From the time an organism is first conceived until the time it dies, it has undergone an estimated 10 quadrillion divisions (that's 1 trillion times 10 thousand, for those keeping score at home). That's a pretty big number. The human genome has roughly 4 billion base pairs. What would happen if human DNA manufacturing & proofreading machinery erred at a rate of 1 in a million? What about 1 in a billion? 1 in a trillion? What number must be reached to be compatible with life & yet not so cumbersome such that the cell has no energy left for any other growth or manufacturing?

What does the future hold for genomes? How will they be different in 100, 1,000, 1 million, or 1 billion years? Make this a long discussion.
The accuracy of DNA replication in the human germ-cell line is such that on average only about 0.6 out of the 6 billion nucleotides is altered at each cell division. Because most of our DNA is not subject to any precise constraint on its sequence, most of these changes are selectively neutral. Any two modern humans picked at random will show about 1 difference of nucleotide sequence in every 1000 nucleotides. suppose we are all descended from a single pair of ancestors—Adam and Eve—who were genetically identical and homozygous (each chromosome was identical to its homolog). Assuming that all germ-line mutations that arise are preserved in descendants, how many cell generations must have elapsed since the days of Adam and Eve for 1 difference per 1000 nucleotides to have accumulated in modern humans? Assuming that each human generation corresponds on average to 200 cell-division cycles in the germ-cell lineage and allowing 30 years per human generation, how many years ago would this…
Given the fact that 1 fg of DNA = 9.78 * 105base pairs (on average), you can convert the amount of DNA per cell to the lengthof DNA in numbers of base pairs. (a) Calculate the number of basepairs of DNA in the haploid yeast genome. Express your answer inmillions of base pairs (Mb), a standard unit for expressing genomesize. Show your work. (b) How many base pairs per minute weresynthesized during the S phase of these yeast cells?
How many Illumina clusters would you need to generate 15X coverage of the human genome, assuming your read lenght is 600 bp? (assume a human genome size of 3 billion bp) - 2.5 billion - 75 million - 7 million - 100 million

Why mammals genomes are way longer than simple organisms, such as birds and insects, even though the number of genes is not that different?
Concept 23. A gene is a discrete sequence of DNA nucleotides. This concept describes the discovery of the DNA sequencing technique that made modern biology and bioinformatics possible. The method was later used to sequence the human genome and genomes of many other organisms. This led to the accumulation of great numbers of nucleotide and protein sequences in the numerous databases. The concept 23 web page is here: http://www.dnaftb.org/23/ After reading the Concept page, answer the following questions. What was the Mendel’s definition of a gene? How was it different from the definition by Beadle and Tatum? Describe proteins based on the early sequencing efforts. What was the definition of a protein coding gene based on the genetic code? What are the beginning and ending codons of the gene’s protein coding sequence? What is the name of the method that makes use of a “defective” DNA nucleotide? After reviewing the Animation pages, answer the following…
Junk DNA — Not So Useless After All https://healthland.time.com/2012/09/06/junk-dna-not-so-useless-after-all/ (Claim) Summarize scientist's error in naming noncoding DNA "junk" DNA. (Evidence) Is the amount of DNA an organism has correlated to intelligence or complexity? (Reasoning) What are two discovered uses of noncoding DNA (introns)?
Human Genome ProjectIn 2003, the Human Genome Project was successfully completed, determining the exact sequence of the entire human genome, which is made up of 3 billion nucleotide base pairs. The data generated from the Human Genome Project is freely available online to anyone. Many pieces of research and innovations stemmed from the HGP, allowing the identifications of 1 800 disease genes. Many of the corporations using the results from the HGP are privately funded, and research is being done for profit even though the HGP results are provided freely. Identify one advantage and one disadvantage of corporate funding and patenting genetic research results.
