids into proteins following the rules of the genetic code.
The piece of genetic information removed from an mRNA strand after translation is called the poly-A tail. It is a stretch of adenosine nucleotides added to the mRNA during post-transcriptional processing.
mRNA molecules are involved in transcription but not translation. mRNA carries the genetic information from DNA to the ribosome for protein synthesis during translation.
The 5' prime end of DNA is significant in genetic processes because it is where the genetic information is read and copied during processes like transcription and translation. This end serves as the starting point for these processes, determining the direction in which genetic information is read and synthesized.

Transcription and translation are key processes in gene expression that convert genetic information from one form to another. During transcription, the DNA sequence of a gene is copied into messenger RNA (mRNA), transforming the information from a stable DNA format into a more mobile RNA format. Subsequently, during translation, the mRNA is read by ribosomes to synthesize proteins, converting the nucleotide sequence into an amino acid sequence, which ultimately determines the protein's structure and function. This process exemplifies the flow of genetic information from DNA to functional proteins.
Multiple codons code for the same amino acid in the genetic code to provide redundancy and reduce the impact of errors during protein synthesis. This redundancy helps to ensure accurate translation of the genetic information into proteins.
During transcription, the genetic information is rewritten as a molecule of
The process of converting information in mRNA into amino acids is called translation. During translation, the ribosome reads the sequence of nucleotides in the mRNA and uses this information to assemble a chain of amino acids according to the genetic code. Transfer RNA molecules bring the corresponding amino acids to the ribosome, where they are linked together to form a protein.
