What is next after this sequence of DNA?

Question

aat tgc gga tcg act

Please help urgently

Answer 1

x genetics and chromasones

Answer 2

tta acg cct agc tga

Answer 3

Remember,in DNA adenine always pairs with thiamine and cysteine with guanine.

Answer is- tta acg cct agc tga

Answer 4

a ( adenin) is attached to t (thymin)

g (guanin) is attached to c (cytosin)

so aat tgc gga tcg act

      tta acg cct agc tga

forming the double helice of DNA containing genes

Answer 5

This is an impossible question to answer without more information. By asking what is next, you're implying that we should be able to predict the next few nucleotides on this strand of DNA, but that's impossible. If this is the end of a coding region, a stop codon would be either TGA, TAG, or TAA.

Almost everyone else tried to answer with the complementary DNA strand, but still got it wrong. They all picked the appropriate base pairs, but forgot that DNA strands are antiparallel, meaning one strand runs in one direction and the complementary strand runs in the opposite direction. However, the convention is that all sequences are read from the 5' to 3' direction.

If you want the complementary strand of DNA (or the messenger RNA), take a look at strand (2):

1)   5'- AAT TGC GGA TCG ACT -3'

2)   3'- TTA ACG CCT AGC TGA -5'

but read it in the 5'-to-3' direction. Rewritten, it is:

5'- AGT CGA TCC GCA ATT -3'

The mRNA would be:

5'- AGU CGA UCC GCA AUU -3'

Do you have any more information? I'd be happy to answer it if you do...

Answer 6

also remember that if it is coding onto RNA the a will become a u because RNA doesn't have thymine as a base, it has uracil
