In eukaryotes, transfer RNAs (tRNAs) are essential molecules that play a crucial role in protein synthesis. They serve as adapters that translate the genetic code from messenger RNA (mRNA) into amino acids, facilitating the assembly of proteins at the ribosome. Each tRNA molecule is specific to one amino acid and contains an anticodon that pairs with the corresponding codon on the mRNA. Additionally, eukaryotic tRNAs undergo post-transcriptional modifications and processing before they are fully functional in translation.
What else can I help you with?
What enzyme transcribes tRNA in eukaryotes?
The enzyme responsible for transcribing tRNA in eukaryotes is known as RNA polymerase III. It specifically transcribes genes that encode transfer RNAs (tRNAs) as well as other small non-coding RNAs.
What is the base sequence at the 3' end of all tRNAs?
The base sequence at the 3' end of all tRNAs is CCA. This sequence is added post-transcriptionally during tRNA processing and is important for tRNA charging with the corresponding amino acid.
What are the cells called that have a nucleus and organelles?
There are two basic types of cells, prokaryotes and eukaryotes. Eukaryotes differ from prokaryotes in a few ways, but the biggest difference is that eukaryotes have a nucleus and prokaryotes don't.
Can eukaryotes be unicellular or multicellular?
Eukaryotes can be both unicellular and multicellular. Examples of unicellular eukaryotes include protists like amoebas and paramecia. Multicellular eukaryotes include plants, animals, and fungi.
Which describes a difference between prokaryotes and eukaryotes?
Eukaryotes have membranes around their organelles.
What enzyme transcribes tRNA in eukaryotes?
The enzyme responsible for transcribing tRNA in eukaryotes is known as RNA polymerase III. It specifically transcribes genes that encode transfer RNAs (tRNAs) as well as other small non-coding RNAs.
What eats eukaryotes?
Other eukaryotes may eat eukaryotes and some prokaryotes may eat eukaryotes.
Where is tRNA in the cell?
tRNAs produced in nucleus but they exported to cytoplasmwhere protein synthesis occurs.
What is the base sequence at the 3' end of all tRNAs?
The base sequence at the 3' end of all tRNAs is CCA. This sequence is added post-transcriptionally during tRNA processing and is important for tRNA charging with the corresponding amino acid.
Which has more lipids prokaryotes or eukaryotes?
eukaryotes
Animals are prokaryote?
No, animals are eukaryotes.
Are all eukaryotes large?
No, many eukaryotes are microscopic.
Are Planted prokaryotic?
No. They are eukaryotes.
What does tRNAs do?
tRNA delivers the amino acids to the ribosomes for incorporation into [nacent polypeptide] protein chains.
Are mitochondria in eukaryotes only?
Yes, Mitochondria are specific to eukaryotes.
Are fungi eukaryotes or prokayotes?
Eukaryotes, they have a nucleus, while prokaryotes do not.
Are humans classified as prokaryotes or eukaryotes?
Humans are classified as eukaryotes.
