Transcription and Translation Flashcards
(12 cards)
What bases does RNA use?
Guanine, cytosine, adenine and uracil
Is RNA shorter or longer than DNA?
Shorter
What is the purpose of a gene??
its a segment of DNA that codes for a protein
Where does the transcription of DNA to RNA happen?
In the nucleus
Where does the translation of mRNA happen?
cytoplasm (at the ribosome)
what does the ‘m’ in mRNA represent?
messenger - representing the fact that RNA carries DNA information to the cytoplasm to make proteins
In translation (RNA to protein) what loose bases attach to the RNA strand?
Anti-codons
OR also known as:
pieces of tRNA - loose threesomes of bases that have been recycled from broken down strands of RNA
What is attached to the tRNA that is vital for the final steps in creating protein?
Amino acids - there are about 20 different amino acids that could be attracted to the RNA threesomes
What organelle does the mRNA pass through to get attached to the matching tRNA/amino acids?
Ribosomes, in the cytoplasm
Every three nucleotides (anti-codons) have how many amino acids?
One aa
so for example, there could be 36 bases in the RNA, meaning there would be a chain of 12 amino acids
What does the ‘t’ in tRNA represent??
transfer, as it transfers the carried amino acid to the growing amino protein chain
