Week 4: Mitosis & Meiosis

99% of our cells undergo Mitosis....cell division to replace and grow cells identical cells (diploid cells)

1% of our cells undergo Meiosis....cell division to create sex cells (haploid cells)

Mitosis produces 2 daughter cells.

Meiosis produces 4 daughter cells.

To understand these two processes, undertake the nearpod presentation....firstly, download nearpod onto your device or open www.nearpod.com

What do these letters above stand for????

Task: Create a Venn Diagram of Mitosis and Meiosis


Using the prompts below and the assessment rubric above, create a Venn Diagram to show your understanding of the two cell division processes of Mitosis and Meiosis.

Emerging makes  4 cells makes 2 cells creates sex cells creates identical cells cells divide

Developing daughter cell has half the number of chromosomes daughter cell has the same number of chromosomes begins with a parent cell

Core produces daughter cells (identical/different) to parent cell (2/4) daughter cells happens in (germ/somatic) cells chromosome number (halves/remains the same) (1/ 2) times through nuclear division

PROTEIN (amino acid chain)SYNTHESIS (Formation of a whole)

Last week we realised that DNA contains the unique genetic information for an organism. 

This unique information is stored as genes that are contained within a chromotid (single chromosome).

So for each gene, a unique set of instructions are contained.

The gene contains the instructions for making a specific protein.

To make a protein, two processes occur:

1. Transcription of the DNA strand to create an mRNA strand (unzip and copy)
2. Translation of the mRNA strand to create a protein (read and form)




Watch the following video and notes have been included underneath it.

Video: Protein synthesis

Transcription - like steps of a recipe being given and organised into the correct order

RNA Polymerase attaches to the DNA and moves along to unzip the DNA
free bases attach to the exposed DNA nucleotides to form an mRNA
mRNA moves out of the nucleus and into the cytoplasm

Translation - like reading the recipe to create a meal

Ribosomes bind to the mRNA
Ribosome reads a codon (3 bases) at a time and attracts the specific tRNA
The tRNA bonds to the mRNA and delivers a specific amino acid
The amino acid bonds to a growing chain of amino acids
As the amino acid bonds to the chain, the tRNA detaches from the mRNA and floats back into the cytoplasm.

Once the last amino acid is added, it detaches from the ribosome and folds to form the protein.

Awesomely clever explanation!!!!!
