HSC Biology

Polypeptide synthesis

the biological process where living cells make proteins based on instructions stored in the DNA

Recombinant DNA

enables individual fragments of DNA to be inserted into vector DNA molecules such as plasmids and divides in bacteria

Non dysfunction

Chromosomal mutation due to incomplete splitting of a chromosome leading to an extra/missing chromosome causing down syndrome

What is translocation

chromosomal mutation where a segment moves which can activate/inactivate genes creating leukaemia

What is inversion

a chromosomal mutation where a segments reversed which can disrupt genes creating haemophilia

What is duplication

A chromosomal mutation where a segments reversed which is repeated creating extra gene copies like in Charit Marie Tooth disease

What is deletion

A chromosomal mutation where a segments lost effecting many genes creating Cri du chat syndrome
