DNA
a molecular blueprint for a living thing
What does the nucleus contain?
DNA
What is the fundamental unit of a molecule?
an atom
Give an example of something denser than water.
rock, metal, honey, etc
What does DNA stand for?
deoxyribonucleic acid
What is the 'powerhouse of the cell'?
the mitochondria
What are molecules formed by?
two or more atoms
it has a higher mass per unit volume, with heavy sugar molecules that are packed tightly together
What does a ribosome do?
What is a compound?
different types of atoms bound together
Define density
mass per unit volume; how packed a material is
What is DNA made of?
nucleotides
What is ATP?
energy
State the composition of water
H2O
Explain the difference between mass and density
Mass is the total amount of matter in an object (measured in grams or kg), while density is how tightly that matter is packed into a specific space
transcription copies DNA into mRNA.
translation decodes mRNA to assemble amino acids into proteins.
Describe one of the steps of the cell cycle: Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
Interphase: The cell prepares for division by growing and replicating its DNA
Prophase: Chromosomes condense, the nuclear envelope breaks down, and the spindle apparatus begins to form.
Metaphase: Chromosomes align along the center of the cell (metaphase plate).
Anaphase: Sister chromatids separate and move to opposite poles of the cell.
Telophase: Chromosomes arrive at opposite poles, new nuclei form, and the chromosomes begin to decondense.
Cytokinesis: The cytoplasm divides, creating two genetically identical daughter cells.
What does polyatomic mean?
the combination of 3+ atoms
