Helmet_hair Posted June 24, 2006 Posted June 24, 2006 with DNA tests confirming Harriet's age but showing she came from an island that Darwin never visited. This might be a stupid question, but how do you get the age from DNA?
Corp000085 Posted June 24, 2006 Author Posted June 24, 2006 This might be a stupid question, but how do you get the age from DNA? 713542[/snapback] Oh geez, now you've got me thinking back to freshman year biology... It's a distant memory, so someone correct me if i'm wrong, but here we go... The ends of each strand of DNA [insert vocabulary word here] are used to start and stop DNA replication. With each replication, you add a piece of DNA as a byproduct [again, someone hook me up with the correct terminology]. Therefore, you can look at the ends of the dna strands to calculate the age of the organism.
Just Jack Posted June 24, 2006 Posted June 24, 2006 You scared me with the thread title. I thought you meant Cablelady died.
IDBillzFan Posted June 24, 2006 Posted June 24, 2006 This might be a stupid question, but how do you get the age from DNA? 713542[/snapback] You cut it in half and count the rings.
/dev/null Posted June 24, 2006 Posted June 24, 2006 This might be a stupid question, but how do you get the age from DNA? 713542[/snapback] ask its age and it will count by stamping its foot
cåblelady Posted June 24, 2006 Posted June 24, 2006 You scared me with the thread title. I thought you meant Cablelady died. 713551[/snapback] Phew. Me, too.

Each replication some of the telomere is lost. The shorter the telomere, the older the DNA. Yes i am a dork.
kegtapr Posted June 24, 2006 Posted June 24, 2006 Am I really reading a RIP thread for Aaron Spelling...creator of crappy womens tv? Yah, yeah...Starsky and Hutch and Charlies Angels.....doesn't make up for the crap though.
/dev/null Posted June 24, 2006 Posted June 24, 2006 Yes i am a dork. 713594[/snapback] yeah but what does that have to do with your knowledge of DNA
Wacka Posted June 24, 2006 Posted June 24, 2006 Telomeres are short repeated DNA sequences (maybe 10-20 bases in length) at the ends of chromosomes. The way the machinery in the cell copies the DNA, several repets are lost everytime the cell divides. The enzyme is not 100% effiient, so some is lost. This sort of acts like the aglet (cap) at the end of a shoelace to stop it from fraying. In general, long lived (slow growing ) animals have longer telomeres than short living animals. Flies that live a day or two have very short or no telomeres. Mice have longer ones and humnas have even longer ones. In some cancers the telomerase (enzyme that repairs the telomere) is very active and the cell does not die after the normal # of divisions. most cells in your body only divide about 50 times or so in your lifetime. You cannot tell age from this. Tortises and fish add rings to thier sales and shells like a tree. They probably figured its age from the rings. That ends your molecular biology lesson for today!
UConn James Posted June 24, 2006 Posted June 24, 2006 The third is Patsy Ramsey (mother of JonBenet). Cancer sucks.
meazza Posted June 24, 2006 Posted June 24, 2006 You scared me with the thread title. I thought you meant Cablelady died. 713551[/snapback] Me too. Thank God.
Corp000085 Posted June 24, 2006 Author Posted June 24, 2006 The third is Patsy Ramsey (mother of JonBenet). Cancer sucks. 713626[/snapback] and the fourth is the son of the old guy that anna nicole smith married... blunt force trauma caused by dropping of gigantic mammory glands on face.
kegtapr Posted June 24, 2006 Posted June 24, 2006 and the fourth is the son of the old guy that anna nicole smith married...blunt force trauma caused by dropping of gigantic mammory glands on face. 713697[/snapback] Sweet......that means we get two more. This is a good day.
BILLS4LIFE Posted June 25, 2006 Posted June 25, 2006 You scared me with the thread title. I thought you meant Cablelady died. 713551[/snapback] Me,too. FCOFL,dont EVER do that again!!!!!!!!!!!!!!!!!!!!!!!!!!
The Poojer Posted June 25, 2006 Posted June 25, 2006 i may catch schidt for this but i think 1/2 of the alibi behind jonbenet went with patsy, i think she and her husband are involved in her death big time The third is Patsy Ramsey (mother of JonBenet). Cancer sucks. 713626[/snapback]
R. Rich Posted June 26, 2006 Posted June 26, 2006 You scared me with the thread title. I thought you meant Cablelady died. 713551[/snapback] That's certainly something to joke about.
buckeyemike Posted June 26, 2006 Posted June 26, 2006 Scared me, too. First Harriet I thought of was Cablelady. As far as Patsy Ramsey is concerned, neither her DNA nor John Ramsey's was found near their daughter's body. DNA was found, but there has not been a match. However, I think Patsy Ramsey may have known something she has now taken to her grave. Mike
