The skin is an organ that turns over rapidly: dead cells are constantly being shed and replaced by new ones. Which of these factors help ensure that the new cells have the same identity as the old cells? O When cells differentiate they only maintain the DNA of lineage-specific genes, so these genes are transmitted to the daughter cells Cells in all tissues have the same epigenetic marks Epigenetic marks are completely erased when the parent cell undergoes mitosis but are rapidly re-established in the daughter cells Epigenetic marks are maintained through mitosis so daughter cells express the same genes as the narental cells

A couple well informed about the epigenetic effects of nutritionand dietary supplements such as choline and folatedecided to take supplements before trying to get pregnant.Their first child was born with hair and eye colors very differentfrom the parents and has been consistently praised by teachersfor learning ability and memory. The couple attributes these characteristicsto their intake of epigenetic supplements. Now theywish to have another child and have informed their physician thatthey intend to greatly increase the amount of supplements theytake to increase the epigenetic effects in their child. The physiciancautioned them that studies available in human trials showno effect of choline on learning and that excess intake of folateduring pregnancy may be associated with an increased risk ofautism spectrum disorder in the child. The couple is convincedthat these studies are not conclusive, and while more research isneeded, they intend to pursue their plan of increasing their…
Do cells which lack normal cell cycle control (cancerous cells) exhibit karyotypes that look physically different than cells with normal cell cycle control?
Normally functioning cell cycle regulators are molecular signals that do all of the following EXCEPT: Inhibit progression through the cell cycle Stimulate progression through the cell cycle Instruct cells to progress from M phase directly to G2 phase during the cell cycle Instruct cells to initiate programmed cell death during development Instruct cells to differentiate during development
. Neurofibromas are tumors of the skin that can arisewhen a skin cell that is originally NF1+/ NF1− losesthe NF1+ allele. This wild-type allele encodes a functional protein (called a tumor suppressor), while theNF1− allele encodes a nonfunctional protein.A patient of genotype NF1+ / NF1− has 20 independent tumors in different areas of the skin. Samplesare taken of normal, noncancerous cells from thispatient, as well as of cells from each of the 20 tumors.Extracts of these samples are analyzed by a techniquecalled gel electrophoresis that can detect variantforms of four different proteins (A, B, C, and D) allencoded by genes that lie on the same autosome asNF1. Each protein has a slow (S) and a fast (F) formthat are encoded by different alleles (for example, ASand AF). In the extract of normal tissue, slow and fastvariants of all four proteins are found. In the extractsof the tumors, 12 had only the fast variants of proteinsA and D but both the fast and slow variants of proteins B and…

Your friend sends you two cancerous cel| lines to examine and determine possible mutations. The results are shown below: Cell Line Mutation WT none (wild type DNA) 1 a deletion at the same region on both copies of chromosome 4 2 a point mutation in a gene on only one copy of chromosome 7 You learn that cell line 2 is a breast cancer cell line that expresses a mutant version of a receptor protein called KIT. Based on this data, which of the following is true ? Select all that apply Activation of KIT promotes progression through the cell cycle Activation of KIT releases an inhibition of a cyclin Activation of KIT causes cells to enter GO O Activation of KIT promotes cells to undergo apoptosis
A protein called p53 is another protein involved in controlling cell division. The protein p53 makes sure that if cells aren't functioning correctly, they don't divide anymore. Some people have damage to their p53 DNA and the protein isn't made correctly anymore. What might be a consequence if a person couldn't make the protein p53? A - Their cells would no longer use oxygen to make energy B - Their cells would no longer divide C - Their cells would make too much carbon dioxide D - Their cells could divide out of control
p53 gene, as is the Rb gene, is a tumor suppressor gene. p53 protein binds to DNA leading to the simulation of p21 that work together with cdk2. When p21 is defective and cannot joined to cdk2 the cell cannot pass through to the next stage of cell division. Mutated p53 cannot bind to DNA in an effective way, and therefore the p21 protein is not available to act as the 'stop signal' for cell division. Thus cells divide uncontrollably, and form tumors. Hi, can you please elaborate on this: based on the info above, what is the relationship between genetics and environment in the development of these type of cancer. Which factor (genetics or environment) is playing a larger role in the generation of these types of cancers?
Which of the foll owing characteristi cs about homologous chromosomes in somatic cells is false? O They contain the same allel es. )They are of similar size. They contain the same genes. OThey have similar banding patterns when dyed. Genes are in the same location.on each chromosome.
Most forms of cancer are caused by environmental agents that produce mutations in somatic cells. Is an individual with cancer considered a genetic mosaic? Explain why or why not.
