Level 1
Which Cells came first: Prokaryotic Cells or Eukaryotic Cells?
eukaryotes
Describe DNA Replication.
the process by which the genome's DNA is copied in cells.
Describe what DNA contains instructions for.
an organism to develop, survive and reproduce.
Identify 2 structures Prokaryotic Cells lack.
a nucleus and membrane-bound organelles.
What are molecular building blocks of cells?
amino acids, lipids, and nucleotides.
Once each Sister Chromatid pair has been separated during Anaphase, what is each Sister Chromatid considered to be?
Why must the Sister Chromatid pairs separate during Anaphase?
ensures that each daughter cell receives an identical set of chromosomes
Name the 2 Cell Cycle Phases.
interphase and the mitotic (M) phase.
What are the building blocks of cells quizlet?
What are the 4 biomolecules and their function?
carbohydrates, lipids, nucleic acids, and proteins.
Why must Cytokinesis occur following Mitosis?
to separate the cell in half and ensure that one nucleus ends up in each daughter cell.
Why are G1 and G2 known as "Gap Phases?"
They are a period when the cell is not dividing and is not going through mitosis.
How does the parent cell compare to the daughter cell?
each contain the same number of chromosomes as their parent cell.
Contrast Unicellular vs Multicellular Organisms.
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function.
How do Prokaryotic and Eukaryotic Cells compare in complexity?
eukaryotic cells are more than 100 to 10,000 times larger than prokaryotic cells and are much more complex.
Which phase does Crossing Over occur in during Meiosis I?
prophase I
In Metaphase, why are Spindle Fibers connected to the Sister Chromatids at the Centromere?
ensure that sister chromatid s will separ ate and go to different daughter cells when the cell divides.
How do diploid cells compare to parent cells?
The daughter cells resulting from mitosis are diploid and identical to the parent cell.
Which Organism types are Eukaryotic Cells found in?
all animals, plants, fungi, and protists, as well as most algae.
Where is the DNA located in Prokaryotic Cells vs Eukaryotic Cells?
Eukaryotic chromosomes are located within the nucleus, whereas prokaryotic chromosomes are located in the nucleoid.
Where does each Chromosome in a pair of Homologous Chromosomes come from?
one inherited from the mother and one from the father.
Describe what is occurring in the 2 phases of the Mitotic Phase.
a progressive phase, during which the chromosomes condensed and aligned at the center of the spindle, and a regressive phase, during which the sister chromatids separated.
How do the parent cells chromosomes compare to the daughter cells chromosomes?
Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes.
How many Chromosomes are in Human Diploid and Haploid Cells?
How many Chromosomes are in Human Diploid and Haploid Cells?
lets just say that if you were to bulk up and you consume all of the protein that your body needs to bulk up and you do intense weightlifting and do intense cardio so why aren't you bulking up?
doing intense cardio can actually decrease the rate of your muscles reproducing and bulking up.
