how do u make this into a complementary DNA strand and then into a messenger RNA strand?

Question

GTG CAC CTG ACT CCT GAG GAG

ok.....3 diff answers! whos correct? aww now im confused

Answer 1

original: GTG CAC CTG ACT CCT GAG GAG
complementary: CAC GTG TGA GGA CTC CTC

i'm not sure which strand you want the mRNA to be copied from, so if it's from the original,

original: GTG CAC CTG ACT CCT GAG GAG
mRNA: CAC GUG UGA GGA CUC CUC

but if it's copied from the complementary strand,

complementary: CAC GTG TGA GGA CTC CTC
mRNA: GUG CAC CUG ACU CCU GAG GAG

hope this helps..! =]

Answer 2

A binds to T and G to C in DNA

so the complementary DNA strand is

CAC GTG GAC TGA GGA CTC CTC

then in RNA, A binds to U, theres no T in RNA, so turn the above strand into an RNA strand by just using their compliments

GUG CAC CUG ACU CCU GAG GAG

--edit after two other posts--
the question asked turn it into a Complementary DNA strand, then use that complementary DNA strand to make a mRNA strand

therefore,i believe i have the right answer,
since one answer went directly from the DNA strand into the mRNA strand, which isn't what the question asked for

also, it is not stated whether which is the 5' end and which is the 3' end, and for a simple homework problem like this, i don't think the teacher would want to confuse the student more with that.

Answer 3

The complementary DNA strand is just the other side of the DNA molecule. It matches the strand given in the problem.

G matches C (round letters together)
A matches T (letters made of straight lines together)

Original: GTG CAC CTG ACT CCT GAG GAG
Comple: CAC GTG GAC TGA GGA CTC CTC

When messenger RNA is formed, the matching nucleotides are the same, except that an A on DNA matches a U on mRNA. (AU like AUstralia).

Original: GTG CAC CTG ACT CCT GAG GAG
mRNA: CAC GUG GAC UGA GGA CUC CUC

Answer 4

A is complemented to T (in DNA) or U (in RNA)
and C is complemented to G

So, 5' GTG CAC CTG ACT CCT GAG GAG 3' will be complemented with
3' CAC GTG GAC TGA GGA CTC CTC 5' or 5' CTC CTC AGG AGT CAG GTG CAC 3' (DNA strand)

RNA polymerase build mRNA from 5' to 3', Therefore it has to start with 3' end of template DNA

So, you will get mRNA 5' CUC CUC AGG AGU CAG GUG CAC 3'

Answer 5

Salam! wish this helps :) a million. The complementary base pairs are adenine and thymine, cytosine and guanine 2. the 1st step would desire to be the separation of the two strands, via DNA helicase. Then, DNA polymerase synthesizes the complementary strand 3. to chop up the two complementary DNA strands via breaking the hydrogen bonds between the complementary base pairs 4. It enables to synthesize the recent strand 5. TCCGAT 6. they are comparable 7. Sorry, I forgot the errors fee :( 8. they are mRNA (messenger RNA), tRNA (transpfer RNA) and rRNA (ribosomal RNA) 9. i'm uncertain what you're bearing on... 10. that's a particular sequence the place RNA polymerase will connect with start up transcription. that's on the beginning up of a gene. It additionally determines which of the DNA strands will act as a template for transcription. 11. i'm uncertain approximately this... 12. Sorry, dunno this the two... 13. RNA complementary nucleotides 14. Adenine with uracil, thymine with adenine, cytosine with guanine and guanine with cytosine 15. i'm guessing that's the codon that codes for the final amino acid sixteen. I dunno 17. tRNA 18. tRNA, and mRNA 19. uncertain... 20. Peptide bonds Sorry i don't be attentive to all of the solutions. wish I helped. and would Allah bless you and handbook you for the period of your attempt :)

Answer 6

Icie is correct. mRNA has to come from the complementary DNA strand.
