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.

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 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.
How are selfreplicating molecules such as RNA molecules in the RNA World hypothesis essential to the most popular hypotheses about the origin of life on Earth?
no clue buddy
Amino acids are picked up by special RNA molecules called?
transfer RNA (tRNA)
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?
Introns are cut out and then the exons are spliced together.
What are three types of RNA molecules?
The three types of RNA molecules include messenger RNA (mRNA), ribosomal RNA (rRNA) and transfer RNA (tRNA).
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.
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.
Molecules move between the nucleus and the cytoplasm through?
Water soluble molecules such as protein and RNA.
What RNA molecules is involved in regulation of gene expression?
Mi RNA
What are three kinds of RNA molecules?

Which of the nucleotides occurs in DNA molecules but not in RNA molecules?
Thymine
Which RNA was soluble rna?
The RNA molecules that attach the amino acid to the protein chain are usually soluble.
Is phosphate in RNA molecules?
Yes
What do you call molecules that carry out most cell function?
