Concept explainers
Interpretation:
The minimum length of a DNA sequence that will appear only once in the human genome needs to be determined, if the human genome contains 3 billion nucleotides arranged in a vast array of the sequence. This is to be taken into account that only one strand and all four nucleotides have the same probability of appearance.
Concept introduction:
Deoxyribonucleic acid (DNA) is a molecule consisting of two strands that twist around each other to create a double strand DNA containing directions for the development, working, growth and breeding of all recognized species and many bacteria. It is also recognized as polynucleotides. The two DNA sections consist of simpler monomeric blocks called nucleotides.

- . In a supercoiled DNA, a stretch of about 20 base pairs changes from the B form to the Z form. What is the change in (a) T, (b) L, and (c) W?arrow_forwardPissssssssss helppppppppp, One strand of DNA reads T-A-C-G-A-G-C-T-C. Describe the steps of protein synthesis of a eukaryotic cell using the nitrogen bases of the given DNA strand. Include the following terms in your description (1 paragraph pls): -DNA - mRNA -protein -tRNA -Amino acid -codon -nucleus -Ribosome -cytoplasm -transcription -translationarrow_forwardDNA Stability/Chapter 4 A solution of DNA contains two different DNA molecules. Molecule 1 is 500 base pairs and contains 100 A’s. Molecule 2 is 500 base pairs and contains 300 A’s. (1) How many AT base pairs and GC base pairs is in each DNA molecule? (2) How many, G’s, A’s, T’s and C’s are in each molecule? (3) Draw one figure that shows the relative melting temperature of the two DNA molecules.arrow_forward
- 22arrow_forward. While studying the structure of a small gene that was recently sequenced during the Human Genome Project, an investigator notices that one strand of the DNA molecule contains the following: 20 adenine (A) bases 30 cytosine (C) bases25 guanine (G) bases 22 thymine (T) bases How many of each base is found in the complete double-stranded molecule?arrow_forwardWhen Chargaffwas performing his experiments, the tetranucleotide hypothesis, which stated that DNA was composed of GACT nucleotide repeats, was the most widely accepted view of DNA’s composition. How did Chargaff disprove this hypothesis?arrow_forward
- Below is a sequence of 540 bases from a genome. What information would you use to find the beginnings and ends of open reading frames? How many open reading frames can you find in this sequence? Which open reading frame is likely to represent a protein- coding sequence, and why? Which are probably not functioning protein-coding sequences, and why? Note: for simplicitys sake, analyze only this one strand of the DNA double helix, reading from left to right, so you will only be analyzing three of the six reading frames shown in Figure 19.4.arrow_forwardHuman Genome Replication Rate Assume DNA replication proceeds at a rate of 100 base pairs per second in human cells and origins of replication occur every 300 kbp. Assume also that human DNA polymerases are highly processive and only two molecules of DNA polymerase arc needed per replication fork. How long would it take to replicate the entire diploid human genome? How many molecules of DNA polymerase does each cell need to carry out this task?arrow_forwardDNA contains many hydrogen bonds. Are hydrogen bonds stronger or weaker than covalent bonds? What are the consequences of this difference in strength?arrow_forward
- 49 N), heavy parental DNA, and all nucleotides with 14N (another isotope of N) as "nucleotide supply source" for DNA replication in a tube. Use the figure provided below to illustrate the arrangement of light and heavy isotopes of nitrogen in DNA molecules formed in Generation one, two and three. (Please use the shade or different color to represent the daughter strands of DNA with light N-isotope, so as to be different from the parental DNA strands.) Make sure to label what each color represents clearly. Otherwise, the answer is not considered correct. semiconservative replication ப Generation Zero (Original DNA) Generation One Generation Twoarrow_forwardPlease send me the question in 10 minutes it's very urgent plzarrow_forwardDNA Structure A. Draw an A-T base pair with the appropriate number of hydrogen bonds. You don’t have to include all the details such as every side-group but do depict the 3’ OH groups. B.
