Hey, everyone. So in this video, we're going to take an overview of Protein Synthesis. Here, we're going to see if the information to synthesize proteins is encoded within DNA. And we're going to say that the central dogma is that the flow of genetic information is from DNA to proteins via or through RNA. Now, here we have two ideas, transcription and translation. In transcription, we're going to say, it's the process that's going to build mRNA using DNA as the coding template. So in this image here, we have our double helix which represents DNA. Through transcription, we're able to copy a portion of DNA to create mRNA. From there, we go to translation, which is 2. And in translation, this is the process that builds proteins using the information carried by RNA specifically mRNA. So here, we're going from mRNA to protein. So, in layman's term, we can say that this is what we call the Central Dogma: we're going from DNA to mRNA to protein. And that happens by going first through transcription and then finally through translation. Now, here we're going to say transcription and translation themselves are collectively referred to as our gene expression. Remember, the genes that are encoded within our DNA are unlocked to help create mRNA so that eventually we can make the necessary amino acids and proteins necessary through translation. Alright. So just keep this in mind when we're talking about Central Dogma: it's just DNA to mRNA by way of transcription and then mRNA to protein by way of translation.

Here it says, which molecule acts as an intermediate in the process of information transfer from DNA to protein? Remember, the basis of the central dogma is that we're going from DNA to protein by going through mRNA. Remember, DNA to mRNA happens by transcription, mRNA to protein happens by translation. Here, our mRNA which is messenger RNA acts as our intermediate. So here our final answer would be option c.
