Dorsiflexion
Inversion
Plantarflexion
Pronation
Which of these is more proximal to the elbow: hand or head?

Intramembranous
Polyploidy
Totipotent
In endochondral ossification what does the bone replace?

Is Down’s syndrome an example if a aneuploidy or polyploidy?
Aneuoploidy
Polyploidy
What is an oocyte?
Egg cell undergoing meiosis to form an ovum
An egg undergoing meiosis to form a zygote
Define "Karyotype"
A heterozygous phenotype
A recessive gene
All of the alleles on a particular chromosome
An ordered representation of all 46 chromosomes
What is the role of topoisomerase in DNA replication?
It seperates the strands of DNA
It binds to the lagging strand to initiate transcription
It prevents the DNA helix from supercoiling ahead of the replication fork
It binds complimentary nucleotides to form a strand of mRNA
What is an Okazaki fragment?
A short section of DNA formed from discontinuous DNA replication on the lagging strand
Repetetive regions that form the very end of the lagging strand
What is the 2nd law of thermodynamics?
A system cannot function without organisation
The energy within a system cannot be lost or destroyed, only transferred
A system tends to disorder
A system will always reach equilibrium
In which direction does DNA helicase work?
Along the lagging strand in the 5' to 3' direction
Along the lagging strand in the 3' to 5' direction
Synthesis of complex molecules from simpler molecules is known as:
Catabolism
Anabolism
Why does the DNA strand get shorter during replication?
There are insufficient nucleotides to continue the strand
There is no neighboring Okazaki fragment to provide the needed hydroxyl, leaving a single-stranded overhang
Enzymes begin to break down the DNA strand to prevent unnecessary replication
Environmental factors can influence the length of the DNA strand
Where do you find proteoglycans?
Connective tissue
Synovial fluid
Bone marrow
Blood stream
Acute cellular injury resulting from exposure to noxious stimuli is known as:
Anoikis
Autophagy
Necrosis
Apoptosis
The line in a long bone that demonstrates the growth is known as:
Epiphysial line
Diaphysial line
Metaphysial Line
What are the 3 laws of inheritance?
Segregation, Independent Assortment and Dominanceand
Mendelian, Hierarchical and Hybrid
Single, Multi and Multi-Path
A joint in a fixed in position is known as:
Synarthrosis
Amphiarthrosis
Diarthrosis
