What are two kinds of RNA?
There are lots of kinds with different functions, but main types are: 1. Regulatory RNAs 2. RNAs of transcription and DNA replication 3. RNAs involved in protein synthesis 4. Parasitic RNAs those are coding RNAs, there are also non-coding RNAs (ncRNA).
What are ncRNAs and how do they differ from RNAs that encode proteins?
Non-coding RNAs (ncRNAs) are a type of RNA molecule that do not encode proteins. They play various regulatory roles in the cell, such as controlling gene expression. In contrast, RNAs that encode proteins are called messenger RNAs (mRNAs) and carry the genetic information needed to produce proteins. The main difference between ncRNAs and protein-coding RNAs is their function - ncRNAs regulate gene expression without producing proteins, while protein-coding RNAs are translated into proteins.
Why eukaryotes need 3 RNA polymerase?
Each of the 3 RNA polymerase in eukaryotes perform a different function. For example, RNA pol 2 is involved in mRNA synthesis, RNA pol 1 synthesizes most rRNAs and RNA pol 3 synthesizes tRNNA, the 5S rRNA and other small nuclear RNAS. Eukaryotes are more complex than prokaryotes, hence why eukaryotes would require more RNA polymerases.
What types of RNA are present in protein synthesis?
All forms of RNA are involved in protein synthesis: mRNA, rRNA, and tRNA. Messenger RNA (mRNA) is the transcript with the codon sequences specifying which amino acids are needed and in what order. Transfer RNA (tRNA) binds to amino acids and brings them to the ribosome where the transcript is read and the protein assembled.
What is a functional RNA?
Functional RNA refers to RNA molecules that have specific roles in regulating gene expression and cellular processes, rather than mere information carriers like messenger RNA (mRNA). Examples of functional RNAs include transfer RNA (tRNA) for protein synthesis, ribosomal RNA (rRNA) for ribosome formation, and microRNA (miRNA) for gene regulation. These RNAs play crucial roles in various cellular functions and help maintain the overall health and functionality of the cell.
Are all the RNAs translated?
No, not all RNAs are translated. Some RNAs, such as transfer RNAs (tRNAs) and ribosomal RNAs (rRNAs), are involved in the process of translation itself, but not translated into proteins. Other types of RNAs, like microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), have regulatory functions in the cell and do not code for proteins.
What cleavage does lead have?
Lead does have cleavage. Specifically, lead-induced cleavage is an integral part of ribosomal RNAs, and performs at a neutral pH.

What kinds of genes are transcribed but not translated?
Genes that are transcribed but not translated include non-coding RNA genes, such as microRNAs and long non-coding RNAs. These RNAs can have regulatory functions in the cell without being translated into proteins. Another example is ribosomal RNA (rRNA), which is transcribed but not translated as it forms part of the ribosome structure.
Who discovered satellite RNAs?
sir frances laponial discovered satellite RNAS
What two types of Rna molecules carry the Dna Code?
Messenger Rnas and Transfer Rnas.
What has the author Maysoon Salama written?
Maysoon Salama has written: 'The isolation of Lactococcus lactis subsp. cremoris from nature with probes for 16S ribosomal RNAs' -- subject(s): Nucleic acid hybridization, Nucleic acid probes, RNA, Nucleotide sequence, Lactococcus lactis
What does the nucleolus do inside an animal cell?
Its main function is to produce the ribosomal-Rnas that are then exported to the cytoplasmically located Endoplasmic Reticulum to form Ribosomes which basically are the base for making proteins in all Cells.Ribosomes are made [primarily] from two rRnas [ribosomal Rnas] - which are made, in a concentrated fashion, in the nucleolus: the job of the nucleolus is to produce ribosomal Rna [in and of its many forms].

What are three different kinds of rnas?
their is rRNA, tRNA, and mRNA
Is RNA disposable?
Yes. RNAs are discarded or recycled after usage.
What are old factory cells?
old factory cells are The function of the nucleolus as a factory for assembling ribosomal subunits is well established, but many unrelated activities have been discovered over the past decade. Our understanding of the dynamics of nucleolar structure and its reassembly at the end of mitosis has recently advanced and the small nucleolar RNAs have been shown to be major players in the processing and modification of preribosomal RNA. Unexpectedly, the nucleolus also seems to play a role in nuclear export, sequestering regulatory molecules, modifying small RNAs, assembling ribonucleoprotein (RNP) and controlling aging.
