Week 2 - Protein Synthesis, Cell cycle, Mitosis + Meiosis

What is the information in DNA in the nucleues used to produce?

protein

transcription

• DNA molecule is unzipped

• mRNA molecule is created from the DNA template

Translation

• formation of a linear chain of amino acids

• uses trancribed information given by mRNA strand

• mRNA template is translated to synthesize protein

• happens in ribosome

Mitosis & Cytokineses

cell divides creating two daughter cells that enter interphase again

Mitosis (diploid)

• single cell divides into two

• PMAT (prophase, metaphase, anaphase, telophase)

Meiosis (haploid)

• makes gametes (sperm and egg cells)

Interphase

the stage of normal growth and development

G1

growth stage of interphase

S phase

stage of interphase where DNA replicates

G2

stage of interphase when cell prepares for division

Mitosis

cell phase in which the nucleus divides

Prophase

first stage of mitosis, the nuclear membrane disappears

Metaphase

second sgtage of mitosis, chromosomes align in the middle of the cell

Anaphase

third phase of mitosis, sister chromatids move to opposite ends of the cell

Telophase

fourth phase of mitosis, nuclear membrane and nucleolus repair

Cytokenisis

division of the cell cytoplasm
