The Ames test can help to identify carcinogens by their activity as mutagens. Which options below are mechanisms by which carcinogens cause mutations in DNA.
A. by binding to DNA and directly disrupting base pairing.
B. by hybridizing punnet squares
C. by generating cross-links between DNA strands.
D. by causing double strand breaks (DSBs)
Question
The carcinogens are the substance that cause cancer in the person. The mechanism through which they cause cancer by causing double stranded breaks that generate ionized ion. Hence option D is correct.

QUESTION 3 The codon S-AUG-3' on an mRNA encodes the amino acid methionine. What is the corresponding anticodon found on the methionine charged tRNA? 3-UAC-5 5-UAC-3 o 3-GUA-5 5'-ATG-3 QUESTION 4 Match each cause of DNA damage with the mechanism by which it can lead to mutations. Topoisomerase is unable to function properly, and when it makes A cuts in the DNA strands these are not always repaired. This leads to a loss of nucleotides and potential frameshift mutations. In...
The following statements apply to concepts and material discussed in Chapter 15; identify which statement is TRUE. Answers: A common ancestor of two species on evolutionary trees can be found at the point where the two branches meet. Humans evolved from Neanderthals about 50,000 years ago. Mitochondrial DNA is not particularly useful when trying to determine the movement pattern of humans historically across the globe. Scientists can estimate when species diverged from a common ancestor by comparing their Karyotypes. We...
can help me writing a summary please Chromosomal Aberrations and Human Disorders In addition to mutations that alter the information content of a single gene, chromosomes may be subjected to more extensive alterations that occur most commonly during cell division. Pieces of a chromosome may be lost or segments may be exchanged between different chromosomes. Because these chromosomal aberrations follow chromosomal breakage, their incidence is increased by exposure to agents that damage DNA, such as viral infection, X‐rays, or reactive...
