The right answer is B.
Insertion is a genetic mutation characterized by the entrenchment of genetic material in a chromosome. The insertion size varies between a base pair and an entire sector of a chromosome moved to another. In the latter case, part of the genetic data of the first chromosome is erased. This can happen during an uneven jumping.
The embedding of nucleic bases in a gene makes it longer and shifts the reading of its data, which can modify its functioning in a harmful way, especially if the insertion occurs on the exon (fragments of an RNA primary presence in cytoplasmic RNA after splicing).
Answer:
Ο Α.
Sensory receptors in the skin detect the stimuli from the environment.
Explanation:
Simple process of elimination. Keratin is what makes up hair and nails. Muscles cannot detect temperature change, and connective tissue can't either. The sensory receptors that detect heat and cold are called thermoreceptors
The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
They are called CHNOPS elements which stands for Carbon, Hydrogen, Nitrogen, Oxygen, phosphorus, and Sulfur
