The organelle found only in eukaryotic cells is known as the “control center” of the cell
A segment that is the building block of DNA that is composed of a sugar, a phosphate, and a nitrogenous base is called…
A nucleotide
The phase of the cell cycle that occurs before cell division
What is Interphase
The number of rounds of division in meiosis
What is 2
The type of cell division that happens after gametes (sperm & egg) fuse to create a zygote
What is Mitosis
An organelle found in both eukaryotic and prokaryotic cells is responsible for making proteins
What are ribosomes
The four nitrogen bases found in DNA? (Full names for full points)
What are: Adenine, Thymine, Guanine, and Cytosine
The four stages of mitosis in order
What are Prophase, Metaphase, Anaphase, Telophase
The cells have a full set of chromosomes (aka 2n)
What is Diploid
The type of bond that holds nitrogen bases together in the middle of the DNA molecule
What are Hydrogen Bonds
One similarity and one difference between plant and animal cells
What is ...[any of the following]:
Similarities: both eukaryotic cells with organelles like the nucleus, cell membrane, mitochondria, etc.
Differences: Plant cells have a central vacuole, cell wall, and chloroplasts
The strands run in opposite directions in order to fit together properly
“Antiparallel” DNA strands or “complementary” strands
Division of the nucleus vs division of the rest of the cell
What is Mitosis vs Cytokinesis
The products of Meiosis
What are:
4 cells (gametes aka sperm or eggs)
that are unique (different from each other and their parent cells)
and have half the number of chromosomes
The diploid (2n) and haploid (n) number of chromosomes that humans have
What are:
Diploid (2n) = 46
Haploid (n) = 23
The first immortal cell line (continues dividing outside the human body)
What are HeLa Cells
When DNA is wrapped around proteins then compacted together it is called _________ then it is further condensed into ___________
What are chromatin and chromosomes
The products of Mitosis
What are two daughter cells that are identical to each other and the parent
The process where homologous chromosomes swap segments of DNA in a particular stage of meiosis
What is crossing over during Prophase 1
After fertilization a human zygote has a full set of 46 chromosomes instead of a double set of 92 because…
What is because gametes (sperm and egg) are always haploid
