Mystery Behind How Nuclear Membrane Forms During Mitosis Solved

Link:http://www.sciencedaily.com/releases/2007/09/070915100302.htm

Summary:Just how a dividing cell rebuilds the nuclear envelope, the protective, functional wrapping that encases both the original and newly copied genetic material, has been a source of controversy for the last 20 years.

Mitosis/Meiosis
What are the differences between mitosis and meiosis?Mitosis -cell division including division of the nucleus and the cytoplasm.Meiosis-cell division in sexually reproducing organisms

What problems can arise if either of these processes is not controlled properly? The cell wont be able to divide.

List three things you learned from this article in your own words.During mitosis, the nuclear envelope disintegrates, The chromosomes are pulled apart and the cell starts to divide,individual tubules of the endoplasmatic reticulum bind directly to chromatin.

What impact would the absence of this process have on the cell?The organsim will die

Summary: Researchers at the University of California have found three-dimensional structure of an RNA enzyme. It carries out a fundamental reaction required to make new RNA molecules. It the first self-replicating molecule.

DNA/ RNA
What are the major functions of nucleic acids in the cell?Identifie the DNA

What are the differences in RNA and DNA? RNA acts as a messenger,DNA carries the material

List three things you learned from this article in your own words.That the structure of an RNA enzyme, is a ribozyme, we may have the first self-replicating molecule in billions of years

What impact would the absence of this organelle have on the cell? None

Summary: researchers and others has found out that bacteria employ a type of DNA modification we have never seen before.At first bacteria didnt have a kind of DNA . Now we have found that they my do.

What are the major functions of nucleic acids in the cell?Identifie the DNA

What are the differences in RNA and DNA? RNA acts as a messenger,DNA carries the material

List three things you learned from this article in your own words.Bacteria has DNA, nature has been using phosphorothioate modifications,

Good Behavior, Religiousness May Be Genetic

Link:http://www.sciencedaily.com/releases/2007/04/070405170133.htm

Summary: A new study shows that good behavoir my be passed genetically not by religion.After studying the behavoirs of two adults twins. They had found, while altruistic behavior and religiousness tended to appear together.

Mendel and Genetics
Explain the phenomenon being described in the article.behavoir is a trait that is passed

What is the difference between a genotype and a phenotype?Genotype is the formular,Phenotype is the apperence

List three things you learned from this article in your own words.Behavoir is passed, no specif gene for religion,individuals do have biological predispositions

What impact would the not understanding genetics have on medicine or agriculture?There will be less medicine and food

Climate Change Predicted To Drive Trees Northward

Link:http://www.sciencedaily.com/releases/2007/12/071203090131.htm

Summary:Trees in West Virginia are facing a deadly situation. If nothing is did for them then they will be moved northern, and shrink the range by half becauese of the climate. The trees dispersing their progeny to more favorable locations will eventually move.

Climate Change
What are some ways this phenomenon could be stopped? It says all trees will do this

Is there anything you could do to contribute to the reversal. No

List three things you learned from this article in your own words.Trees can move, All trees do this, Climate has a big affect

What impact would the continuance of these process have on the biosphere?Our trees will decrease

Progress Toward Artificial Photosynthesis

Summary: We are trying to do what plants do best and use it. Plants go through a process called photosynthesis. This process takes CO2 and turns it in to good use necessary for the plant to survive. If humans could do this it is no telling what we would do.

Photosynthesis
What is the chemical equation for photosynthesis? 6CO2 + 6H2O ------> C6H12O6 + 6O2

What organelles are involved in this process? Chloroplast
List three things you learned from this article in your own words.We can make it atifical,the equation,
What impact would the absence of this process have on the biosphere?Makes more than sugar
