Introns are cut out of RNA molecules. Extrons are "spliced" together afterwards. Think of a long strand that is white with blue on the ends. The white of the strand is the intron, while the blue color are the extrons. The white color or the "intron" is cut out, and then the two blue strands merge together known as the extrons splicing together.
What else can I help you with?
What are three kinds of RNA molecules?
The three types of RNA include; messenger RNA (mRNA), RNA polymerase, and transfer RNA (tRNA).
Which RNA was soluble rna?
The RNA molecules that attach the amino acid to the protein chain are usually soluble.
Amino acids are picked up by special RNA molecules called?
transfer RNA (tRNA) molecules. These molecules have a specific sequence that matches with the codons on messenger RNA (mRNA) to ensure the correct amino acid is added during protein synthesis.
Rna contains what between the RNa?
RNA contains nucleotides, which are the building blocks of RNA molecules. Nucleotides are connected in a specific sequence to form the RNA molecule.
Does adenine nuleotide occur in DNA but not in RNA molecules?
Adenine occurs in both RNA and DNA molecules. It is uracil that replaces thymine in the RNA molecule.
What are the remaining pieces after intones have been cut out of RNA molecules that are spliced together?
Exons
What are the intervening sequence of RNA molecules that are cut out before the messenger RNA leaves the nucleus?
The intervening sequences of RNA molecules that are cut out before the messenger RNA leaves the nucleus are called introns. These introns are non-coding sequences that are spliced out of the pre-mRNA during the process of RNA splicing, leaving only the exons to form the mature mRNA that is then transported to the cytoplasm for translation.
Which of the nucleotides occurs in DNA molecules but not in RNA molecules?
Thymine is a nucleotide that occurs in DNA molecules but not in RNA molecules. In RNA, thymine is replaced by uracil.
Does transcription require RNA polymerase for the synthesis of RNA molecules?
Yes, transcription requires RNA polymerase for the synthesis of RNA molecules.
What does uracil replace in RNA molecules?
Uracil replaces thymine in RNA molecules.
What type of sugar is used in RNA molecules?
The type of sugar used in RNA molecules is ribose.
What is one job in which most rna molecules are involved?
RNA molecules have many functions, but in the majority of cells most RNA molecules are involved in just one job- protein synthesis.
What are two explanations for why some RNA molecules are cut and spliced?
1. making it possible for a single gene to produce several different forms of RNA 2. It would make it possible for every small changes in DNA sequences to have dramatic effects in gene expression
What do slicer enzymes do?
Slicer enzymes are a type of enzyme that cleave RNA molecules at specific target sites. They are involved in RNA interference pathways and play a crucial role in regulating gene expression by degrading specific RNA molecules.
What RNA molecules is involved in regulation of gene expression?
Mi RNA
What are three kinds of RNA molecules?
The three types of RNA include; messenger RNA (mRNA), RNA polymerase, and transfer RNA (tRNA).
Which RNA was soluble rna?
The RNA molecules that attach the amino acid to the protein chain are usually soluble.
