This may sound really stupid but I'll ask it anyway. In DNA replication when is it that the T (thymine) is replaced by the U??? Is it messenger or somewhere else?

u replaces t in the mRNA

Be careful to use the correct term.

DNA replication - DNA copies itself to make identical double helix

Transcription - DNA copied as single strand mRNA (here replace T with U)

Translation - mRNA translated to make polypeptide (3 bases ie codon = 1 amino acid)

Cheers

We actually got told that we don't need to know the terms transcription and translocation, they are not in the syllabus. Of course you need to know what happens in them, I find it easy anyway to remember them cos they you just fit the steps into them.

If your asked to model protein synthesis, and you want a band 6, you need to include those points.

True but if you use the term replication when talking about transcription you will lose marks, so my point is still ..... be careful
