Oh, wow, oh, oh, wow, oh, wow, oh, man.

Oh, wow. Hello there. You're listening to The Science of Everything podcast, episode 35, DNA, structure, and function, part two.

So in this episode, we're going to continue directly from episode 34, so pretty good idea to listen to that first,

where I talked about the structure of DNA, including nucleotides, how they're connected together,

the different types of nitrogenous bases that are connected to the nucleotides,

well, a part of the nucleotides, and form the double-stranded structure of the DNA double helix.

We also talked about the genetic code, including the central dogma of molecular biology,

the one-gene-one-protein hypothesis, we talked about codons and the reading frame.

In this episode, what we're going to do is look at the details of how the central dogma works.

We're going to look at how we get from DNA to RNA and how we get from RNA to proteins.

Specifically, we're going to look at the processes of replication, transcription, and translation,

including how they start, or how they activated, how they

are continued, how they terminated, and how all that fits together and the structures that carry

these processes out. Let's get into it. We'll start with replication. So replication is actually

not exactly part of the central dogma because this is just about how DNA replicates itself,

or how we go from one DNA strand to two DNA strands,

contain essentially the same information. So DNA replication is the process by which a cell's

entire DNA is copied or replicated. This process occurs during the synthesis phase of the

eukaryotic cell cycle. So we haven't actually talked about the cell cycle before. That's a topic I

need to cover, actually. But there are different cell Cell cycles basically the cycle of life for cells, and there are different phases to that cycle.

One of them is called the synthesis phase, and it basically refers to the time when DNA is copying itself.

And that's important because if you're going to have a cell that divides up into two cells, you know, that replicates itself, obviously each of those
