Textbook Question
Chapter 9.6, Problem 1HYEW
The saliva of dogs, like the saliva of most mammals (including humans), contains enzymes, antibacterial compounds, and growth factors. When a dog licks a wound, it not only cleans out some of the dirt and kills some of the bacteria that may have entered, but also leaves growth factors behind. The growth factors speed up the synthesis of cyclins, thereby stimulating the division of cells that regenerate the skin, helping to heal the wound more rapidly.

Release of lysosomal enzymes from white blood cells during a local immune attack can contribute to the symptoms of inflammation. Suppose to alleviate inflammation, you develop a drug that destroys all lysosomes. Would this drug have negative side effects? Why or why not? Answer this question in 1-2 sentences.
One important biological effect of a large dose of ionizing radiation is to halt cell division. What might be the effects of such a mutation if the cell is not irradiated?
Why is a rapidly growing tissue, such as the root tip of a plant, a good model for studying the effects of a drug on cell division?

- One important biological effect of a large dose of ionizing radiation is to halt cell division. How does this occur?arrow_forwardWhich of the following is the most likely effect of a mutation in the gene coding for a DNA repair enzyme? a.The mutated gene will not be transcribed because RNA polymerase cannot transcribe mutated DNA. b.Mutations will accumulate more quickly because the cell will not be able to fix errors in replication. c.The cell will immediately undergo apoptosis so that mutated DNA is not replicated in future rounds of cell division. d.The cell containing the mutation will divide more frequently because the cell cycle checkpoints will not function properly.arrow_forwardThe process by which messenger RNA codes for the synthesis of a specific protein is called: a) replication b) transcription c) translation d) gene regulation Which statement is true about prokaryotes? A) they have no chromosomes b) they have chromosomes, but they are not membrane bound c) they have membrane bound chromosomes d) their chromosomes are made of RNA rather than DNA In a eukaryotic cell, most ATP is made in which location? A) nucleus b) mitochondria C) cytoplasm d) golgi apparatusarrow_forward
- New treatments for several conditions are being developed using stem cells in medical waste, such as biopsy material, teeth, menstrual blood, umbilical cords, and fatty tissue removed in liposuction. For example, fat samples from injured horses are used to grow stem cells to treat tendon injuries. Explain how the two defining characteristics of stem cells enable them to be used to replace damaged or diseased tissue, so that the new tissue functions as opposed to forming a scar.arrow_forwardWhich of the following is not a characteristic of cancer cells? an increase in density dependent inhibition an increase in telomere length a decrease in DNA repair a decrease in cell adhesion molecules an increase in chromosome abnormalitiesarrow_forwardwhat type of cells possess unlimited proliferation potential and have the capacity to self renew, and can give rise to all cells within an organism?arrow_forward
- Which of the following best describes the difference between interphase and mitosis? a) During interphase, DNA has a loose structure that condenses during mitosis. b) During interphase, histones help compact DNA into chromosomes. And once mitosis starts, histones are destroyed. c) During interphase, DNA is tightly packed into chromosomes that uncoil once mitosis starts. d) During interphase, DNA is packed as chromosomes. And during mitosis, DNA is called chromatin. Please I need a surely answer and a quicker responsearrow_forwardWhy is it essential for a cell to repair mutations in its DNA? What happens to the cell if the mutations are too severe?arrow_forwardDescribe the specific molecular events that occur within a cell in response to growth factors outside of the cell.arrow_forward
- The term somatic cell refers to: A) normal body cells other than sperm and egg B) pluripotent cells C) most stem cells D) all of the above are somatic cellsarrow_forwardSuppose you discover a new gene called ABC that contributes to the efficiency of DNA damage repair. You have noticed that cells carrying mutations in this gene stop dividing and go into senescence. Do you think that mutations in this gene can cause cancer? Briefly explain your answer.arrow_forwardWhich types of cells are easier to replace, and thus can be found in places like our mouth and outer skin where we lose cells a lot?arrow_forward
