What RNA polymerase makes rRNA?
What RNA polymerase makes rRNA?
The task of transcribing nuclear genes is shared between three RNA polymerases in eukaryotes: RNA polymerase (pol) I synthesises the large rRNA, pol II synthesises mRNA and pol III synthesises tRNA and 5S rRNA.
What is the function of RNA polymerase?
RNA polymerase I transcribes the genes that encode the structural RNAs for the subunits of the ribosome. RNA polymerase II transcribes the genes that encode proteins as well as a subset of small RNAs.
Which of the following rRNA is not synthesized by RNA polymerase I?
RNA polymerase 1 (also known as Pol I) is, in higher eukaryotes, the polymerase that only transcribes ribosomal RNA (but not 5S rRNA, which is synthesized by RNA polymerase III), a type of RNA that accounts for over 50% of the total RNA synthesized in a cell.
What is the difference between rRNA and mRNA?
mRNA provides a template for gene coding during protein synthesis, tRNA carries the amino acids to the ribosomes, which has to be added to the polypeptide chain and rRNA forms ribosomes along with proteins….Difference between mRNA, tRNA and rRNA.
mRNA | tRNA | rRNA |
---|---|---|
Site of synthesis is the nucleus | Produced in the cytoplasm | Found in ribosomes |
What is full meaning of RNA?
ribonucleic acid
How many types of RNA do we have?
3 types
What are 3 types of RNA and what do they do?
Three major types of RNA are mRNA, or messenger RNA, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled …
What does each RNA do?
There are three types of RNA involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribisomal RNA (rRNA). All three of these nucleic acids work together to produce a protein. Each codon encodes for a specific amino acid, except for the stop codons, which terminate protein synthesis.
What is an Anticodon give an example?
A sequence of three adjacent nucleotides located on one end of transfer RNA. It bounds to the complementary coding triplet of nucleotides in messenger RNA during translation phase of protein synthesis. Supplement. For example the anticodon for Glycine is CCC that binds to the codon (which is GGG) of mRNA.
