Translation

In which direction do the ribosomes read mRNA?

3' 5'
or
5' 3'

I am thinking the first one... but can't find in my notes where it says it...

[jiranab]

in transcription it goes from 5' to 3'
but would it be the same for translation i'm not sure

ok.. so now i have confused myself.. another text says replication is from the 3' to the 5'... so i'm sorry..

It goes from 5' to 3'.

Thanks Guys. It makes sense that it is from 5' 3' now, since it came up in a question I was doing...

So, just to confirm, is this right:
- mRNA is produced from 5' 3', where the DNA is read from 3' 5'
- mRNA is read at the ribosomes from 5' 3'

Thanks again, in advance.

awww... you were trying to help me, and you've confused yourself... *feels guilty*

I think you got confused, possibly because, in translation mRNA is not read, but it is produced, hence the directions will be different in both cases, due to this difference.

Correct me if I am wrong, anyone, please!

EDIT: just re-thought it, it is actually: when mRNA is produced and read, it is in the same direction: 5' 3'. my bad. :uglystupid2:

yep read from 3-5, mrna is produced 5-3 (remember the nucleotides have to be added on the hydroxyl group which is on the 3' end)

so read 5-3 down the mrna strand in triplets

Beautiful! Thank you soo much!!
