DNA strand...Base sequence..?

Question

If the nucleotide or base sequence of the DNA strand used as a template for messenger RNA synthesis is ACGTT, then the sequence of bases in the corresponding mRNA would be??

Oh I really don't get this stuff...

Answer 1

UGCAA

Answer 2

Ok its really easy

In DNA there are four bases A, T, C AND G. they always are paired with bases which fit them;

A goes with T, C goes with G.

However mRNA (and tRNA) are slightly different in its structure and can not fit T's so they are replaced by U's (uracil)
The letters are in columns of the following order;
DNA strand 1, DNA strand 2, mRNA matching strand 1, tRNA
A T U A
T A A U
C G G C
G C C G

Your sequence is ACGTT (STRAND 1) so on the mRNA match it will be UGCAA

Hope this helps

Answer 3

Hey don't worry about it, all you have to remember is that the DNA strand & its COMPLIMENTARY strand will have COMPLIMENTARY sequence ie A paired with T & G with C etc. From the DNA strand to the RNA you MUST remember that you are going to put the complimentary base, but where there is a T you must put a U for the uracil. Your just need to practice these things & you will get the hang of it!

Answer 4

The answer is UGCAA. It can get crazy at first. If you have anymore question in Human Anatomy or Physiology hit me up
DNA mRNA

A=T A=U
G=C C=G

Answer 5

UGCAA

It goes A-T and G-C, except when you are making RNA the T is a U...that sounds confusing but if you practice enough it sinks in, just remember for DNA --> MRNA its A-U and G-C

Answer 6

A matches with T, or U in RNA
G matches with C
so take
DNA:
ACGTT
TGCAA

RNA:
ACGTT
UGCAA

DNA- deoxyribonucleic acid
A- adenine
T- thymine
U- uracil
G- guanine
C- cytosine
RNA- ribonucleic acid

Answer 7

mRNA will always have an opposite message to what the template is. In this case the template is ACGTT. You must remember though that RNA does not have T in it! RNA has U in place of T. Because of this, the mRNA would read UGCAA
