What is mean by 2c or 4c in DNA duplication & increase in chromosome number??
@ toshikaactually what happens when the dna replication starts , the dna molecule function as a template and form carbon copies .thats the dna contains will double from 1C TO 2C in the case of haploid cells . and in the case of diploid cell , it will grow from 2C to 4C . as a result duplicate set of genes are formed. HOPE IT CLEARS YOUR DOUBT ALL THE BEST ..
HI DEARACTUALLY C IS THE UNIT OF DNA MEASUREMENT . YOU CAN CALL IT AS PICOGRAM. AS WE MEASURE THINGS IN KILOGRAM , DNA IS MEASURED IN PICOGRAM {c}.WHEN DNA CONTENT DOUBLES WE CALL IT AS DNA CONTENT HAS CHANGED FRON 2C TO 4C.IT OCCURS AT TIME OF DIVSION. NOTE THAT CHROMOSOME NUMBER STILL REMAINS SAME . ONLY DNA CONTENT IS DOUBLEBAPPROVE MY ANSWER . POST IF STILL SOME DOUBT EXIST IN MIND
C is nothing, just a unit for DNA amount . In diploid it is consider as 2C And during replication in the S phase.. it becomes 4C .
