Q
Rna structure
A
Ribonuceluic acid also a polymer made of nucleotides
Single relatively short polynucleotide chain
Penrose sugar -ribose
Organic bases -adenine ,guanine ,cytosine ,and uracil
2
Q
3 types of rna
A
mRNA
rRNA
tRNA
3
Q
mRNA
A
Messenger rna to transfer genetic informstion from dna to ribosomes
4
Q
Rrna
A
Ribosomal rna to form ribosomes with proteins
5
Q
tRNA
A
Transfer rna to bring about protein synthesis
6
Q
Similarities dna and rna
A
-polynucleotide mononucleotides linked by phosphodiester bonds
Via condesnation reactions
7
