Best Answer

Never - Uracil is only found in RNA. The four bases of DNA are A, T, G and C. In RNA, U replaces T.

Is aggcguc a sequence of DNA?

No DNA sequence wont have U (uracil), so it is an RNA sequence!


What is the complementary mRNA sequence to the DNA sequence A-A-T-G-G-C?

The complimentary mRNA sequence would be: U-A-A-C-G-U


What is the complementary sequence for this DNA c-t-a-a-g-t-c?

To find the complementary sequence for a given DNA sequence, you need to match each nucleotide with its complementary base according to the base-pairing rules. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Given the DNA sequence: C - T - A - A - G - T - C The complementary sequence would be: G - A - T - T - C - A - G


If the base sequence of the DNA is gtcaggatc what would be the corresponding base sequence of the messenger rna?

Wrong. UAC is the complimentary base sequence on the mRNA strand. RNA does not use the T nucleotide don u think if it should be written like CAU coz rna polymerase reads 3 to 5 and gives 5 to 3


Why is it possible to use a DNA sequence to identify bacteria?

Just as each human has their own unique DNA, each strain of bacteria shares their own DNA sequence.


What is the change in DNA sequence that affects genetic information?

Mutation


If the sequence of bases in a nucleic acid were AUCGA is it a strand of DNA?

No, because "U," or Uracil, is found in RNA and not DNA.


During DNA replication which sequence of nucleotides will bond to the sequence ACGTAT?

The RNA base sequence will be CGAUUAGGCThis answer assumes that the DNA sequence in the question is the sequence on the template strand.The way to work it out is to take the complementary base of each base in the DNA:the complement of G is Cthe complement of C is Gthe complement of A is U in RNA (T in DNA)the complement of T is AAnswer is actually (E) ATACA because if you use TATGA and do the complement, which is a=t and c=g


What would be the base sequence of the complementary mRNA strand?

TGCA


What is the code that real DNA use to store information?

The DNA code is carried in the sequence of nitrogen bases.


A section of DNA has the base sequence GCTTAA the corresponding messanger RNA base sequence will be?

RNA is copied just like DNA, except thymine (T) is replaced by uracil (U), so the corresponding base sequence for GCTTAA would be CGAAUU
