The Nucleus

Controller of the Cell, House DNA, Creator of mRNA and rRNA, Proud supporter of Chromatin and Cell Division.

[The Nucleus @Sarah3Danny]

Chromatin is DNA and protein combined. Located in nucleus & condensed into chromosomes when its time for cell division. @murphyapbio

[The Nucleus @Sarah3Danny]

The nucleus starts the process of making proteins by mRNA which is passed on to many other organelles and eventually completed @murphyapbio

[The Nucleus @Sarah3Danny]

DNA is composed of 4 nucleic acid bases which are Adenine, Thymine, Guanine and Cytosine. They come together as a double helix @murphyapbio

Rough E.R. has ribosomes that can be defective & it only helps transport proteins. Not very helpful in a busy cell. @murphyapbio @JessanyAP

[The Nucleus @Sarah3Danny]

P.M. gets the easiest job,just has to transport materials in & out of cell. No wonder it doesn't make mistakes @murphyapbio @SydneyJade2016

Pearson Education Test Prep Series for AP Biology (Fred W. Holtzclaw, Theresa Knapp Holtzclaw) is our primary reference. @murphyapbio

Defective mitochondria are linked to cardiac problems & many other suspected diseases such as diabetes. @MitototheMax @murphyapbio

[The Nucleus @Sarah3Danny]

They can have defective enzymes that don't break down the material. Overcrowding happens & then deadly diseases @murphyapbio @cleanersomes

[The Nucleus @Sarah3Danny]

Without the nucleus in charge, the other organelles would have no directions and would not be able to function properly. @murphyapbio

[The Nucleus @Sarah3Danny]

DNA replication occurs in the nucleus, which provides the ability for organisms to pass on traits and for others to inherit. @murphyapbio

[The Nucleus @Sarah3Danny]

The nucleus itself is not part of the endomembrane system, however its double membrane nuclear envelope is. @murphyapbio

Ribosomes? why vote for the construction worker @Ribosome_2016 @murphyapbio

[Ribo~get~SOME @Ribosome_2016]

Lysosomes? why vote for the garbage man @murphyapbio

[The Nucleus @Sarah3Danny]

DNA replication errors are fixed by DNA polymerase & its enzymes that identify errors.Does @Ribosome_2016 have a mutation prevention system?

[The Nucleus @Sarah3Danny]

@Ribosome_2016 @murphyapbio Defective ribosomes cause disorders and diseases because of mutations in the proteins they produce.

[The Nucleus @Sarah3Danny]

Without the guidance of our DNA, ribosomes would be unemployed. Lack of mRNA from nucleus means no proteins. @Ribosome_2016 @murphyapbio

[The Nucleus @Sarah3Danny]

The nucleus directs all other organelles and without this direction they would never know what to do @murphyapbio
