Different cells in your body (like muscle cells and brain cells) look very different and do very different jobs in your body. Select all the true statements about these cells: The nuclei of muscle cells and brain cells contain identical chromosomes to each other. Muscle cells have different chromosomes than brain cells. Muscle cells and brain cells have the same genes on their chromosomes muscle cells and brain cells have different genes on their chromosomes Muscle and brain cells express (use) every gene found on their chromosomes Muscle cells and brain cells express (use) all the same genes as each other Muscle cells and brain cells express (use) different genes from each other tv MacBook Air 80 888 FB F7 F4 F3 & # $ % 9 5 6 8 3 4 P Y U E K F G C V command ...- R
The continuity of life depends on a cell cycle during which genetic information is passed from a parent cell to daughter cells. Because cell division plays several important roles in life, it is important that the cycle be regulated. Which of the following are reasons the cell cycle must be regulated? Select all that apply. The continuity of life depends on a cell cycle during which genetic information is passed from a parent cell to daughter cells. Because cell division plays several important roles in life, it is important that the cycle be regulated.Which of the following are reasons the cell cycle must be regulated? Select all that apply.[ ]To make sure cells only divide when conditions are favorable for growth and development of the organism[ ]To make sure daughter cells end up with the right number of chromosomes[ ]To make sure daughter cells are genetically different from the parent cell[ ]To allow cells to respond to cues from their internal state and from their environment.
In many organisms, the sex of the organism is determined by its genețic code. In most mammals, including humans, the sex of the organism is determined by genes that fall on specific chromosomes called the X and Y chromosomes. Most mammals have two sex chromosomes. A mammal cell with two X chromosomes is from a organism and a mammal cell with one X and one Y chromosome is from a organism. In humans, the SRY gene is responsible for in cells. This gene occurs on
You are studying a gene that makes a protein product that is important to vision. In which cell types might you expect this gene to be silenced? Choose all correct answers. Only choose "none" if the gene would not be silenced in any of these cell types. ✔none bone marrow cells of an adult cells in the retina of the eye of an adult Opluripotent cells in the developing embryo skin cells of an adult
Every cell contains all of the DNA for an organism. What controls when and how specific genes are expressed? Genes are not controlled, all genes are expressed all the time Gene expression is controlled by sequences in the DNA Gene expression is controlled by proteins Gene expression can be controlled by proteins and sequences in the DNA O 000
How does gene expression influence the behavior of cells that contain the same genome (genetic information)? In other words, why do cells that belong to the same multicellular organism have a different structure and function?
There are close to 200 different cell types in the human body. Why do they look and function differently from one another? O They each express a different set of genes O They each express all the same genes, but in a different order at different times O They each have slightly different genomes O They all express the same genes, but proteins that aren't needed in a particular cell type are degraded before they can function QUESTION 10 When you exercise, you typically start breathing harder. This is because: O You are switching from aerobic to anaerobic respiration O More oxygen is needed to meet the increased ATP demand O Carbon dioxide stores are quickly depleted during exercise Muscle cells can only use aerobic respiration
A controversial issue, closely related to cloning, that has caused a lot of debate is the use of embryonic stem cells. One possible application of these cells is that they may be able to supply replacement tissues to treat diseases such as Parkinson's disease, diabetes, paralysis due to spinal cord injuries, and other degenerative diseases. The word "embryonic", has caused fierce opposition to this type of research because embryos are destroyed when the stem cells are removed. Questions that have surfaced in this debate include: When a cell nucleus is transferred to another cell, have we created life? Does a stem cell have the same status as a human? What should be done with the embryos that are leftover at in vitro fertilization (IVF), clinics? Advocates argue that the medical benefits of stem cell research would be enormous. Opponents argue that life begins at conception and thus this type of research is abortion. Based on what you have read, explain why you are for or against stem…
I am confused about how stem cell transplants works. If you put a semi differentiated tadpole nucleus in a denucleated egg cell, it’ll develop into a fully formed tadpole, but if you put a fully differentiated tadpole nucleus, it won’t (because the genes have already been expressed in a way where the cytoplasmic determinants cannot operate to the fullest). Then how come in stem cell transplants, you use adult nucleuses that are already developed and transplant them into the denucleated egg cells?
ou now have an understanding of Genomes, DNA Replication, Transcription, Translation, and Regulation of Genes. How would you reprogram skin cells to create cells which look and behave like brain cells (neurons)? What would you change/modify to reprogram a skin cell to a neuron? How would you introduce the change/modification into the skin cells to transform them into neurons?
All the cells of one organisms share the genome. However, during development, some cells develop into skin cells while others develop into muscle cells. How can the same genetic instructions result in two different cell types in the same organism? Thoroughly explain your answer.
