Answer:
The correct answer is - option D. nonsense and frameshift.
Explanation:
If there is a change in the sequence of DNA resulting in premature stop codon mRNA during transcription is known as a nonsense mutation and result in a non-functional protein.
a frame-shift mutation takes place when at least two nucleotides are altered and there are less chances to be changed by two others coding for the same nucleotide. It leads to a non-functional protein.
Answer:
They also occur in leaves and fruits and constitute the hard shell of nuts and the outer hard coat of many seeds. Sometimes known as stone cells, sclereids are also responsible for the gritty texture of pears and guavas

Conductive hearing loss is what may damage the ear drum and bones of the middle ear
C. be more susceptible to disease and famine.
this is because when a population experiences the bottleneck effect, the population is cut down significantly in size.
In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.
What causes a mutation?
Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.
