Cell (concept)
Morphological and functional unit of all living things.
Smallest element considered alive.
Modern Cell Theory
+ Smallest living unit of all organisms.
+ living things are made of cells.
+ cells come from other pre existing cells
Prokaryotic cells
Small, simple
Unicellular
Sex and asex reproducción
No nucleus, no membrane bound organelles

DNA
Deoxyribonucleic acid is the molecule that carries
genetic information for the development and functioning of an organism
Cuantos cromosomas hay cada humano y cuantos en cada gameto
46 humano (zygoto)
C/gameto: 23
RNA
Ribonucleic acid is a nucleic acid present in all living
cells that has structural similarities to DNA. RNA is a single-stranded.
Types of RNA
Messenger RNA (mRNA)
Ribosomal RNA (rRNA)
Transfer RNA (tRNA)
Bases of RNA (atached to sugar)
(C) Cytosine
(A) Adenine
(G) Guanine
(U) Uracil
Bases of DNA
C: Cytosine
A: Adenina
G: Guanina
T: Thymin
