DNA Powerpoint

Transcript: Composition How DNA Works DNA is made of subunits called nucleotides arranged in two strands. A nucleotide consists of a sugar, a phosphate, and a base. The two sides of the double helix are made of alternating sugar parts and phosphate parts The rungs of the ladder are made of a pair of bases. Adenine on one side of a rung, always pairs with thymine. DNA DNA stands for deoxyribonucleic acid. DNA is the genetic material of living things. It determines inherited characteristics. DNA looks like two twisted ladders. DNA is found in the nucleus of all eukaryotic cells. DNA contains four basic building blocks or bases: adenine, cytosine, guanine, and thymine. Fun Facts Long strands of chromatin are usually bundled loosely within the nucleus. A single strand of chromatin is made up of a long strand of DNA that is coiled around proteins. Each strand of DNA contains two halves that are connected in the middle and twisted in a double helix. When the cell is ready to divide, it has already copied its DNA. The copies stay attached as the chromatin is packaged into chromatids. Then, the two identical chromatids form a chromosome. The shape of DNA is a strand of DNA that looks like a twisted ladder. Structurally, DNA is made up of nucleotides. Nucleotides hook together to make the sugar-phosphate backbone of every strand of DNA. The bases pair up with opposite, matching bases on the other strand of DNA. The other two strands of DNA are linked together by weak hydrogen bonds and stacked like a ladder, and spirals around each other to make the double helix. In the 1950s, a biochemist named Erwin Chargaff found that the amount of denine in DNA always equals of adenine. A british chemist, Rosalind Franklin, was able to make images of DNA models. She used a process called x-ray diffraction to make the images Two other scientists named James Wattson and Francis crick, were also trying to solve how to find DNA's structure. So, Maurice Wilkins shared Franklin's data, without their knowledge, with James and Crick. DNA PowerPoint Structure Composition The pairing of bases allows the cell to replicate, or make copies of DNA. For example, the sequence CG AC will bond to the sequence CG TG. DNA is copied during the S or the synthesis phase of interphase. Two strands of DNA split down the middle so that a copy can be made. A new strand forms along each of the original strands. James Wattson and Francis Crick. History Each cell contains nine feet of DNA. In an average meal, you eat approximately 55 million cells. A human genome is approximately 3 billion base pairs in length (haploid). It takes 8 hours to completely copy its DNA. DNA was first isolated in 1869 by Friedrich Meischer. Every living thing has DNA, like a tree, a zebra, and a mushroom. Replication Process

Transcript: DNA is a fragile molecule. About a thousand times a day, something happens to it to cause errors. This could include errors during transcription, damage from ultraviolet light, or any of a host of other activities. There are many repair mechanisms, but some damage isn't repaired. This means you carry mutations! Some of the mutations cause no harm, a few are helpful, while others can cause diseases, such as cancer. X chromosome HTTP://PREZIWORLD.COM Every human being shares 99% of their DNA with every other human. Even though it codes for all the information that makes up an organism, DNA is built using only four building blocks, the nucleotides adenine, guanine, thymine, and cytosine. Scientists at Cambridge University believe humans have DNA in common with the mud worm and that it is the closest invertebrate genetic relative to us. In other words, you have more in common, genetically speaking, with a mud worm than you do with a spider or octopus or cockroach. If you could type 60 words per minute, eight hours a day, it would take approximately 50 years to type the human genome. Y GET THIS TEMPLATE You have 98% of your DNA in common with a chimpanzee. chromosome A parent and child share 99.5% of the same DNA. If you put all the DNA molecules in your body end to end, the DNA would reach from the Earth to the Sun and back over 600 times (100 trillion times six feet divided by 92 million miles). Humans and cabbage share about 40-50% common DNA.

DNA POWERPOINT

Transcript: THE STRUCUTR OF DNA IS CALLED A DOUBLE HELIX and the two strands of the DNA must be separated , the weak hydrogen bonds are broken. Once all of that is done they must be held together to allow new nucleotides to be parther together. a enzyme named DNA polymerase moves along the uncovered dna and creates new bonds creating new nucleotide . DNA ENDING by tyler bates first separated by a twisted strand into two untwisted molecular, this happens is a area of the chromesomes called the origins. the enzyme that does this is a helicase because it unwinds the strands. then an enzyme called dna polymerse copies each strand using the base pairing rule. both of the strands are not copied te same way also the DNA polymerse enzyme doesn't do it all of its own it has the help of other enzymes. What is DNA? DNA Strucutre ( Double helix) DNA IS : Deoxyribonucleic acid is a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses nucleotides are also made up of deoxyribose sugar Dna is made up of molecules called nucleotides. each nucleotide contains phroopshate groups. the nitrogen bases are called cytosine, thymine, adenine and guanine. the smaller bases are always paired with the bigger ones DNA Replication With these facts. this shows you what DNA is and more of a clear in site of what's going inside of our bodies. first the DNA is unwound... how copies of DNA are written and copied DNA POWERPOINT

Transcript: Jacques Monod and François Jacob (1965) DNA Structure Once all of the bases are matched up an enzyme strips away the primer. The gaps where the primer were are then filled by more complementary nucleotides. The new strand is proofread to make sure there are no mistakes Finally, an enzyme called seals up the sequence of DNA into two continuous double strands. the new DNA automatically winds up into a double helix. l Definition of DNA DNA by : Anahita Moayedifar Jacques Monod and François Jacob were the first to discover how genes were turned on and off. l Gregor Mendel discovered the fundamental laws of inheritance. He found out that genes come in pairs and are inherited. l Thomas Hunt Morgan established the chromosomal theory of inheritance. Leading strand DNA, or deoxyribonucleic acid, is the gene material in humans and almost all organisms. DNA is past down from parent to offspring. A offspring has some genes from both the parents. DNA Composition DNA is a molecule that transfers genetic messages to every cell of your body. When an egg and sperm met to form the first cell that was later to become you you, you were given the complete genetic code that all of your cells will use for rest of your life. DNA is like a boss and its workers, the boss gives information to its workers to do a certain job. DNA Powerpoint History of DNA: Timeline Sugar Phosphate Backbone Base pairs Cytosine Adenine Thymine Guanine ________________________ How DNA Works The first step in DNA replication is to ‘unzip’ the double helix of the DNA This is carried out by an enzyme which breaks the bonds holding the complementary bases of DNA together The two separated strands will act as the templates for making the new strands of DNA One of the strands is placed in the 3’ to 5’ direction, this is the leading strand. The other strand is moved in the 5’ to 3’ direction, this is the lagging strand. As a result of their different positions, the two strands are replicated differently Multiple RNA primers are made by the enzyme and bind at different points along the lagging strand. Chunks of DNA are then added to the lagging strand also in the 5’ to 3’ direction. This type of replication is called discontinuous Alfred Hershey and Martha Chase (1953) Adenine (A) Thymine (T) Guanine (G) Cytosine (C) Phosphate Gregor Mendel (1866) Alfred Hershey and Martha Chase did the Hershey-Chase blender experiment that proved phage DNA, and not protein, was the genetic material. Thomas Hunt Morgan (1911) DNA DNA Replication Process Lagging strand A piece of RNA comes along and binds to the end of the leading strand. The primer acts as the starting point for DNA synthesis. DNA polymerase binds to the leading strand and then goes along it, adding new complementary nucleotide bases to the strand of DNA in the 5’ to 3’ direction. This sort of replication is called continuous. l
