What are two types of nucleic acid found the cell?
Two types of nucleic acids found in cells are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA stores genetic information and is typically found in the cell nucleus, while RNA plays a role in protein synthesis and can be found in the nucleus and cytoplasm.
What enzyme does transcription require?
Transcription requires the enzyme RNA polymerase. This enzyme synthesizes RNA by reading the DNA template strand and adding complementary RNA nucleotides, facilitating the formation of an RNA strand. In eukaryotes, multiple types of RNA polymerase exist, with RNA polymerase II being responsible for synthesizing messenger RNA (mRNA).
Which base is only found in RNA nucleotides?
Uracil is only found in RNA nucleotides. In DNA uracil is replaced by thymine.
What are round non membrane bound organelles found in prokaryotes and eukaryotes?
Round, non-membrane-bound organelles found in both prokaryotes and eukaryotes are ribosomes. Ribosomes are essential for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains. In prokaryotes, ribosomes are smaller and float freely in the cytoplasm, while in eukaryotes, they can be found free in the cytoplasm or attached to the endoplasmic reticulum, forming rough ER. Despite their structural differences, ribosomes play a crucial role in the cellular machinery of both types of organisms.
How many different RNA are found in cells?
There are three main types of RNA found in cells: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNA molecules play crucial roles in protein synthesis and gene expression within cells.
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.
Where is RNA made during transcription?
In prokaryotes, RNA is transcribed in the cytosol. In eukaryotes, RNA is transcribed in the nucleus.
What are two types of nucleic acid found the cell?
Two types of nucleic acids found in cells are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA stores genetic information and is typically found in the cell nucleus, while RNA plays a role in protein synthesis and can be found in the nucleus and cytoplasm.
Where are the types of RNA found?
mRNA, rRNA, tRNA

DNA and RNA are both types?
They are types of nucleic acids. DNA is found in the nucleus and RNA is found in the nucleolus (in the nucleus) and in the ribosomes. DNA codes for RNA, which codes for proteins which ultimately make up our body.
Which base is only found in RNA nucleotides?
Uracil is only found in RNA nucleotides. In DNA uracil is replaced by thymine.
What is only found in RNA?
uracil
In eukaryotes all of RNA are transcribed or produced in the?
In eukaryotes, all RNA molecules are transcribed in the nucleus. This includes messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). While some RNA molecules may undergo further processing and modification in the cytoplasm, their initial transcription occurs in the nucleus.
What is the nitrogenous base that is found only in RNA?
The nitrogen containing base that is found only in RNA is uracil. It takes the place of thymine in DNA
What are round non membrane bound organelles found in prokaryotes and eukaryotes?
Round, non-membrane-bound organelles found in both prokaryotes and eukaryotes are ribosomes. Ribosomes are essential for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Despite their structural differences, ribosomes play a crucial role in the cellular machinery of both types of organisms.
Where are strands of RNA made?
in eukaryotes, RNA is synthetised in the nucleus from DNA, using RNA-polymerase. in prokaryotes, RNA is synthetised in the cytoplasm (DNA has no nucleus), using RNA-polymerase as well.
