Genomic imprinting is the case where the expression of a gene is carried out by only one allele. In humans there are very less number of tumor supressor genes which are genomic imprinted because, the expression and function of the gene is restored by avoiding the imprinting, since these genes are crucial for the survival of the cells.
Add Answer to:
14. In humans, very few tumor supressor genes undergo genomic imprinting (that is, are expressed from...

12. Kevin is a male (XY) very short due to a condition known as de novo X-linked achondroplasia, which was caused by a denovo germline mutation in an X-linked gene. Did that mutation occur during spermatogenesis or oogenesis? (2 points) Do we expect that Kevin's daughter (XX) has achondroplasia - definitely, possibly or definitely not? Why? (2 points) 13. Consider the following pedigree: 167 8 9 10 Is this pedigree consistent with gray representing an autosomal recessive trait? If not,...

In mammalian cells, genes that are expressed in a particular
cell are reported to undergo replication during the first half of S
phase, and genes not expressed in that cell are replicated in the
latter half of S phase.

Humans have engaged in genetic manipulation for millennia, producing plant and animal varieties through selective breeding and hybridization that significantly modify genomes of organisms. Why do you think modern genetic engineering, which often entails introducing or modifying only one or a few genes, has met with so much opposition? Should some forms of genetic engineering be of greater concern than others? Explain. In your response provide a specific example from literature to support your stance.

4. Do you think it is possible for humans to undergo sympatric speciation? Explain. 5. Earth's different environments are constantly changing due to geologic and climatic processes. With this in mind, could an organism's vestigial structure(s) become useful again and eventually be required for survival? Explain Evolution Connection Typically speaking, in the human population, humans lack the ability to metabolize lactose. This condition is known as lactose intolerance. It is necessary for infants to digest lactose because that is their...

What were the technologies that had to exist for this technology to be developed? What technologies were developed to support? Who developed the technologies? Mouse pups with same-sex parents born in China using stem cells and gene editing Researchers at the Chinese Academy of Sciences were able to produce healthy mice with two mothers that went on to have normal offspring of their own. Mice from two dads were also born but only survived for a couple of days. The...

What genes (or kind of genes) will you focus on in your investigative research? Provide 2-3 reasons for your choice of these gene/s. Starting with the bone sample itself, what methods will you use to get DNA that you can sequence? Which “ingredients” in your lab reactions will determine which gene or genes are copied? How is it that these ingredients are able to target a specific gene? What method will you use to see if your efforts to copy...

All of the features below are features that characterize humans,
though very few of them are unique to humans. Rather, most of them
are present in our species because of our evolutionary history
(they were present in an ancestral species at some point in time,
and eventually passed on to us). For example, the bilateral
symmetry that characterizes the human body plan is a feature that
evolved in a primitive animal species that lived hundreds of
millions of years ago;...

1. the genes that seem to be the most necessary to maintain, since they are present in the smallest cellular organisms are a. cytoskeletal protein genes b, translation protein genes c. replication protein genes d. transcription protein genes e. DNA repair protein genes 2. Why do cellular organisms generally look very similar when early embryos but different from each other when mature? a. their DNAs have different chemistry b. their RNAs are different lengths c. what genes get turned on...

B. Albinism Most humans (and vertebrates, in general) are genetically "programmed" to produce a brown skin pigment known as melanin. Albinism, the inability to produce melanin, is inherited in humans as an autosomal recessive trait. An individual with genotype AA or Aa will have normally pigmented skin, whereas an individual with genotype aa will produce no melanin. The albino's skin is very pale white. The white color occurs because one or more steps in the biosynthetic pathway for melanin do...
