Did you know that, if not, the DNA of a single cell would be more than 2 meters long? DNA is mainly made up of four chemical substances: adenine, thymine, guanine and cytosine, which are linked in a very specific way: A with T, C with G.

To understand what DNA is, we must imagine two chains that join together forming a double helix or a spiral staircase; This was first described in 1953 by James Watson and Francis Crick, which was a milestone in the history of biology. Many, thousands, millions of adenines, thymines, guanines and cytosines unite forming a sequence that follows a certain order such as AAATTCGAGTCAATTGCCTATCCTCGAGTCAACCTATCCA. The complete sequence of these chemical substances makes up our genetic code, our genome and certain sequences of these "letters" give rise to "phrases" known as "genes".]]> 2020-08-05 14:41:17 UTC https://padlet.com/lauravalentinalopezvelasquez/urf5rumykyx9odta/wish/670195842 lauravalentinalopezvelasquez https://padlet.com/lauravalentinalopezvelasquez/urf5rumykyx9odta/wish/675946384 2020-08-11 16:49:11 UTC https://padlet.com/lauravalentinalopezvelasquez/urf5rumykyx9odta/wish/675946384 lauravalentinalopezvelasquez https://padlet.com/lauravalentinalopezvelasquez/urf5rumykyx9odta/wish/675982037 2020-08-11 17:09:40 UTC https://padlet.com/lauravalentinalopezvelasquez/urf5rumykyx9odta/wish/675982037 lauravalentinalopezvelasquez https://padlet.com/lauravalentinalopezvelasquez/urf5rumykyx9odta/wish/680749661 2020-08-14 17:57:10 UTC https://padlet.com/lauravalentinalopezvelasquez/urf5rumykyx9odta/wish/680749661 lauravalentinalopezvelasquez https://padlet.com/lauravalentinalopezvelasquez/urf5rumykyx9odta/wish/684711062 2020-08-18 13:22:10 UTC https://padlet.com/lauravalentinalopezvelasquez/urf5rumykyx9odta/wish/684711062
