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.
Are exons or introns spliced out during the process of RNA splicing?
During the process of RNA splicing, introns are spliced out, while exons are joined together to form the mature mRNA molecule.
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 is the name of the remaining pieces after introns have been cut out of RNA molecules that are spliced together?
The introns are cut out in the spliceisome and the exon portions are spliced together. A poly adenine tail is added to one end and a modified guanine cap added to the other end. Then the mRNA leaves the cell nucleus and heads for the cytoplasm and a ribosome.
What are the remaining pieces after intones have been cut out of RNA molecules that are spliced together?
Exons
What is spliced together during RNA processing?
Messenger RNA.

Which one exons or introns is spliced out when primary RNA is processed?
The introns are the sections which are spliced out to create the mature form of mRNA.
Are all RNA translated?
No, not all RNA molecules are translated into proteins. Some RNAs, such as transfer RNA (tRNA) and ribosomal RNA (rRNA), have roles in the process of translation itself rather than being the templates for protein synthesis. Additionally, some RNA molecules function in processes like gene regulation and serving as enzymes (ribozymes).

During the process of RNA splicing, introns are spliced out, while exons are joined together to form the mature mRNA molecule.
What is the term for RNA or DNA regions that are spliced together during modification?
MOLECULE
What is cut out of RNA molecules?
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 might be an advantage of RNA splicing?
the spliced exons are rejoined together and form a smaller mRNA.
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.
