Transcription is the process by which genetic information stored in DNA is copied into RNA molecules. This RNA can then serve as a template for protein synthesis during translation. Transcription is a critical step in gene expression and allows for the transfer of genetic information from the DNA to the cellular machinery that produces proteins.
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.
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.
A change in the genetic information code refers to a mutation or alteration in the DNA sequence that can result in a different protein being produced. This change can be caused by various factors such as errors during DNA replication, exposure to mutagens, or genetic recombination. An altered genetic code can lead to genetic disorders, changes in an organism's traits, or evolution over time.
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.

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.
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.
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.
During transcription, the genetic information is rewritten as a molecule of
RNA polymerase reads genetic information in the 3' to 5' direction during transcription.
