It's not a strand that is replaced, but a nitrogen base, much like adenine. The pyrimidine thymine is replaced by another pyrimidine uracil.
Uracil pairs with adenine in mRNA and replaces thymine in the DNA strand during transcription.
To determine the base sequence of a DNA strand from a given mRNA sequence, you need to consider that mRNA is synthesized from the DNA template strand through a process called transcription. The mRNA bases pair with their complementary DNA bases, where adenine (A) pairs with thymine (T), uracil (U) in mRNA pairs with adenine (A) in DNA, cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C). Therefore, to find the DNA base sequence, you can convert the mRNA sequence to its corresponding DNA sequence by replacing U with A and reversing the order to get the complementary DNA strand.
During the formation of messenger RNA (mRNA), adenine pairs with uracil in RNA. This occurs during transcription, where RNA polymerase synthesizes the mRNA strand by using the DNA template. The adenine nucleotide from the DNA template binds to uracil in the growing mRNA strand, replacing the thymine found in DNA.
No. Messenger RNA forms a complementary strand in which each DNA base is paired with its complementary base in mRNA. For example, if the DNA sequence is AGCTTG, the mRNA sequence will be UCGAAC. Notice that U for uracil in RNA pairs with adenine in DNA. This is because uracil takes the place of thymine in RNA.
It will use adenine, but thymine will be replaced by a nitrogen base called "uracil" in mRNA
The nucleotide sequence of the mRNA strand is determined by the template DNA strand during transcription. It is complementary to the DNA template and consists of adenine (A), uracil (U), cytosine (C), and guanine (G). For example, if the DNA template strand is 3'-ATCGTACG-5', the corresponding mRNA sequence would be 5'-UAGCAUGC-3'.
Yes, the mRNA strand complementary to the DNA sequence AATTGC would be UUAACG. This is due to the selective base pairing rules between adenine (A) and uracil (U), thymine (T) and adenine (A), guanine (G) and cytosine (C).
During transcription, the mRNA strand is synthesized complementary to the DNA template strand. For the DNA strand GCA TTA, the corresponding mRNA would be CGU AAU. This is because adenine (A) pairs with uracil (U) in RNA, while cytosine (C) pairs with guanine (G) and vice versa.
In transcription, the mRNA strand is formed by complementary base pairing of the template DNA strand. However we should note that the nitrogenous bases in mRNA are Adenine, Guanine, Cytosine and Uracil, while those in DNA are Adenine, Guanine, Cytosine and Thymine.So the mRNA strand would be formed by matching the A in DNA with U in mRNA, T in DNA with A in mRNA, C in DNA with G in mRNA and G in DNA with C in mRNA.I hope that helps!
To find the mRNA base sequence, you first need to identify the corresponding DNA template strand. The mRNA is synthesized by RNA polymerase during transcription, where it complements the DNA template. In this process, adenine (A) in DNA pairs with uracil (U) in mRNA, while thymine (T) pairs with adenine (A), cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C). The resulting mRNA sequence is a copy of the coding DNA strand, substituting uracil for thymine.

First of all, it is codons,not condons. MRNA would have uug auc cca. If I am not incorrect, you only use the term codons for MRNA, not in the actual DNA strand. The Anticodons would then be in the TRNA, which codes for the Amino Acids needed by the cells.
