Transcription (making mRNA from DNA)

Process of Transcription

-The enzyme RNA polymerase binds to the DNA molecule and causes it to unwind. -The RNA polymerase recruits complementary nucleotides to create a chain of RNA using the DNA as the template. -The new strand that is created is single stranded and codes for the same exact traits that the DNA codes for. -One change is that Thymine is no longer located in the chain, it is instead replaced by Uracil. -Another change is that the sugar group is a ribose, instead of a deoxyribose.

What is Transcription?

-This is a process in which mRNA is produced by using DNA as a template. -DNA, in eukaryotes, is located in the nucleus, but can not leave. -mRNA is a transcribed copy of DNA that is able to leave the nucleus and travel into the cytoplasm.

mRNA

-mRNA: Messenger RNA is a single, uncoiled strand that transmits information from DNA. It is the initial code used to make a protein during protein synthesis. -It serves as a template for the assembly of amino acids during protein synthesis.
