Can someone explain (simply) the main steps in Protein Synthesis, or link me to a good website?

And what substance are A, T, C, G?!
Thanks

I'll try and find a good website to explain it. But meanwhile, the bases in DNA are:

Adenine
Thymine
Cytosine
Guanine

In RNA:

Adenine
Uracil
Cytosine
Guanine

A T C and G are abbreviations of the nucleotide bases Adenine, Thymine, Cytosine and Guanine

Nucleotide Bases? i think

No worries!

I'm guessing the end of 1b says "are a part of?". So yes, that'd be DNA

This PDF may be of some help to you, as you're also doing Biology: https://www.bangor.ac.uk/ccm/documen...s-revision.pdf

(Pages 76-86 are to do with Protein synthesis )

Another level of detail; could say - Purine = Adenine,Guanine, Pyrimidine= Cytosine, Urasil, Thymine



Biology123ABC , what level are working at? GCSE? A-Level? I didn't need to know about purines/pyrimidines until Uni so I wouldn't worry if you've never heard of them.

We're learning about purines and pyrimidines at AS-Level :yes: (But that might be because we're doing new spec Biology)

They are Nitrogenous Bases, Adenine and Guanine are Purines and Cytosine and Thymine are pyrimidines
A pairs to T in DNA (Uracil replaces Thymine in RNA) and G pairs to C
they form hydrogen bonds between one another

As the names and meanings of the bases are explained, I just name the main steps as simply as I can and it is possible.

- transcription: an m-RNA is generated based on a DNA strand of complementary bases (A, T, C and G).

- translation: an m-RNA strand is formed after decoding in transcription. The information of DNA is translated to RNA completely.

- transfer: the m-RNA is transferred by a t-RNA to the ribosomes. At the ribosome, the m-RNA is bound to the r-RNA of the ribosome. This procedure is repeating by another transporting m-RNAs. Polypeptides are creating, a protein is synthesised, the t-RNAs are vanished (detach from m-RNA).
