Eukaryotic genes have regions called "introns" and "exons". Exons code for polypeptides (often specific domains or motifs), while introns don't code for anything (that we know of) and are removed.
mRNA splicing is the process where an mRNA molecule is cut up (usually by the "spliceosome") to remove the introns from an mRNA message. This is advantageous for us eukaryotes because we can recombine exons in different orders, and even combine exons from different genes to generate many proteins from a smaller number of genes.

How do introns and exons relate to RNA splicing?
Before the RNA leaves the nucleus, the introns are removed and the exons are joined together, producing an mRNA molecule with a continuous coding sequence. This process is called RNA splicing.
Does splicing occur in prokaryotes?
in prokaryotes only self spilicing and tRNA splicing are present there is no splicosomes are present.
What is self splicing?
Intron that itself is the source of the enzymatic activity necessary for it removal. Splicing mechanism of pre-mRNA involving group I introns.
What is the primary transcript of eukaryotic genes?
the primary transcript usually has a exons and introns which need to undergo splicing to remove the introns and re-splicing to join the exons ..after this process the resulting mRNA is a mature mRNA.
What is the corresponding mRNA sequence to ATGCCCTAAGTG of an unraveled section of DNA?
The corresponding mRNA sequence of ATGCCCTAAGTG is UACGGGAUUCAC

What sequence of mRNA would go with the DNA sequence of act?
If the DNA sequence is ACT, the complimentary mRNA sequence would be UGA

Why RNA splicing important?
Because DNA cannot fit through the pores of the nuclear membrane, it is too big, the mRNA copies off the specific parts needed and sends the information to where the body needs them. Without mRNA, you could not function properly.

The corresponding mRNA sequence of ATGCCCTAAGTG is UACGGGAUUCAC
When you compare an mRNA product of an unidentified organism with the gene you discover that the mRNA is much smaller than the actual gene coding for it Is the organism a bacteria or eukaryote why?
The mRNA product is shorter than the gene coding for it as a result of splicing. Therefore the organism in question is likely to be a Eukaryote, as Prokaryotes rarely undergo splicing.
What is exon skipping?
Exon skipping, also known as alternative splicing is a process whereby the exons are cut from a genetic sequence (pre-mRNA or hnRNA) and rearranged multiple ways into different mRNA molecules. This allows for a single gene to code for several proteins and isoproteins. Seen in Eukaryotes only.
What is directly responsible for the sequence of amino acids in a protein?
The sequence of codons in mRNA, or messenger RNA, is most directly responsible for the sequence of amino acids in a protein. Each codon is comprised of 3 nucleotides.
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 DNA sequence reads TGAAC Whatbis its mRNA sequence?
BBC is the DNA in a MRNA sequence. This is part of the body.
