What is Meiosis?
Meiosis is cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.

What is the first Phase of Mitosis?
Prophase

I won two Nobel Prizes in Chemistry: one for my work on the structure of protein and another for work on the determination of base sequences in nucleic acids. Who am I?

What is Cytokinesis?
Cytokinesis separates the cytoplasm and cell membrane.

Even though he added an extra strand to the structure of DNA, he ultimately won two Nobel Prizes: the Nobel Prize in Chemistry and the Nobel Peace Prize
Linus Pauling

Meselson and Stahl invented this new technique in their quest to prove that DNA replication is semiconservative.
Density gradient centrifugation

I showed that RNA could act as its own catalyst. Because of my work, it is no longer correct to state, “all enzymes are proteins”. Who am I?

Where does Meiosis Result in?
Meiosis results in 4 haploid daughter cells.

What is Mitosis?
Mitosis is cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.

Think of this Nobel-Prize winning scientist who figured out the process of transposition in corn chromosomes the next time you’re munching away at the movies.

I first isolated DNA using pus collected from bandages at a local hospital. Since white blood cells are a major component of pus, they were my source of DNA. :(

The “fly room” at Columbia University was established through my efforts. Imagine working in a room filled with bottle after bottle of fruit flies!

Where does crossing over occur?
Crossing over occurs in Prophase 1.

In which phase does cytokinesis begin?
In Telophase

What phase is after Metaphase?
Anaphase.

I found that some viruses have an RNA-dependent DNA polymerase that was later named “reverse transcriptase.” I was one of three who shared in the 1975 Nobel Prize in Physiology or Medicine. Who am I?

We worked together to demonstrate how genes work during development to change a single egg cell into a complex organism. Follow our experiment and find out what the names of the stages are that a fruit fly goes through when maturing from a fertilized egg to an adult.
