Analyze how mutations can be inherited or acquired.
Homework Answers
Mutations that are transmitted to offsprings through gametes are called as inherited mutations. A gene mutationnfor haemophilia or phenylketonuria are carried to next generation through gametes and such mutations are called as inherited mutations.
Mutations which an organisms acquires during its life time in response to environmental conditions are called as acquired mutations. Acquired mutations occur in somatic cells and are not transmitted to next generations. For example tanning of skin by UV rays is an acquired mutaion which is not transmittef to offsprings.

BRCAll is a tumor suppressor gene located on chromosome pair 13. Inherited mutations in BRCAII can predispose an individual to breast cancer. If Scarlet carries an inherited mutation for BRCAII and her husband Scott does not, what is the probability that their son inherited the mutated allele? O 0% o 25% O 50% O 75% O 100% Question 2 1 pts A plasmid SELECT ALL THAT APPLY. is a small circular piece of DNA independent of the chromosome is a...

If a person has inherited cancer mutations supposed to cause cancer, what can he/she do so that the they may not get any cancer? Or is it purely dependent on luck?

Cystic fibrosis (CF) is an inherited disorder caused by different types of mutations, many of which prevent ions from moving across cell membranes. Normally there are channel proteins that allow passage of the ions, but in patients with one kind of CF these proteins seem odd. Closer examination shows that these proteins display the correct amino acid sequence. However, they fail to do their job. A) Given that the primary structure of the protein is correct, what can you infer...

Temperature sensitive mutations are used to analyze biochemical pathways. A variety of mutations affecting DNA replication have been isolated in E. coli. What would you predict to see in the DNA after a mutation in each of the following occurred? (Answer each letter separately) (a) DNA ligase (b) DNA polymerase I (c) DNA polymerase III (d) Primase (e) Initiator Protein

Which of the following statements about mutations is/are incorrect? Choose all that apply. O Mutations in RNA during transcription are not inherited by daughter cells over multiple generations. O Mutations arise from sources other than just mistakes made during DNA replication. O Germ-line mutations can be passed down to offspring. O DNA replication machinery generates errors at a lower rate than RNA transcription machinery. O Mistakes in DNA replication do not lead to heritable mutations. Somatic mutations are often passed...

Question 9 1 pts Why are inherited forms of cancer autosomal dominant but not fully penetrant? 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...
