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

The letter "u" is used in DNA sequences to represent deoxyuridine, which is a base found in RNA but not in DNA. In RNA sequences, "u" stands for uracil instead of thymine, which is found in DNA sequences.

Is aggcguc a sequence of DNA?

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


DNA sequence acgtt will give what mRNA base sequence?

The mRNA base sequence corresponding to the DNA sequence acgtt is ugcaa. The mRNA sequence is complementary to the DNA sequence, with thymine (T) in DNA being replaced by uracil (U) in mRNA.


What sequence of mRNA would go with the DNA sequence of act?

The complementary mRNA sequence to the DNA sequence "act" would be "uga" after transcription, where thymine (T) in DNA is replaced by uracil (U) in RNA.


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


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

The corresponding messenger RNA sequence for the DNA sequence GCTTAA will be CGAAUU. This is because in RNA, adenine (A) pairs with uracil (U) instead of thymine (T) as in DNA.


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


How do you write the amino acid sequence for u-g-a-u-g-g-g-u-a-c-g-g-u-c?

The given sequence "U-G-A-U-G-G-G-U-A-C-G-G-U-C" represents the RNA sequence, not the amino acid sequence. To determine the corresponding amino acid sequence, you would need to perform translation by converting the RNA sequence into its complementary DNA sequence, then group the nucleotides into codons, and use the genetic code to find the corresponding amino acids.


If the DNA secquence to be transcribed is actg then the resulting mRNA sequence will be?

The mRNA sequence transcribed from the DNA sequence ACTG will be UGAC. In RNA, thymine (T) is replaced by uracil (U).


What is the sequence of the mRna produced from the strand of DNA a t a t g c g c t a a a?

The mRNA sequence transcribed from the DNA sequence "a t a t g c g c t a a a" would be "u a u a c g c g a u u u", where "u" represents uracil in RNA and is complementary to adenine in DNA.

What sequence in mRNA complements the sequence in the DNA template?

The sequence in mRNA is complementary to the DNA template, with thymine (T) in DNA being replaced by uracil (U) in mRNA. The complementary base pairing rules still apply: adenine (A) pairs with uracil (U), and guanine (G) pairs with cytosine (C).


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
