Does intron removal take place in the nucleus?

Yes, intron removal takes place in the nucleus. In eukaryotic cells, the process of RNA splicing, which involves the removal of introns from pre-mRNA, occurs in the nucleus before the transcript is transported to the cytoplasm for translation.


What is a splicing gene?

Gene splicing is the removal of introns(intervening sequences) from the primary trascript of a discontinuous gene during the process of Transcription.Gene splicing is the process of chemically cutting DNA in order to add bases to the DNA strand. The DNA is cut using special chemicals called restriction enzymes, which there are thousands of, and each one has its own, unique and specific code of DNA that it can cut.TRANSLATION: taking pieces of DNA from one or more organisms then combining them to create new DNA.


Does introns have complementary sequences in DNA?

Introns do not have specific complementary sequences in DNA. Introns are non-coding regions of a gene that are removed during the process of mRNA splicing. Their removal allows for the exons (coding regions) to be joined together to form the mature mRNA transcript.


Do protists have lysosomes?

Yes, protists have lysosomes. Lysosomes are membrane-bound organelles that contain digestive enzymes to break down waste materials and cellular debris in the cell. Protists use lysosomes for intracellular digestion and waste removal, like other eukaryotic organisms.


Why did the modification of leaves into spines happened?

The modification of leaves into spines in certain plant species is usually a response to environmental pressures such as limited water availability or herbivory. Spines help reduce water loss by decreasing the surface area exposed to the sun, and they act as a defense mechanism against herbivores by making the plant less palatable or difficult to consume.

How is DNA removal achieved in the process of genetic engineering?

In genetic engineering, DNA removal is achieved by using enzymes called restriction enzymes to cut out specific sections of DNA from a gene. These enzymes act like molecular scissors, cutting the DNA at specific sequences. The removed DNA can then be replaced with new DNA sequences, allowing scientists to modify the genetic makeup of an organism.

RNA splicing involves the?

removal of introns and joining of exons in pre-mRNA to produce mature mRNA that can be translated into a protein. This process is carried out by a complex called the spliceosome, which recognizes specific sequences at the ends of introns to facilitate their removal and joining of exons. RNA splicing plays a crucial role in generating protein diversity and regulating gene expression.

What is an aminoxylation?

An aminoxylation is an alternative term for a nitrosylation, the reaction of nitric oxide with a biological compound, especially with a sulphur containing part of a protein as a posttranslational modification.


True or False 'Addition or removal of phosphate groups to amino acids with alcohol groups represents a mechanism by which protein activity can be regulated.'?

True. Phosphorylation, which is the addition or removal of phosphate groups to amino acids with alcohol groups, is a common post-translational modification that can regulate protein activity by changing its structure and function.


What genetic information cannot be obtained from a punnett square?

a- Amino acid sequence of the protein.If there is NO intervening sequence and you know the promoter identity to establish the start site for protein synthesis--the gene sequence WILL give you this.If there ARE intervening sequences and you KNOW the mechanism/sequence signals for intron removal, then the gene sequence will give you this.HOWEVER, if you lack the knowledge that about intervening sequences (presence of, splicing sites, then you need more data than the gene sequence alone.b- Effects of mutation on gene function.This has the greatest possibility of being the correct answer BUT if you know anything about the structure/function of the protein then obtaining the gene sequence could tell you a lot about the protein.c- Relationship between two species.In general you can tell a lot about the relatedness of species by comparing specific genes across the evolutionary tree. However, that's not true if you only have the sequences for only two species and no others.This answer also can go both ways. The questions here are1. Is the gene very highly conserved throughout evolution or not? If it is very highly conserved then it may not have enough sequence variation to be useful. If it is not highly conserved, there may be too much variation to prove useful.2. Are you allowed to use noncoding sequences? This depends on what the working definition of "gene" is for this question. In general, noncoding sequences have fewer functional constrains on them and sequence variations are collected in these regions.d- Cellular location of the protein.If you are allowed to tap into the extensive knowledge in biochemistry/molecular biology about leader and other sequences in proteins that specify targeting to a cellular location then the gene sequence allows you to predict the cellular location of proteins.


What is the function of snRNP?

The action of snRNPs is essential to the removal of introns from pre-mRNA, a critical aspect of post-transcriptional modification of RNA, occurring only in the nucleus of eukaryotic cells. Additionally, U7 snRNP is not involved in splicing at all, as U7 snRNP is responsible to process the 3′ stem-loop of histone pre-mRNA.

What happens to the terminal methionine in most proteins that are produced?

Methionine is an important amino acid that helps to initiate messenger RNA as the standing in the N terminal position. Removal of the n terminal is the earliest possible chemical modification that can occur in protein synthesis.
