True or false. All cells divide the same number of times.

False

100
The stage in mitosis when all the chromosomes line up in the middle.
What is metaphase.
100
A tightly packed piece of DNA which is packed up and ready for the cell to divide.
What is a Chromosome?
100

The substance that is capable of transforming rough bacteria as studied by Griffith.

What is DNA?

100
What is expressed in gene expression?
Proteins
200

The stage of cell cycle when DNA is copied.

What is interphase? Or what is S phase?

200
The stage of mitosis where the sister chromatids separate.
What is anaphase?
200
Regions of DNA that code for traits like eye color, attached ear lobes, etc.
What is a gene?
200

Two people who used x-ray data to construct a double helix DNA model.

Who are Watson and Crick?

200
What enzyme is responsible for making mRNA from DNA? And what would it transcribe the following DNA sequence to? TACGCTGCTA How many codons are present?
RNA polymerase - AUG-CGA-GAU - 3
300
A disorder of the cell cycle that causes cells to grow and divide uncontrollably. If not treated the disorder will kill you.
What is Cancer.
300

The number of phases of mitosis.

What are 4?

300

What are the three parts to a nucleotide?

Sugar (ribose), base, and phosphate

300

Name the scientist who helped discover that DNA is a double helix by taking an x-ray image of it.

Rosalind Franklin

300
What is the proper name and purpose of mRNA in gene expression.
Messenger RNA is the "disposible" copy of the gene that leave the nucleus and carried the genetic code to the cytoplasm. It contains 3 base long codons that get translated into amino acids when they match up with anticodons.
400

List the stages of cell cycle in order. Be as detailed as possible.

Interphase (G1/S/G2) - prophase - metaphase - anaphase - telophase - cytokinesis - daughter cells back to interphase.

400

The phase of cell division when the nuclear membrane disappears.

What is prophase?

400

What is one difference between the location of DNA in prokaryotes and eukaryotes?

In eukaryotes, DNA is contained in the nucleus.

400
Give the base pairing rules discovered by Erwin Chargaff.
A to T and G to C.
400
What is the proper name and purpose of tRNA in gene expression.
Like minions, the transfer RNA carries amino acids to the growing protein. Each tRNA has an anticodon that matches with codons.
500
The type of cell division which creates exact copies of the previous cell for growth, healing, and asexual reproduction.
What is mitosis.
500

The stage of the cell cycle in which the cell spends the most time.

What is interphase.

500

The number of PAIR of chromosomes a typical human has.

What is 23?

500

Name one important characteristic of scientific investigations.

Answers may vary.

500
What is the proper name and purpose of rRNA in gene expression.
Ribosomes (ribsozymes) provide the site in the cytoplasm where the other types of RNA come together and build a polypeptide.
