Why do the introns have to br removed?
Introns are the non-coding parts of the gene. If you didn't remove introns, the wrong protein may be produced because they allow more than one protein to be produced from a single gene.
What is the noncoding segement of a gene are cut out of an mRNA transcript?
Introns.
What is the name for sections of a structural gene that do not code for amino acids?
Introns
What is the name for a stretch of non coding DNA that interrupts the coding sequence of a gene?
introns
What does non coding RNA mean?
The non-coding sections of a gene are known as introns. The coding sections of a gene are known as exons.
What is the meaning of infronic's activity?
The term "infronic activity" refers to the presence of functional elements within introns, which are non-coding regions of a gene. These elements can have roles in gene regulation, alternative splicing, or other cellular processes. Infronic activity adds to the complexity of gene expression regulation beyond the coding regions of genes.
Why must introns be removed while the exons remain in the mRNA?
Introns are non-translated sections of a gene, i.e. they are not made into protein. The gene is stored in the chromosomes as DNA. When the corresponding protein is needed, the DNA is copied (transcribed) by RNA polymerase making a complementary copy of the gene made of RNA. This is then processed to remove the introns (the non-coding parts of the gene). It was long thought these introns hasdno use. However, there is evidence that they have a role in the processing of the RNA. In addition, introns allow more than one protein to be produced from a single gene. The RNA with the introns removed is now the messenger RNA (mRNA) which is transported out of the nucleus into the cytoplasm, where it is read by the ribosome, which produces the coded protein.

Which of these is a type of post-transcriptional regulation of gene expression?
Post-transcriptional regulation of gene expression can refer to the life of mRNA. You see, mRNA is transcribed into a protein in the cytoplasm, and if the mRNA only stays in the cytoplasm for a short period of time, then only some of the enzymes coded for on the strand can be created. So if the mRNA is programmed to die early, then only some of the proteins will be produced and only some genes will be expressed. It can also refer to the excision of introns and sometimes exons. pre-mRNA is usually edited by proteins to take out the introns, which are basically useless gene sequences (sometimes called junk DNA). Then the mRNA goes on to express the genes it codes for. But if the proteins take out introns and ALSO some exons, then some genes will be removed and not be expressed. This is another type of post-transcriptional gene regulation. Hope this helped!
What is the name for sections of a structural gene that do not code for amino acids?
Introns
Section of DNA within a gene that do not encode part of the protein that the gene produces are called?
Introns (the stuff between the exons), and UTR (Untranslated region, the stuff before the start codon, and after the stop codon).
The nuclear membrane's role in the regulation of gene expression involves?
Regulating the transport of mRNA to the cytoplasm
Sections of RNA molecules that are removed before eukaryotic gene becomes functional?
introns
What is the name for a stretch of non coding DNA that interrupts the coding sequence of a gene?
introns
What does non coding RNA mean?
The non-coding sections of a gene are known as introns. The coding sections of a gene are known as exons.
What are introns and extrons and how are they different?
Exon DNA encodes for the RNA included in the final mRNA transcript that encodes for proteins. Intron DNA is found within exons, but is spliced out as the mRNA molecule is processed.
