Question

The pictured structure codes for how many amino acids?



12
4
6
2

Answer 1

have you heard of triplet code?

Answer 2

Yes I have.

Answer 3

alright so what does it state?

Answer 4

Three nucleotides are coded for one amino acid, right?

Answer 5

correct

Answer 6

Cause then RNA would be able to code for 64 amino acids. Which is can cover the 20 we meed.

Answer 7

to be precise its 3 nitrogenous bases that are the 'code'

Answer 8

Oh gosh I can't spell. XD *Cause then the RNA would be able to code for 64 amino acids. Which is enough to cover all the ones we need. And yes, it's three bases that are the code.

Answer 9

we have 20 amino acids in total
each amino acid can have multiple sets of codes (2-4)
so in total we have 64 sets of combinations for 20 amino acids

Answer 10

so now, how many possible amino acids do you see in that picture?

Answer 11

Considering that we're talking about amino acids, will I have to convert T to U? @Somy

Answer 12

and then I have to find the amino acids it codes for?

Answer 13

you can
but not to waste time, you can just think of triplet rule

Answer 14

So three equals one? Wouldn't that be four amino acids?

Answer 15

oh btw the codon table that u can find on google shows the triplet codes on mRNA so be careful
DNA to mRNA is also complimentary + T is replaced by U as you said

Answer 16

thats correct

Answer 17

Thanks so much! I thought it was four, but then someone said two and I got confused. But thanks again!

Answer 18

just to clarify, id DNA as in your case, is TAC, then mRNA of it will be AUC, usually it would be T, but in case of RNA its always U

Answer 19

no problem :)
i was a little confused too but mind you, these two can be complimentary but when we do mRNA transcription we use single strand
so you gotta get 2 from one strand and 2 from the other

Answer 20

Ahhhh, I understand that now!

Answer 21
