Insertion and deletion mutations are said to cause shifts in the reading gram of the mRNA. Substitution mutations do not cause t
PSYCHO15rus [73]

Explanation:

A frameshift mutation  is an insertion or deletion in a sequence of DNA which disrupts the way the code is read. It occurs when the codons undergo a disruption through the deletion or insertion of one or multiple nucleotides (given that the number removed or added are not multiples of 3) - this alters the open reading frame; the amino acids produced through translation simply occur in a different sequence.

Further Explanation:

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

  • somatic: these only occur within certain cells, and arise from environmental factors such as UV light
  • hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

DNA, the genetic material of living organisms, is damaged by light in the
insens350 [35]

Answer:

The correct option is <em>B) ultraviolet region, especially below a wavelength of 320 nm.</em>

Explanation:

Ultraviolet light carries an enormous amount of energy in it. It is invisible to the human eye. When UV light with enormous energy and wavelength lesser than 320nm, hits the DNA, it causes changes in the structure of the DNA. Mostly, it affects the thymine nitrogenous base regions and forms pyrimidine dimers. The structure of the DNA changes on all the sites where dimers form and hence, they cannot be properly transcribed.
