The first (primary) transcript from a protein coding gene is often called a pre-mRNA and contains both introns and exons. Pre-mRNA requires splicing (removal) of introns to produce the final mRNA molecule containing only exons

∙ 11y agoThe premature mRNA is the transcribed product of the gene that codes specific protein but it still has some small sequences of nucleotides called introns. If those introns aren't removed the result will be shown on the translated gene. Even though a peptide may be produced it will not be the one coded by the gene. So premature mRNA goes through a process called RNA splicing in which snRNA combined with proteins removed the introns and put together the rest of the DNA sequences (exons) then the now mature RNA can exit the nucleus and travel in the ribosomes where it will be translated.

∙ 13y agopre-mrna has introns and exon as for mrna it removes the introns but remain exons

What mutation stops translation of the mRNA?
The type of mutation that stops the translation of a protein is a nonsense mutation. This occurs when a base substitution (point mutation) results in a STOP codon and thus stops translation of the sequence into a protein.
What is RNA processing?
1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added. 1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added.
What features of the mRNA make the mRNA last longer?
Viagra makes your penis last longer.
MRNA strand is made in the process of what?
mRNA is produced during the process of transcription, in which mRNA makes a complimentary copy of the DNA code.
What is the role of mRNA after it leaves the nucleus and enters the cytoplasm of a eukaryotic cell?
Transcription takes place in the nucleus. This process produces mature mRNA once the noncoding introns were removed. This mRNA then enters the cytoplasm to be translated. Translation occurs on the ribosome and it involves tRNA binding to the codon(on the mRNA). This process is known as protein synthesis
What needs to be removed from eukaryotic RNA to form mature mRNA?
RNA Polymerase
What makes up the final stage of mRNA?
Ribosomes translate mRNA into proteins.
What mutation stops translation of the mRNA?

Why are exons important?
Exons code for proteins. Exons are parts of DNA that are converted into mature messenger RNA.. From there, mRNA undergoes translation where mRNA is used to synthesize proteins.
What step in synthesis is transcription?
The excising of the introns from the mRNA and the adding of the poly A tail and guanine repeats to the mature mRNA so that it now exits the nucleus to begin translation.
What is the last step in transcription?
The excising of the introns from the mRNA and the adding of the poly A tail and guanine repeats to the mature mRNA so that it now exits the nucleus to begin translation.

What is the order of actions by rna polymerase?
Binds to DNA, makes mRNA from DNA, detaches
A mutation within a gene that will insert a premature stop codon in mRNA would?
Most likely result in mRNA that could not be translated and thus would not give rise to any proteins
Why are many types of RNA found in some cells with only one DNA?
There are different types of RNA that have different functions. Ribosomal RNA (rRNA) makes ribosomes, the site of protein synthesis; messenger RNA (mRNA) transcribes the DNA code into a strand of mRNA and will attach to a ribosome where transfer RNA (tRNA) translates the mRNA code by bringing amino acids to their appropriate place based on the mRNA code.
