home Length of one nucleotide pair in a DNA helix: 3.4 angstroms. Average number of nucleotide pairs in a single human DNA molecule: 1.5 x 10^8. Estimated total number of nucleotide pairs in a human cell: 6 x 10^9. The average size of a human cell is 10 micrometers. The average size of the nucleus in a human cell is 5 micrometers. 1 angstrom equals 0.0000000001 meters.

- kind of reward to the winners (such as loading their gels first). • DNA is found inside every cell in our body (apart from red blood cells). • Each cell contains roughly 2 metres of DNA. • Humans have roughly 100,000,000,000,000 (100 trillion cells). • If you unravelled all of your DNA from all of your cells and laid out the DNA end to. end, the strand would stretch from the Earth to the Sun hundreds of times (the sun. is approximately 98 million miles away from Earth).

- } * * * * If you unravel all the DNA in the chromosomes of one of your cells, it would stretch out 2 meters. If you did this to the DNA in all your cells, it would stretch from here to sun more than 400 hundred times! * * DNA DNA is often called the blueprint of life. In simple terms, DNA contains the instructions for making proteins within the cell.

- DNA molecules are very long but are packed into compact structures called chromosomes chromosome: One of the rod shaped bodies found in the nucleus of cells that contain genetic information (DNA). . Each DNA molecule consists of two twisted strands of bases that form a shape called a double helix.The two strands are held together by hydrogen bonds between pairs of bases. When a cell grows and divides into two, it first has to make a duplicate copy of each DNA molecule.f A occurs in one strand of a DNA molecule it will form a bond with T in the other strand. C and G will also only bond with each other. In this way it's possible to predict the order of bases on the other strand if the bases on one strand are known.

- If completely unraveled, human DNA would stretch from the Earth to the Moon. If you stretch it and not unravel it, the distance is on average about 6 ft. (2 m) long, but is a very thin thread. The single human chromosome on average consists of DNA molecules approximately 2 inches long.f stretched out from a single cell, the DNA would be about 2-3m long. The total length of DNA present in one adult human cell is calculated by the multiplication of: (length … of 1 base pair)*(number of base pair per cell) = (0.34 × 10^-9 m)(6 × 10^9) on average. 1 person found this useful.

Where is DNA Found? Human Cells. Nucleus. DNA can be found inside the nucleus of every cell, apart from red blood cells. It's tightly wound and spread throughout the 46 chromosomes. One set of 23 chromosomes is inherited from each parent. Inside the chromosomes the DNA exists as genes. A gene is a sequence of DNA, that by and large, though there are exceptions, codes for one protein.

Length of uncoiled human DNA Total length of DNA in 1 cell: 6.4×10 9 × 3.4×10 -10 meters &approx; 2 meters. Total length of DNA of all cells in human body: 2 meters × 10 14 = 2×10 14 meters. The total length of the DNA strands in the human body in units of Pluto roundtrips is: 2×10 14 meters / 1.2×10 13 meters/Pluto roundtrip &approx; 17 Pluto roundtrips. 10 billion miles are 1.6×10 13 meters (assuming statute miles for miles – you never know exactly with uncommon units).

Unit 6: structure of DNA (8.2-8.5) Each Chromosome in a Eukaryotic cell is very long, if replication started at one place, it would take forever to be finished because there are billions of nucleotides per strand of DNA. So multiple origins of replication are needed to make the process go faster.

- DNA molecules are long — so long, in fact, that they can't fit into cells without the right packaging. To fit inside cells, DNA is coiled tightly to form structures we call chromosomes. Each chromosome contains a single DNA molecule.

How many DNA molecules are present in a human cell's nucleus? The sub questions are already answered very clearly. I will try to answer How many DNA molecules are present in a human cell's nucleus? One chromosome (non-replicated) i.e equal to one chromatid = 1 DNA molecule. One chromosome (replicated) i.e equal to 2 chromatids (aka sister chromatid) = 2 DNA molecules

- DNA for Dummies DNA is an extremely long chain of molecules that contains all the information necessary for the life functions of a cell. The individual molecules that make up DNA are called nucleotides.There are only four nucleotides that are ever used, these are Adenine (A), Thymidine (T), Guanine (G), and Cytosine (C).NA is an extremely long chain of molecules that contains all the information necessary for the life functions of a cell. The individual molecules that make up DNA are called nucleotides.

Where are DNA and RNA found in the cell? Confidence votes 38. Prokaryotic cells typically have a single molecule of DNA in a closed loop floating free in a region of the cytoplasm called the nucleoid. Many species of prokaryotes also contain DNA in tiny ringlets known as plasmids in the cytoplasm. Eukaryotic cells are typically about ten times larger than prokaryotic cells and have a nucleus containing numerous strands of DNA.
