Hey, everyone. So in this video, we're gonna 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 gonna say that the central dogma is that the flow of genetic information is from DNA to proteins via or through RN A. Now, here we have two ideas, transcription and translation in transcription. We're gonna say it's the process that's going to build MRN A 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 MRN A. From there we go to translation, which is two. And in translation, this is the process that builds proteins using the information carried by RN A specifically MRN A. So here we're going from MRN A to protein. So in layman's term, we can see that this is what we call the central dogma. We're going from DNA to MRN A to protein. And that happens by going first through transcription and then finally through translation. Now, here we're gonna say transcription and translations themselves are collectively referred to as our gene expression. Remember, the genes are encoded within our DNA are unlocked to help create MRN A so that eventually we can make the necessary amino acids and proteins necessary through translation, right? So just keep this in mind, we're talking about central dogma. It's just DNA to MRN A by way of transcription and then MRN A 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. So protein by going through MRN A, remember DNA to MRN A happens by transcription, MRN A to protein happens by translation. Here, our MRN A which is messenger RN A acts as our intermediate. So here our final answer would be option C.
