Question

Quizplus · Accepted Answer

Apoptosis is the process of programmed cell death, also known as cell suicide.

Answer: A
 The genome refers to the complete set of genetic material (DNA or RNA) present in an organism or cell.

Answer: B
 Millirem is a unit of measurement used to quantify ionizing radiation, such as that from x-rays or nuclear reactions.

Answer: D
 Histones are proteins that help package DNA into a compact structure called chromatin, which allows for the efficient storage and expression of genetic information.

Answer: E
 Free radicals are highly reactive molecules that can cause damage to cellular structures, such as DNA, lipids, and proteins.

Answer: F
 Imprinting refers to a process in which genes are marked or modified in a way that affects their expression, often based on their maternal or paternal origin.

Answer: G
 Proofreading is the process by which enzymes correct errors that occur during DNA replication, helping to maintain the accuracy of the genetic code.

Answer: H
 Mutation refers to a change in the DNA sequence of a gene or genome, which can have a variety of effects on the resulting protein or phenotype.

Answer: I
 Methylation is a chemical modification that can alter gene expression without changing the underlying DNA sequence, often by silencing or inhibiting transcription of the affected gene.

Answer: J
 Frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame of the gene and potentially producing a completely different protein sequence.

Answer: K
 Senescence refers to a gradual decline in cellular function and viability, often associated with aging or exposure to toxins or stressors.
