A question regarding PCR

Hello everyone. Let's say I have this microsatellite DNA sequence: 5’-acatttg CTT CGTACACAAC TGTGCGAACA TGC caacctca tgcaacctca cacacacaca ... where primers should attach are written in capitals. My question is how many base pairs the amplified product will have, but it's not clear to me how to answer ...

Re: Virology - Calculations

**A virus has a genome of 1.184 MB (1184 kb) of double stranded DNA. 90.5% is coded into 1262 ORFs. What would be the average size of a coded protein in kiloDaltons? -1184 kb is 1184000 bases times the 660 Da per base pair gives 7.8144x10^8Daltons... Not sure where to ...
