Answer: Portions called introns are removed and the remaining exons are spliced together
Explanation:
The messenger RNA obtained after transcription is known as primary transcribed RNA or precursor RNA, and it has to undergo modifications before exerting its function. This is called RNA processing or maturation.
In the DNA sequence, the coding content of a gene is not continuously distributed along the gene, but has discontinuities, called introns, whose sequence does not encode proteins.The parts of the sequence that encode proteins are called exons. Through a process called splicing (which is one of the modification that are part of the RNA maduration), the introns are eliminated and the exons are joined forming a mature messenger RNA molecule that will be used for protein synthesis.
So the exons are part of the region of a gene that is not separated during the cutting and splicing process and is therefore kept in the mature messenger RNA. Each exon codes a specific portion of the entire protein, so that the set of exons forms the coding region of the gene.
According to the CDC, tooth decayaffects more than one-fourth of U.S. children aged 2 to 5.Tooth decay is thedamage of the structure of the tooth which is caused by acids that are producedwhen sugar is being broken down by plaque bacteria in the mouth. Tooth decay is the primary cause of tooth loss in children in the UnitedStates.
The building blocks of nucleic acids are nucleotides, which consist of a sugar molecule, ribose or deoxyribose, a phosphate group, and a nitrogenous base, adenine, guanine, cytosine, thymine, or uracil.
Nucleotides are the building blocks of nucleic acids, such as DNA and RNA. They consist of a sugar, ribose or deoxyribose, a phosphate group, and a nitrogenous base, adenine, guanine, cytosine, thymine, or uracil.
Nucleotides link together through phosphodiester bonds, forming the backbone of nucleic acid chains. The sequence of nitrogenous bases along the chain encodes genetic information. Adenine pairs with thymine or uracil in RNA, while guanine pairs with cytosine, creating complementary base pairs.
Nucleotides play a crucial role in storing and transmitting genetic instructions, serving as the foundation for DNA and RNA molecules.

Answer:
A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
I found this on google because I am not the best at explaining things but I hope this helps :)
