Transcription and Translation – Protein Synthesis From DNA – Biology

Transcription and Translation - Protein Synthesis From DNA - Biology



This biology video tutorial provides a basic introduction into transcription and translation which explains protein synthesis starting from DNA. Transcription is the process where DNA is used to create mRNA. RNA polymerase constructs DNA using the template strand or antisense strand. The other strand is called the noncoding strand or nontemplate strand. pre-mRNA is actually created first through 3 processes – initiation, elongation, and termination. After which, pre-mRNA undergoes RNA splicing where the introns are removed and the exons remain. mRNA now leaves the nucleus and enters the cytosol where it finds a ribosome which is the site where proteins are made. The nucleotide sequence found in mRNA is broken into sets of 3 forming codons which matches the anticodons found in tRNA. The transfer RNA molecule brings the amino acids needed to make the growing polypeptide chain forming a protein. The ribosome has three sites – The E site or exit site, the P site or peptidyl site, and the A site or amino acyl site where most tRNA molecules enter.

Man your explanation is so accurate, basically you're better than my teacher. Modular study really sucks.

I have a question. What happens to the original DNA strands that a segment was replicated from? Does it replicate? Does it get the complimentary bases? What really happens to it?

Thank you so much! It’s a shame that during COVID online learning, some professors don’t give lectures and basically tell you to figure it out yourself. This helped my understanding of this process a lot!

What is the name for the bond of aa,is a peptid bond ?I am a little bit confused about this bond because my teacher says that ia called enzyme ribosomal?

I feel you bro….but the intiation, elongation and termination things ain't for transcription…..these proccess are meant for translation…

I‘m a junior in college majoring in biochemistry. These vids are still very relevant. Thank you so much. There is such a volume of information, it helps to be able to watch someone explain the big picture in such an eloquent way.
