example of a macromolecule‚ i.e. a large molecule with a special shape‚ which is built up from many smaller parts called sub-units . If you could magnify part of a nucleus‚ you would see the DNA molecule looking like a twisted rope ladder - a double helix. The two strands forming the sides of the ladder give it a strong yet flexible structure‚ which does not vary along its length. Stretched between these are the "rungs" of the ladder‚ the parts of the DNA molecule which vary‚ and so the differences

Investigating arteries and veins Methodology 1. Suspend a ring of artery from a hook on a clamp stand. 2. Use a metre rule to record the length of the ring once the mass carrier has been attached to the free end of the ring. 3. Attach a 10 g mass and record the length of the ring after the mass is added. 4. Remove the mass and record the length of the ring. 5. Repeat steps 2 and 3 using 20‚ 30‚ 40 and 50 g masses. Record the length with and without the masses each time. When comparing

adhesives generally can be well described by understanding their primary and secondary structures. However‚ soy proteins also have tertiary and quaternary structures. Their polypeptide backbone not only influences the secondary structures of crystalline α-helix and ß-sheet regions (which are distinct protein structural configurations)‚ but also influences the specific folding that forms the tertiary structures. Understanding how conditions alter these tertiary structures is an active research area for fields
