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

Worksheet 2
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.
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.
