The damage made by ionising radiation to DNA can be caused in one of two ways - one of which is a direct effect. What does direct effect refer to?Group of answer choicesThe radiation causes damage to molecules in the cell which then directly 'attack' and damgage the DNA.The radiation directly damages proteins that are coded for by DNAThe radiation interacts directly with the DNA to cause damageThe radiation directly damages amino acids.

With specific consideration of biology, what is it about ionising radiation that most makes it hazardous to life?Group of answer choicesIonising radiation interupts digestionIonising radiation leads to hair lossIonising radiation can directly induce cardiac arrestIonising radiation has the ability to cause damage to DNA

The main damaging effect of UV radiation on DNA is:Select one:a. Dehydrationb. Depurinationc. Formation of thymine dimersd. Single-stranded breaks

Radiation can be classified as either ionising or non-ionising radiation. Ionising radiation is the radiation that causes biological damage. What is the attribute of the radiation that defines whether it is ionising or not?Group of answer choicesThe ability to remove electrons from atomsWhether the radiation is as a particle or a waveThe length of exposure to the radiationThe intensity of the radiation

How does nuclear radiation cause illness?Multiple choice question.by introducing infectionby damaging large biological moleculesby destroying the immune systemby making tissues radioactive

The biological effects of radiation can be classified as and (genetic) effects. Somatic effects are the result of of the body tissues. The major feature of effects is that they are restricted to the irradiated, that is, they are not passed on to future generations. Examples of somatic effects are radiation-induced or radiation cataracts. effects are caused by irradiation of the and may be passed on to an individual's offspring. The effects do not appear in the person receiving the exposure but in their as they are caused by damage to the DNA of the sperm or . Examples of hereditary effects are and mental retardation.
