Molecular Genetics: Part 4: Structure of the RNA Flashcards
How many strands does the structure of an RNA has?
One strand.
Does the RNA have the same nitrogenous bases as the DNA?
No, Uracil replaces Thymine.
What are the three types of RNA?
mRNA, tRNA, and rRNA.
What is the function of the mRNA?
It carries out messages directly from the DNA in the nucleus to the cytoplasm during protein synthesis.
What is the triplet nucleotides of mRNA called?
They are called Codons.
What is the tRNA shaped like?
It is shaped like a coverleaf.
What is the function of a tRNA?
It carries Amino Acids to mRNA at the ribosome in order to form a polypeptide.
What is the triple nucleotide in tRNA called?
It is complementary to that of mRNA and are called Anticodons.
What is the function of rRNA?
It is structural and along with proteins, it makes up the ribosomes.
