- For another project, you designed primers 1 and 2 with the sequences shown below. Your lab partner suggests you calculate the primer melting temperatures (Tm) using the formula: Tm = [(A+T) x 2°C] + [(G+C) x 4°C]. Calculate the Tm for Primers 1 and 2 and give your answers in the boxes provided below. You must give your answer as a whole number (no decimal places). Units (°C) are already shown so must not be included in your answer. Primer 1 (forward): 5' TTCGTCTGGTGAACTCAG 3' °C Primer 2 (reverse): 5' CAGGGTATGTCCGTATAT 3' °CThe chromosome of the bacterium (prokaryote) Escherichia coli has a size of approximately 4,000 kilobases (kb) [one kilobase = 1,000 bases]. What length of DNA (B form) would be contained in it? How does this length compare to the average size and/or volume of this bacterium?There is one base pair for every 0.34 nm of DNA and the totalcontour length of all the DNA in a single human cell is 2 m.Calculate the number of base pairs in a single cell. Assumingthat there are 1014 cells in the human body, calculate the totallength of DNA. How does this estimate compare to the distance from the earth to the sun (1.5 * 108km)?
- What is the concentration of a DNA solution that absorbs 0.812 and 0.463 at 260 and 280 nm, respectively? Is the DNA solution considered to be good quality? Why or why not?One gram of cultured human cells contains about 10^9 cells and occupies roughly 1 mL. if the average molecular mass of a base is 660 daltons and each cell contains 6,4 *10^9 bp, what mass of DNA is present in this one-gram sample? If all the DNA molecules in the sample were laid end to end to form a single thread. Would it be long enough to reach from the Earth to the Moon (385.000 kilometers).The question is attached
- A packing plant fills bags with cement. The weight X kg of a bag of cement can be modelled by a Normal distribution with mean 50 kg and standard deviation of 2kg. a) If a bag is selected is at random, find the probability that the weight of the bag is greater than 55 kg. b) If three bags are selected at random, find the probability that 2 bags weigh more than 55 kg. c) Compute the probability in part a using RStudio.Pls help me with the given question and explain your correct answer, thank you A group of absent-minded scientists has two numbers (25.4 and 2.54) written on a scrap of paper. One scientists says: “I remember that one of these values was the standard deviation and the other the standard error of the mean, but I can’t remember which is which”. a)Which number is the standard deviation, and which is the standard error of the mean? b)What was the sample size? SE= s/√(2√n)Please give me correct solution for both questions c and d.
- A compact disc (CD) stores about 4.8 × 109 bits of information in a 96 cm2 area. This information is stored as a binary code—that is, every bit is either a 0 or a 1. how many bits would it take to specify each nucleotide pair in a DNA sequence? how many CDs would it take to store the information contained in the human genome?To carry out sequencing, you need to include 600 ng of DNA and a total of 6.4 pmol of sequencing primer. If your concentration of DNA (determined by A260 reading on a Nanodrop Spectrophotometer) is 89.0 ng/μL, how many μL of this sample do you need for a total of 600 ng?On the planet RAMA, the DNA is of six nucleotide types: A,B,C,D,E,F. A and B are marzines, C and D are orsines, E and F are pirines. The following rules are valid in all RAMAN DNA: total marzines=total orsines=total pirines AND A=C=E this is a theoretical planet. B=D=F. Do not attempt to research RAMA- A. Prepare a model for the structure and components of RAMAN DNA components and how it is put together. Describe in detail the structure and components in detail. How does your RAMAN model differ from the human model? B. On RAMA, mitosis produces three daughter cells. Bearing this fact in mind, propose a replication pattern for your DNA model. How would it work? How does it differ from human replication pattern? Detail your answer. C. Consider the process of meiosis on RAMA. How would it occur based on your model. Cite an example. What conclusions can you suggest regarding the outcomes of meiosis? How does it differ from the human process of meiosis? Detail your answer.
