"Protein synthesis begins with a process called translation which occurs in the ribosomes, located in the endoplasmic reticulum. mRNA copies genetic information from the nucleus in a process called tr ...
"Because DNA is unique to an individual, we can use DNA fingerprinting to match genetic information with the person it came from. First, we use the polymerase chain reaction (PCR) technique to copy a ...

"Translation is the process in biology in which a ribosome uses the information stored in messenger RNA (mRNA) link together the sequence of amino acids which form proteins. Translation is preceded by ...
"Transcription is the process in biology in which a cell forms messenger RNA (mRNA) to guide protein synthesis, also known as translation. The mRNA copies a single gene from the DNA in the form of a s ...
