anticodon on tRNA

[license2kill]

Members do not see this ad.

If the anticodon on tRNA complements the sequence on mRNA, wouldn't the anticodon be of the same sequence of the original template strand of DNA since the mRNA also complements the template strand? Is this correct?

Also, what is the difference from saying the "template strand of DNA" vs. the "sense" strand, are they virtually the same thing?

yes except that the tRNA has U's and the DNA has T's. for example, if the mRNA reads 5' AUG 3', the tRNA should read 3' UAC 5' and the DNA should read 3' TAC 5'. i dont no about the "sense" strand.

The Template strand of the DNA is the antisense strand. This is the strand that does not code for the product. It is used to serve as a template fro the DNA synthesis. Sense strand is the strand whose sequence is almost the same as the sequence of the mRNA,the difference is of course that RNA has Uracil and mRNA does not have introns.
Hope this helps.

Template strand = antisense strand
coding strand = sense strand

so "template strand of DNA" and the "sense" strand are the opposite

"template strand" is literally used as template to code "coding strand [or the strand that makes "sense" lol]" which has the genetic info for mRNA.

thanks for your help guys.

and the DNA should read 3' TAC 5'.

Is that of sense or non-sense DNA strand?

 

[license2kill]

the DNA would be the template thus the antisense strand according to this discuss, right?

sense. the nonsense would be 5' ATG 3'. some1 please correct me if im wrong.

3' to 5' strand of the DNA codes for the mRNA (since the transcription goes from 5' to 3'). So the strand that codes for mRNA is the coding strand (or sense strand) ofcourse.

So since 3' TAC 5' was the strand that coded mRNA, it is the sense or coding strand.

Dleodyddlek,

You put that very well.

I always like to remind myself that the process going on is protein synthesis. I pass on this tip because, of course, when the process is DNA replication BOTH strands of DNA serve are templates (called, as you all know, semi-conservative replication). Just adding my two cents.

Oh, another way to think of the sense/anti-sense strands of DNA (and the resulting mRNA molecule) is to think of photography. Remember, before digital? The sense strand of DNA during protein synthesis is the "positive" image, the anti-sense strand is the "negative image". Now, the mRNA that is built will be a "positive" copy of the DNA code (only with U for T) -- just how it is, accept it -- so it has to come from the anti-sense strand of DNA. 🙂

Another way to remember that mRNA will be a "positive image" is that it gets read by, um, anti-codons. So that's a little reminder.

sorry!! let me correct this. Coding strand (sense) doesn't serve as the template, anti-sense does.

so 3' TAC 5' is the anti-sense
