Cell division Flashcards
What is smallest unit of life
Cell
What is the biggest organelle of a eukaryotic cell?
A nucleus
What is found in the nucleus?
DNA
What is DNA and what does it stand for?
DNA contains genetic material and it stands for DEOXY RIBO NUCLEIC ACID
What does DNA look like inside a nucleus?
DNA looks like a double stranded of ladder and jumble up like a ball of yarn
What is genetic material
Genetic material are genes or traits that can be passed on from parents to offspring
How does DNA grow and develop and reproduce?
DNA reproduce through stages called INTERPHASE ABD MITOSIS
What happens during INTERPHASE
Interphase is when DNA develops and goes through repication
What does REPLICATION mean?
Copy or duplicate
What happend during REPLICATION
DNA replicates itself and wrap up tightly and neatly into chromatid
What is a chromatid
A DNA that is neatly wrap up(TWO CHROMATIN/SINGULAR:Chromatids
What is Chromosomes
When DNA wraps around a protein, it is called a chromosome
How many chromosomes do human have?
Humans have 46 chromosome
How many chromosome does each parents pass on to their offspring?
23 chromosome from each parent
Each segment of DNA is known as what?
Gene
What does gene contain
Genetic traits
What happens during MITOSIS
During mitosis, chromosomes go through 5 phase
What are 5 phase of mitosis
Ph 1: Prohase-chromosome; Ph 2: metaphase; Ph 3: Anaphase; Ph 4: Telophase; Ph 5 cytokinesis
What happens during each phase
Phase 1: Prophase-chromosomes apper
What happens during each phase
Phase 2: Metaphase-chromosome line up
What happens during each phase
Phase 3: Anaphase-chromosome separate
What happens during each phase
Phase 4: Telophase-chromosome pinch
What happens during each phase
Phase 5: cytokinesis- two new daughter cell form
How many chromosomes do human sex cells have
23 Chromosome in each sex cell(egg or sperm)
