Stages of transcription: initiation, elongation termination (article . . . Before transcription can take place, the DNA double helix must unwind near the gene that is getting transcribed The region of opened-up DNA is called a transcription bubble Transcription uses one of the two exposed DNA strands as a template; this strand is called the template strand
Overview of transcription - Khan Academy In the following articles, we'll take a more in-depth look at RNA polymerase, the stages of transcription, and the process of RNA modification in eukaryotes We'll also consider some important differences between bacterial and eukaryotic transcription
Overview of translation (article) | Khan Academy Step 1: transcription! Here, the DNA sequence of a gene is "rewritten" in the form of RNA In eukaryotes like you and me, the RNA is processed (and often has a few bits snipped out of it) to make the final product, called a messenger RNA or mRNA Step 2: translation!
Intro to gene expression (central dogma) - Khan Academy Transcription: One strand of the gene's DNA is copied into RNA In eukaryotes, the RNA transcript must undergo additional processing steps in order to become a mature messenger RNA (mRNA)
Eukaryotic pre-mRNA processing | RNA splicing (article) - Khan Academy The steps we just talked about are pretty similar to what happens to RNA transcripts in the cells of your body In humans and other eukaryotes, a freshly made RNA transcript (hot off the RNA polymerase "presses") is not quite ready to go
Stages of translation (article) | Khan Academy Cells need translation to stay alive, and understanding how it works (so we can shut it down with antibiotics) can save us from bacterial infections Let's take a closer look at how translation happens, from the first step to the final product
RNA and protein synthesis review (article) | Khan Academy The first step in decoding genetic messages is transcription, during which a nucleotide sequence is copied from DNA to RNA The next step is to join amino acids together to form a protein
Eukaryotic gene transcription: Going from DNA to mRNA These mRNA transcripts escape the nucleus and travel to the ribosomes, where they deliver their protein assembly instructions The creation of mRNA transcripts (the creation of these portable genes) is called gene transcription Let’s learn about it
Transcription and mRNA processing (article) | Khan Academy Transcription consists of initiation, elongation, and termination The transcription of a gene into an mRNA molecule is divided into three phases: initiation, elongation, and termination
