An intron is a DNA region within a gene that is not translated into protein. After intron splicing (ie. removal), the mRNA consists only of exon derived sequences, which are translated into a protein.
Mutations in introns are less likely to affect phenotype because introns are not translated into protein, unlike exons which contain coding regions for proteins. Introns are involved in regulation of gene expression through processes such as alternative splicing, but mutations within introns typically have a more subtle impact on gene expression compared to mutations in coding regions (exons).
Yes they are. Exons are expressed.
Exons, after the introns have been cleaved.
The CFTR gene has 27 exons and 26 introns. Introns are non-coding sequences that are spliced out during mRNA processing, while exons are coding sequences that are retained in the final mRNA transcript.
The codes for proteins are found in the exons of a gene. Exons are the coding regions of a gene that are transcribed into mRNA and translated into proteins. Introns, on the other hand, are non-coding regions that are spliced out during RNA processing and do not contribute to protein synthesis.
Correct. The mRNA transcibed from the DNA in the nucleus has both exons and introns; the introns are taken out and the exons are left in. The mended exons exit the nucleus and the introns stay in the nucleus. Only the exons are translated at the ribosomes. (In Eukaryotic cells only)

Exons are the parts of a gene that are kept and expressed, while introns are the parts that are removed during the process of splicing.

Yes they are. Exons are expressed.
To identify introns and exons in a sequence, one can use bioinformatics tools that analyze the sequence for specific patterns and characteristics associated with introns and exons. These tools can identify regions with known splice sites, coding sequences, and non-coding sequences to differentiate between introns and exons. Additionally, comparing the sequence to a reference genome can help in identifying these regions accurately.
Exons, after the introns have been cleaved.
After transcription, the mRNA is processed by the spliceosome, which splices out the introns (because introns are not part of the coding sequences for protein), and "stitches" the exons together to form the final transcript that is sent to the ribosome for translation.
During the process of RNA splicing, introns are spliced out, while exons are joined together to form the mature mRNA molecule.

yup
The CFTR gene has 27 exons and 26 introns. Introns are non-coding sequences that are spliced out during mRNA processing, while exons are coding sequences that are retained in the final mRNA transcript.
