Molecular weight for DNA and protein

Edited by Chang Zhu
Oligonucleotide (singe-stranded)

Molecular weight (Dalton) ~ 309 * length of the oligo

Double-stranded DNA

Molecular weight (Dalton) ~ 618 * length of the DNA


Molecular weight (Dalton) ~ 110 * length of the protein

DNA/Protein conversion

1 kb ORF ~ 37 kDa protein
