1) I understand the DNA/RNA assembly process - I don't understand the phrase, "RNA composes of ATP besides others". (I read that as RNA is composed of ATP and other molecules) 2) Meh. 3) My definition of perfect sequence includes room for variability. If medicine wasn't at the state that i...

1) I'm not sure what this means.

2) Do you have any links?

3) DNA does have to be strung together in a perfect sequence to create a cell that functions correctly. And my textbook says that had to happen for millions of generations for evolution to work. Am I missing something?

I don't think ATP is RNA, though it is based on adenine. I don't know the chemistry as well as I should but I think it's adenine + ribose + some phosphorus bonds. I think I understand the basic theory - it's the billions of years and huge numbers part that is giving me heartburn. Nucleotides have to...

I'm thinking about how to get to cells from nothing. I've discovered recently that without helicase, ribosomes and ATP, and several other components, cells cannot function. Evolution is supposed to explain the gap between starting with nothing and fully functioning cells. Therefore, what was before ...

A cell cannot go on as it is without ATP.

Thanks for the info. I should have realized that prokaryotes would have a different mechanism. After reading further on ATP itself, I'm still stuck at the same point. The RNA world theory would have to include a way for evolution to create both ATP as an energy currency and the mechanisms to create ...

I didn't realize that there were other biological sources for ATP. Please explain that further, if you don't mind. I'm most interested in how they would have been involved in the evolution of RNA to the fully functioning DNA model. How/where would they have been used as RNA was evolving? I'm still a...

Re: Do the simplest bacteria have ribosomes and helicase?

Thanks for the information. I've done some research and I'm still having a hard time making the connection. Discounting the fact that DNA as a code base (logical) is structured information, and therefore cannot self-assemble, nucleotides, which are the "bits" that make up the code (physica...

So if life sprang out of nothing, which came first? The helicase or the ribosome? I assume the code for creating both of these machines comes from DNA which needs both helicase and ribosomes to function...

Do the simplest bacteria have ribosomes and helicase?

I find it interesting that all life on earth, aside from RNA viruses, use DNA. I've seen video on how helicase and ribosomes work together to copy DNA sequences (to RNA) with helicase then recreate them using ribosomes. Does this process work the same way in the simplest life forms? Bacteria and oth...
