mRNA is a short term intermediate and once processing is complete mRNA dissolves. During processing mRNA becomes degraded as it reads the codons.

Transcription: the DNA sequence is transcribed into mRNA in the nucleus. mRNA Processing: the pre-mRNA is modified and processed into mature mRNA, which is then transported to the cytoplasm. Translation: the mRNA is translated into a specific amino acid sequence by ribosomes in the cytoplasm to synthesize a protein.
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.
An intervening sequence of DNA that is not expressed is called an intron. Intron sequences are removed during RNA processing, while the remaining expressed sequences are known as exons.
The processed mRNA sequence that is ready for translation is called mature mRNA. It has had introns removed and exons spliced together during post-transcriptional processing. This mature mRNA is then exported from the nucleus to the cytoplasm for translation into protein.

The process by which the expressed sequence of DNA codes for a protein is called protein synthesis. This process involves two main steps: transcription, where the DNA sequence is copied into a messenger RNA (mRNA) molecule, and translation, where the mRNA is used as a template to assemble amino acids into a protein.
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.
An intervening sequence of DNA that is not expressed is called an intron. Intron sequences are removed during RNA processing, while the remaining expressed sequences are known as exons.
The correct sequence of events for a mutation to affect the traits expressed by a cell is as follows: first, the mutation changes the DNA sequence of a gene. Next, this altered DNA is transcribed into messenger RNA (mRNA). Then, the mRNA is translated into a protein. Finally, the change in the protein can lead to a modified phenotype or trait expressed by the cell.
No, mRNA does not contain thymine in its nucleotide sequence. Instead, mRNA contains uracil in place of thymine.
There are three possible reading frames for a sequence of mRNA.
mRNA contains uracil in its nucleotide sequence, not thymine.
