At one time, organisms were only the size of one cell; they divided and developed into the individuals like humans that are made of trillions of cells. Every cell in the human body received a copy of an original nucleus with the exact same genes and chromosomes. All of the cells in the body evolved from a single cell. Mito
I am working on a genetics assignment and am completely stumped on this problem. I have looked at it for hours and cannot figure it out. The biggest problem I am running into what kind of mutagen could induce these specific changes. I've tried various ways of frame shifting, but nothing seems to be working here. Please help!

The diagram provided takes the student through each step of the process including: 1. DNA transcription 2. mRNA translation 3. The genetic code.
Punnett squares for monohybrid crosses are relatively straightforward until we begin to consider x-linked (sex-linked) traits. This looks at the basics of punnet squares and notation that can help you to solve them and keep track of what is going on. Three problems are addressed here. First, we look at the case of a straightforw
How will toxicogenomics, which is the analysis of the effects of toxic chemicals on genes (for example, gene mutations or changes in gene expression), be influential in the next decade? Please provide details and specific examples.
I am doing a research paper and I need opinions. The question: "is it appropriate to use emerging synthetic genomic engineering technology to build new forms of "life"? I would appreciate pros and cons as part of my research. The explanation is given in 300 words.
One aspect of aging appears to be related to telomeres. Every time a chromosome is duplicated in the S Phase of interphase, the ends of the chromosome (i.e. telomeres) unravel. This sets a limit of around 50 cell divisions before the chromosome unraveling effects genes. Explain the significance of this.
1. What is the state of the DNA at the end of meiosis I? What about at the end of meiosis II? 2. Why are chromosomes important? 3. How are Meiosis I and Meiosis II different? 4. Name two ways meiosis contributes to genetic recombination. 5. Why do you use non-sister chromatids to demonstrate crossing over? 6. Why is it nec
Your colleague has an EST fragment from E. coli with the following sequence: AAGUCAUUAUUUUCG. Assuming this is the coding strand, can you help her to identify the most likely translation frame?
Can you provide an overview (abstract) of Avery, MacLeod and McCarty's important experiment demonstrating that DNA is the transforming principle. When I say "abstract", I mean a brief summary of the research, including details about how the experiment was carried out, and what the results were. Please also provide reference
DNase hyper sensitive sites are important for changing chromatin structure during transcriptional activation of genes. Use BOTH diagram & written explanation: Determine whether DNase (HSS) formation at specific sites in promoter regions is an important component of transcriptional activation of a gene you are studying duri
Discuss the three different types of gene mutations (base substitutions, insertion & deletion). Please describe in detail how insertion, deletion, and base substitution of nucleotides can have a significant impact on genes, and provide three specific examples (actual gene mutations, not chromosome mutations) of ways in whic
The coefficient for selection between Zid+ and Zid- in common garden experiment of an individual being treated with AZT is 0.036, indicating selection for Zid-. What are the relative fitnesses of Zid- and Zid+? Absolute fitness of Zid+ in AZT treated people is 1.040. What's the Absolute fitness for Zid-?
Please relate Mendel's Law of Segregation and Law of Independent Assortment to meiosis and please describe the stages of meiosis that demonstrate these laws.
Gene is a new staff-level auditor on the audit of CalPower, a publicly traded energy and utility company. On his first day, his senior informs him that the engagement team is scheduled to have lunch with the internal auditor to discuss ways to improve this year's audit. While Gene has heard a lot about internal auditing in school and has some friends who recently began working as internal auditors, he is unfamiliar with exactly what internal auditors do and how internal and external auditors can work together to improve the audit process. Gene decides to take a look at last year's internal audit report prepared by CalPower's internal auditors. He notices that the report includes a sentence that reads, "CalPower's Internal Audit group maintains a high level of independence from management." Because Gene is intimately familiar with the extensive independence requirements of his own firm, he cannot figure out how CalPower's internal audit group can possibly assert their own independence. What is meant by independence from management for internal auditors? 250-500 words

Researchers have long been asking the question of what causes addictive behavior and why some people feel compelled to keep abusing substances they know are harmful and detrimental to themselves. Growing evidence suggests both the biologic and genetic basis of addiction, which may explain this apparently self-destructive behavi
In this Nature journal article about the dog genome, how do I answer the following questions? What was the author's purpose? Why did the author decide to sequence the domestic dog's genome? What are 3 major conclusions that you learned from this paper? What future experiments did the authors propose, now that there is a d

See the attached file. Describe the E-value distribution are they small (close to zero) large (close to 1). Is the subject sequence from the top 2 BLAST hits from a genus and or a phylum that you would expect to be closely related to T. oceani?

Gregor Mendel discovered that tall was dominant and short recessive in pea plants. When he crossed two plants that were both heterozygous tall (Tt) he found a 3:1 ratio of tall to short (75% tall, 25% short) in the offspring leading him to conclude that in a monohybrid cross, the offspring would show a 3:1 ratio of dominant to
In couples where each person is heterozygous for the sickle-cell gene, there is a probability of 0.25 that any child of the couple will have the disease. A husband and wife, who are both heterozygous for the sickle-cell allele, are planning to have a family of four children. What is the probability that their first child wil
