DNA AND PROTEIN SYNTHESIS Flashcards
1
Q
structure of rna
what does uracil replace?
A
long single strand
thymine
2
Q
advantages of mRNA instead of DNA for protein synthesis
A
shorter and contains uracil- breaks down quickly so no excess polypeptide forms
contains no introns
single stranded and linear- ribosome moves along the strand, trna binds to exposed complementary bases
3
Q
structure of tRNA
A
80 nucleotides long
clover leaf shape
one end is anti codon the other is the amino acid binding site
