The precursor RNA for the siRNA pathway is a longer dsRNA. As a consequence of this different initial substrate, Drosha is not needed for the generation of siRNAs. Cleavage by Dicer is still required, however, and again generates a suitable 21- to 22-nucleotide RNA for incorporation into RISC.

#Unit 8. Inheritance Biology

Autosomal dominant 

Traits appear in both sexes with equal frequency.

Both sexes are capable of transmitting these traits to their offspring.

An affected person has an affected parent (unless the person carries new mutations). 

The trait does not skip generations.

Unaffected people do not transmit the trait. 

Example- familial hypercholesterolemia, Huntington disease, Neurofibromatosis

Electron affinity: The enthalpy change that results from adding an electron to a gaseous atom.

Electron affinity is becoming less negative (less exothermic) and less likely to gain an electron.
