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.
The three types of RNA include; messenger RNA (mRNA), RNA polymerase, and transfer RNA (tRNA).
The RNA molecules that attach the amino acid to the protein chain are usually soluble.
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 nucleotides, which are the building blocks of RNA molecules. Nucleotides are connected in a specific sequence to form the RNA molecule.
Adenine occurs in both RNA and DNA molecules. It is uracil that replaces thymine in the RNA molecule.
Exons
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.
Thymine is a nucleotide that occurs in DNA molecules but not in RNA molecules. In RNA, thymine is replaced by uracil.
Yes, transcription requires RNA polymerase for the synthesis of RNA molecules.
Uracil replaces thymine in RNA molecules.
The type of sugar used in RNA molecules is ribose.
RNA molecules have many functions, but in the majority of cells most RNA molecules are involved in just one job- protein synthesis.
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
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.
Mi RNA
The three types of RNA include; messenger RNA (mRNA), RNA polymerase, and transfer RNA (tRNA).
The RNA molecules that attach the amino acid to the protein chain are usually soluble.
