Cancer can be described as ["a genetic", "an infectious"] disease which results from ["mutations in multiple different genes", "a single gene mutation"] that occur primarily in ["somatic", "germ"] cells
Homework Answers
1. A genetic
Cancer is a genetic disease because it is caused by changes in the genes. Mutations led to these changes. It is not an infectious disease because it does not transfer from one person to another.
2. Mutations in multiple different genes
Generally a single mutation in a gene can be corrected. Cancer
results when mutation occurs in different genes. That’s why Cancer
is defined as group of diseases.
3. Somatic
Most cancers results from mutations in somatic cells.
Somatic mutations are the mutations which can occur in all somatic
cells of our body and can be only passed to their daughter
cells.

please choose correct options. options are in [] and are bold. there are 2 parts. in a population, there is a single-gene, autosomal recessive disease with 2 alleles, D and d. The disease is deadly and kills patients at an early age. Over time, natural selection will ["tend to reduce", "tend to increase", "have no effect on"] the frequency of the d allele in the gene pool. But as this occurs, a ["smaller", "larger",...

Even if the mutation is inherited, a loss-of-funciton mutation ipmscting one allele is not expressed The inherited allele is dominant at the cellular level, but might not be expressed depending on genetic background Most inherited mutations are recessive at the cellular level Sporadic, but not inherited forms of cancer forms of cancer are caused by somatic mutation Question 10 1 pts Select true statements...

Consider a spontaneous mutation in the gene HER2, a tumor suppressor involved in cell cycle control Mutations happen at a rate of about 1 error per 109 bases per generation. A spontaneous deleterious mutation must occur in HER2 specifically, and not in another gene. The likelihood that a spontaneous mutation is deleterious and could lead to cancer depends on the number of mutable bases in HER2, the fraction of bases that will affect the function of HER2, and that both...

please answer all the question to get a like. Part III Dr. Hernandez sits down with Ann and her partner. The doctor is sorry to report that Ann has breast cancer; however, because it was caught early and responds to estrogen and progesterone, the prognosis is good. At this point it looks like the cancer is stage 1. However, as Ann is young, the doctor wants to perform a couple of tests. The first test is a genetic sequencing test...

Cancers arise from a multistep process that involves the interplay of multiple changes, or mutations, in several different genes, in combination with environmental factors such as diet or lifestyle. Based on the relationship between genetic alterations and cancer development, please answer the following prompts: If mutated, what gene would lead to the proliferation of cells that survive when they should not? If mutated, what gene would lead to further mutations in other genes? Identify and describe each stage of multistage...

6. How can a missense mutation-such as in sickle cell disease-result in a protein that has an abnormal structure? Some of these mutations are lethal or cause serious disease, such as cystic fibrosis and sickle cell disease. Many of these point mutations that cause genetic disorders occur as a result of errors in DNA replication or crossing over. 7. What will be the consequence if a single base is deleted from the coding region of a gene?
