What are the small bumps located on the portions of the endoplasmic reticulum?
They are ribosomes which translates messenger RNA into proteins
Does RNA look like ladder cut in half?
Yes! DNA is a double helix strand that is a full ladder. RNA is that ladder cut in half!
What do chromosome contain?
Chromosomes contain genes, regulatory portions, the centromere, the telomere and "junk DNA".
What functions do the carbohydrate portions of molecules perform?
The functions of carbohydrate portions of molecules include energy storage. It also functions as the backbone of RNA and DNA molecules. Carbohydrates also contribute to the structure of cell walls.
Are Exons Cut After Transcription In Eukaryotes?
No. The Ex in Exon refers to Expression.Introns are nucleotide sequences within genes that are removed by RNA splicing to generate the final mature RNA product of a gene.
What are portions of rna that are cut out and discarded?
introns
What are the small pieces of Dna and Rna which recognize and bind to small portions of Genes called?
sn - for Small Nuclear - Dna and sn Rna.
What are the small bumps located on the portions of the endoplasmic reticulum?
They are ribosomes which translates messenger RNA into proteins
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.
Does RNA look like ladder cut in half?
Yes! DNA is a double helix strand that is a full ladder. RNA is that ladder cut in half!
If the heart is cut so that superior and inferior portions result?
This would involve a transverse cut.
Describe how RNA is processed in eukaryotes What is the purpose of each step?
Introns are cut out, and the resulting exons are spliced together.Exons are cut out, and the introns are spliced together.Introns are cut out and spliced together at the end of the mRNA.Exons are cut out and transported to smooth endoplasmic reticulum.Introns are cut out and transported to the ribosomes
What function do carbohydrate portions of molecules perform?
The functions of carbohydrate portions of molecules include energy storage. It also functions as the backbone of RNA and DNA molecules. Carbohydrates also contribute to the structure of cell walls.
What do chromosome contain?
Chromosomes contain genes, regulatory portions, the centromere, the telomere and "junk DNA".
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 functions do the carbohydrate portions of molecules perform?
