What is transcription?
Transcription is the process of making RNA from a DNA template. Several key factors are involved in this process. Including, DNA, transcription factors, RNA polymerase, and ATP. Transcription begins with a strand of DNA. It is divided into several important regions. The largest of these is the transcription unit. This portion of the DNA will be used to produce RNA. Upstream of the transcription unit is the TATA box. An enhancer region may also be involved. Several complexes, known as transcription factors, are required for successful transcription. The first is TFIID, the largest of the general factors. A component of this factor, TBP, binds to the DNA using the TATA box to position TFIID near the transcription initiation site. Other transcription factors, including TFIIA and TFIIB, then attach. These complexes prepare the DNA for the successful binding of RNA polymerase. One RNA polymerase is bound, other transcription factors complete the mature transcription complex. Now, energy must be added to the system for transcription to begin. This energy is provided by the reduction of ATP into ADP and Pi. RNA polymerase then synthesizes an RNA template from the strand of DNA. Most factors are released after transcription begins. When the end of the transcription unit is reached, the RNA polymerase dissociates, and the newly formed strand of RNA is released.
What is Translation?
Translation is the synthesis of a protein from an mRNA template. This process involves several key molecules including mRNA, the small and large subunits of the ribosome, tRNA, and finally, the release factor. The process is broken into three stages: initiation, elongation, and termination. Eukaryotic mRNA, the substrate for translation, has a unique 3'-end called the poly-A tail. mRNA also contains codons that will encode specific amino acids. A methylated cap is found at the 5'-end. Translation initiation begins when the small subunit of the ribosome attaches to the cap and moves to the translation initiation site. tRNA is another key molecule. It contains an anticodon that is complementary to the mRNA codon to which it binds. The first codon is typically AUG. Attached to the end of tRNA is the corresponding amino acid. Methionine corresponds to the AUG codon. The large subunit now binds to create the peptidyl (or P) site and the aminoacyl (or A) site. The first tRNA occupies the P-site. The second tRNA enters the A-site and is complementary to the second codon. The methionine is transferred to the A-site amino acid, the first tRNA exits, the ribosome moves along the mRNA, and the next tRNA enters. These are the basic steps of elongation. As elongation continues, the growing peptide is continually transferred to the A-site tRNA, the ribosome moves along the mRNA, and new tRNAs enter. When a stop codon is encountered in the A-site, a release factor enters the A-site and translation is terminated. When termination is reached, the ribosome dissociates, and the newly formed protein is released.

my genetics professor showed us this in the first lecture watching this again helped a lot in the finals
Don't know all of the terms used but the visual made it very clear for me how it works. Thank you
this video is so useful, it really helps semester 1 medical student
Thank you so much.I was way confused in this topic ,but in seconds you cleared all my doubts.Thank you so much.
LOVE IT!!! Thank you so much!!!
thank you, great vid
thoroughly understood. it's help me much more for my exam.
came looking for 12th grade level stuff and just blown off my mind...
a good lecture to see in short time
So Good. Thanks....
nice,thanks .easy to understand
this video is very nice to learn such a complex concept
subscribed!!!😍..thank you very much
thank you.
The animations are super.
This video helps a lot, thankss
Thank you thank you thank you 😊
Thank you
Thanks 👍
excellent .
Excellent tq tq tq somuch
good video thanx
thanx
Very well teaching 🎼🎼 😘😘😘😚😆
Hocamlar bu kadar güzel açıklayamıyor işte..
very good video
Vayyy bee😂
Колко са многобройни делата Ти, Господи! Всичко си направил премъдро; (Пс 103:24)
nice vedio
q gran avance ha hecho la ciencia
THANK YOU!
There's a mistake in the video. There are 3 types of RNApolymerase. The most important is RNApol II which is the one that transcribes the mRNA. As we see in the video Rnapol II attaches to TATA box but then leaves the DNA magically, there's no terminal regions for this RNApol so it's not an accurate animation of that step. BTW nice video
What happen to the dna after it is transcribed does it get used again ?
good
…emm Is there a good video exlaining Okasaki fragments?Like Leading and Lagging strands stuff…I really don't get it.thanks🙏🙏🙏

Good. But what is function of formed protein, how we will find.

Formed protein used in the process for which it is being made .. for example it may use in any process of digestion
Plz... Give complete explanation...
got hungry looking at those sausage links
SIMPLE AF
Good afternoon mam Ritu yadav
you didnt even name the last 2 transcripiton factors -.-
you didn't mention pre mRNA
Transcription in hindi
This is good but too advanced

dont think it can be done any easier, maaaybee the thing with transcription factors tho, but its great video overall
This totally just came about by undirected material process. There is no way this is highly specific in design and function. Lol
