As more is learned about cancer, it has become clear that cancer, with few exceptions, ________. Group of answer choices is only dependent on the inherited genetics is a result of genetics and environmental factors is 100% dependent on inherited genetics has no genetic basis

Answers

Answer 1

Answer: Is a result of genetics and environmental factors.

Explanation:

Cancer is the common name for a group of diseases in which there is a division of the body's cells, whose growth exceeds that of normal tissues and which persists in the same excessive manner. It can begin in a localized manner and spread to other surrounding tissues and its malignancy is very variable, according to the aggressiveness of its cells and other biological characteristics of each type of tumor. In general, the behavior of cancer cells is characterized by lacking the reproductive control required by their original function, acquiring the capacity to invade tissues (metastasis), spreading through the organism via the lymphatic or circulatory system, and causing the growth of new tumors in other parts of the body.

A gene is a hereditary unit composed of DNA that carries the instructions for producing proteins, which do much of the work in our cells. Certain genetic alterations can cause cells to evade growth controls and become cancerous cells. These changes can be inherited from our parents if the changes are present in the germ cells (eggs and sperm) and they are called germline changes. In addition, cancer-causing genetic changes can also be acquired during a person's lifetime (somatic or acquired changes), as a result of DNA errors that occur when cells divide either spontaneously or by exposure to carcinogenic substances that damage DNA (environmental factors), such as certain chemicals in tobacco smoke, or radiation, such as ultraviolet rays from the sun. These substances damage DNA, acting as mutagens.

Sometimes, the changes are not in the DNA sequence. For example, the epigenetic modifications are the presence of chemical marks in DNA which can determine if the gene is expressed. This means, whether and how much messenger RNA is produced, because the messenger RNA is translated into proteins.

So, cancer cells have genetic changes compared to normal cells. These changes are due to mutations that can be inherited, acquired spontaneously during life, or acquired due to environmental factors such as sun exposure, smoking, and other factors. In addition, the fact that a person has the cancer-related mutation does not necessarily mean that he or she will develop the disease during his or her lifetime. In some cases, even if they have this genetic vulnerability, they remain healthy, because cancer is a multifactorial disease that depends on many factors, such as the immune system, nutrition and certainly many others currently unknown to medicine.

Approximately how many mutations occur naturally in DNA per 10,000 bases?
A. 2
B. 2000
C. 200
D. 20

Answers

Explanation:

Modern methods indicate that the mutation rate is roughly one to two mutation per 10,000 genes per generation.

In human cells, approximately TWO (2) MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).

The mutation rate (u) refers to the occurrence of new mutations in a given nucleotide sequence over time.

In human cells, the mutation rate is approximately 10⁻⁴ per generation.

Therefore, in a DNA sequence that has 10,000 base pairs of length, this value is equal to 2 mutations per generation (u = 2 / 10,000 = 10⁻⁴).  

In conclusion, approximately 2 MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).

Group of answer choices None of the above options is correct produced by PR agencies and companies for use in TV newscasts aired by TV stations as part of their requirement to serve the public interest public service announcements (PSAs) eagerly accepted by TV news departments, especially in large markets The fields of antebellum (pre-Civil War) political history and womens history use separate sources and focus on separate issues. Political historians, examining sources such as voting records, newspapers, and politicians writings, focus on the emergence in the 1840s of a new "American political nation," and since women were neither voters nor politicians, they receive little discussion. Womens historians, meanwhile, have shown little interest in the subject of party politics, instead drawing on personal papers, legal records such as wills, and records of female associations to illuminate womens domestic lives, their moral reform activities, and the emergence of the womans rights movement.However, most historians have underestimated the extent and significance of womens political allegiance in the antebellum period. For example, in the presidential election campaigns of the 1840s, the Virginia Whig party strove to win the allegiance of Virginias women by inviting them to rallies and speeches. According to Whig propaganda, women who turned out at the partys rallies gathered information that enabled them to mold party-loyal families, reminded men of moral values that transcended party loyalty, and conferred moral standing on the party. Virginia Democrats, in response, began to make similar appeals to women as well. By the mid-1850s the inclusion of women in the rituals of party politics had become commonplace and the ideology that justified such inclusion had been assimilated by the Democrats.The primary purpose of the passage as a whole is toA. examine the tactics of antebellum political parties with regard to womenB. trace the effect of politics on the emergence of the womans rights movementC. point out a deficiency in the study of a particular historical periodD. discuss the ideologies of opposing antebellum political partiesE. contrast the methodologies in two differing fields of historical inquiry Tm hai s c tng l 177.
