Diffraction occurs when a wave moves through an opening in a barrier. This causes the wave to change direction and spread out.
Waves can behave in three different ways depending on the obstacles they encounter. They can reflect, refract or diffract. In diffraction, waves such as sound, light or water either bend around small objects that obstruct their passage or spread out as they travel through a gap in the barrier.
The degree of diffraction forms a direct relationship with wavelength. It generally increases as wavelength increases. Conversely, the amount of bending lessens as wavelength decreases. However, if the opening of the barrier is smaller than the wavelength, the effect of diffraction is not easily observed. Hope this helps.

DNA Helicase - unwinds the double helix by disrupting H bonds that bind the nitrogenous bases
Single-stranded binding proteins - prevent the separated DNA strands from re-attaching
RNA Primer - made up of multiple nitrogenous bases which are attached to the template strand and initiate the building of a new complementary strand i.e replication
Primase - builds RNA primers
DNA Polymerase I - removes RNA primers and replaces them with appropriate DNA nucleotides
DNA Polymerase III - creates complementary strands of DNA, attach to an RNA primer, and add nucleotides to the 3' end
DNA Ligase - joins Okazaki fragments together by phosphodiester bonds
DNA Gyrase - relieves tension produced when DNA double helix is unwound by helicase
Answer:
A tadpole is the larval stage in the life cycle of an amphibian. Where as a froglet is a semi metamorphosed Tadpole. A froglet is still in the process of becoming a frog, through tice the froglet will slowly metamorphoses futher to its adult and final stage.
