Copier enzymes, commonly referred to as RNA polymerases, are responsible for synthesizing RNA from a DNA template during the process of transcription. They bind to specific promoter regions on the DNA and catalyze the addition of ribonucleotide triphosphates, creating a complementary RNA strand. This process is essential for gene expression, as it produces messenger RNA (mRNA), which serves as the template for protein synthesis. Additionally, RNA polymerases also play roles in synthesizing other types of RNA, such as rRNA and tRNA.
What else can I help you with?
What is the function of the enzymes RNA polymerase?
It catalyzes the bonding of RNA nucleotides.
Does lysosome contain RNA?
Yes, lysosomes do contain RNA. Some lysosomal enzymes and proteins are coded for by specific RNA molecules that are synthesized in the cell's nucleus and then transported to the lysosomes where they are translated into functional proteins.
Does the nucleus store enzymes?
The nucleus transcribes and releases messenger RNA signaling for the enzymes to be synthesized
Which organelle consists of a large number of RNA and enzymes?
Ribosomes. They are the location in which a large amount of RNA is synthesized and the synthesis of any cellular component needs a large amount of enzymes to speed up the process.
What enzymes are involved in gene expression?
Enzymes involved in gene expression include RNA polymerase, which synthesizes RNA from a DNA template during transcription. Additionally, various transcription factors and coactivators modulate RNA polymerase activity, facilitating or inhibiting the transcription process. After transcription, enzymes such as splicing factors and RNA ligases modify the RNA transcript, while ribosomes and associated factors are crucial for translation, the process of synthesizing proteins from mRNA.

Are enzymes are fats?
No, most enzymes are proteins, some of which are "decorated" with sugars. A few enzymes are composed of RNA.

What protects RNA from attack by cytoplasmic enzymes?
RNA molecules are protected from attack by cytoplasmic enzymes by various means such as the formation of ribonucleoprotein complexes, RNA-binding proteins that stabilize the RNA structure, and the presence of modifications like methylations and pseudouridylations that can shield RNA from degradation. Additionally, RNA can also be sequestered in specific cellular compartments such as the nucleus or ribonucleoprotein granules, which can provide protection from cytoplasmic enzymes.

What role do enzymes play in transcription?
Enzymes help regulate and facilitate the process of transcription by aiding in the unwinding of DNA, the formation of mRNA, and the proofreading of the newly synthesized RNA molecule. For example, RNA polymerase is an enzyme that catalyzes the formation of RNA by reading the DNA template strand. Various other enzymes are involved in modifying the newly synthesized RNA to ensure its accuracy and functionality.
What must happen to a DNA molecule before RNA ploymerase can make RNA?
The double strand helix is opened by enzymes called helicase and this allow the RNA polymerase to copy the DNA strand. The double strand helix is opened by enzymes called helicase and this allow the RNA polymerase to copy the DNA strand.
What is nature of ribozymes?
Ribozymes are RNA molecules that have catalytic activity, allowing them to accelerate specific chemical reactions. They are able to act as enzymes, performing functions such as RNA splicing, RNA cleavage, and peptide bond formation. This unique property of ribozymes highlights the versatility of RNA in both genetic information storage and biochemical catalysis.
