The videos center on Pinky's certification and experience in teaching science at the high school level. Pinky's teacher certification is in grades 4-8 science and 8-12 composite science (encompassing biology, chemistry, and physics). Amoeba Sisters videos only cover concepts that Pinky is certified to teach, and they focus on her specialty: secondary life science. For more information about The Amoeba Sisters, visit: http://www.amoebasisters.com/about-us.html We cover the basics in biology concepts at the secondary level.

Realidad aumentada del cerebro: nucléolo

REALIDAD AUMENTADA DEL CEREBRO EL NÚCLEO DE LA NEURONA: EL NUCLÉOLO Sexta edición de un material gratuito que les permitirá conocer nuestro cerebro y sus áreas de un modo muy original: lo podrán ver en 3D e interactuar con su imagen desde todos sus ángulos, a través de un procedimiento conocido como realidad aumentada. Para poder hacerlo solo necesitarán una cámara web y la impresión de una hoja con un código QR. Instructivo de uso: 1) Descargar e instalar el programa Viewer, según sea el sistema operativo de su computadora. WINDOWS: http://author.aumentaty.com/sites/default/files/Downloads/AumentatyViewerSetup_1.3.exe MAC: http://author.aumentaty.com/AumentatyViewer.dmg 2) Descargar el siguiente archivo (nucleolo-RA.rar): http://bit.ly/2szbIbZ 3) Descomprimir el archivo descargado (nucleolo-RA.rar) e imprimir el instructivo (Instructivo nucleolo.pdf). 4) Abrir el archivo Cuerpo celular de la Nucleolo.atx2 (previamente necesitará instalar el Viewer). 5) Acercar la imagen impresa a la cámara web (aproximadamente a 30 cm de distancia). ------ El núcleo de la neurona: el nucléolo El nucléolo puede definirse como la expresión de la transcripción del ácido ribonucleico (ARN) prerribosómico por los organizadores nucleolares y de la maduración posterior de ese ARN hasta convertirse en ARN ribosómico. Se corresponde con una formación densa dentro del núcleo, observada en diversos tipos celulares. La proporción de ARN en el nucléolo es muy variable y depende del tipo celular y del estado funcional. Se estima como valor medio un 10%, aunque en algunas células puede alcanzar el 30%. El componente mayoritario son proteínas, las cuales constituyen prácticamente el resto del nucléolo.

DNA Replication
 
10:10
Paul Andersen explains how DNA replication ensures that each cell formed during the cell cycle has an exact copy of the DNA. He describes the Meselson-Stahl experiment and how it showed that DNA copies itself through a semi-conservative process. He then explains how multiple enzymes, like DNA polymerase, helicase, primase, ligase, and single strand binding proteins copy DNA. He also differentiates between the leading and the lagging strand. He explains how DNA is anti-parallel in nature and how eukaryotic cells have multiple origins of replication.
