Each strand consists of alternating molecules of deoxyribose and phosphate groups. Each step is made up of a double ring purine base and a single ring pyramiding base. The purine and pyrimidine bases and a single ring pyramiding base. The purine and pyrimidine bases are connected to deoxyribose sugar molecules. The two strands are interwined in a clockwise direction, i.

They include chewing gum science projects, soda pop science projects, magnet science projects, and making a DNA model for Model of social development of a science project. You cannot mix colors between pairs. DNA, like RNAis Homework making a dna model nucleic acid that contains the genetic information for the reproduction of life. Thread through the centers of each alternating string of styrofoam sugar and phosphate balls. Did this article help you? Make sure to use an even space between beads. Rated this article:. Choose six colors of pipe cleaners, and cut them each into 1-inch long pieces. The yellow balls will represent the phosphate component and the red balls will represent the sugar component of DNA. This article was co-authored by Bess Ruff. The great thing about making DNA models is that you can use almost any type of material. Leave the other 2 pipe cleaners at their full length. Here you will Stranger masturbation how to construct a DNA model Homework making a dna model candy. Attach your gummy bears to the licorice.

- Building a model of a DNA helix in class will help students visualize DNA's construction and learn about the life-giving genetic code.
- Making DNA models can be informative, fun, and in this case tasty.
- Cut red and black licorice into 1-inch long pieces.
- Making a model of DNA is a great way to learn about how this magnificent structure builds our genes and determines our genetic makeup.
Your friends are people who have the same likes or dislikes that you do, and who you like spending time with. Your family all share the same DNA , which are tiny molecules in your body that have information about your genes.
Your genes make up who you are — from the colour of your hair to the length of your toes. Your friends might not always share your DNA you can be friends with your family too! For example, you might like the same games, television shows or hobbies. Sometimes we talk about families in terms of generations. A generation is all the children who have the same mum. Your mum and dad are one generation older than you, and your grandparents are two generations older.
Your cousins are the same generation as you. People who are related to each other have some of the same DNA. DNA is a tiny chain of tiny molecules in your body, and it has information about your genes. Genes make up who you are. You get some genes from your mum and her family, and some from your dad and his family. A family tree shows how people in a family are related.

Access thousands of brilliant resources to help your child be the best they can be. Who are family and friends? Family members can be your friends too — friends are people who like spending time together, and that can include your brothers, sisters, cousins, mum and dad.
Your mum and dad are called your parents, and brothers and sisters are your siblings. There are lots of different kinds of families, and they all have different relationships in them. You can learn about people in your family who have died by asking gran and granddad, or looking up old records of when people were born, when they got married and when they died.
You can meet people who might become your friend just by saying hello, and asking them about the sorts of things they like to do. Your family is more than the people you live with — you might have cousins, aunts, uncles and grans who live somewhere else but are still part of your family.
Children whose mum or dad might not be alive, or able to care for them anymore might be adopted or fostered into another family. That means they might not look like their new mum or dad, but they live together and care for each other.
Everyone might still call each other mum, dad, brother and sister. If your mum or dad has sisters and brothers, they are your aunts and uncles.

You should have eight blue and green stems and eight purple and orange stems representing the DNA's nitrogenous bases. This DNA model is a bit more complicated than the others, and it requires more expensive art supplies. A Anonymous May 1, Choose six colors of pipe cleaners, and cut them each into 1-inch long pieces. You cannot mix colors between pairs. Twist the blue and green pipe cleaners together in pairs and twist the purple and orange pipe cleaners together in pairs. Updated: September 6,

You can visit assignmenthelp. Deoxyribonucleic acid also called DNA, is an important molecule that carries genetic information from one generation to the other. Though Watson and Crick were the first one to give exact structure of DNA, but before them several scientists and researchers with their experiments and findings have discovered several information about this molecule of life. Nucleic acid and gene were separately discovered but no one was able to draw a connection between the both.
In , American scientist Oswald Avery from his experiment in the bacteria proved that genes where made of nucleic acid. Likewise a Russian biochemist- Phoebus Levene was the first to find out about the phosphate-sugar-base components of a single nucleotide and also the first one to discover the carbohydrate component of DNA and RNA.
Likewise, Chargaff- the Australian biochemist , elaborated the findings of Levene and proposed two main information from his findings and experiments. First- the composition of nucleotide varies in DNA among species, second- the amount of adenine is equal to thymine, whereas the amount of guanine is similar to cytosine. This concludes that total amount of purines and the total amount of pyrimidine are nearly equal.
Therefore, before the discovery of DNA structure; much of the work was already done by different scientists. While other scientist were using experimental methods to discover the structure of DNA, Watson and Crick worked with stick and ball models to find out about the structure of DNA. Therefore after lots of hard-work and tests, in ; Watson and crick was able to expose helical structure of DNA.
They also discovered the unidentified fact about base pairing from the work of Erwin Chargaff, which is also called Chargaff rule of base pairing. If you want to receive detailed information about the work of researchers and scientists on the structure of DNA to write your assignment, you can submit your question at assignmenthelp.
RNA is another molecule that was of interest for researchers. All other features are same as that of DNA. Besides these all other structures are almost similar in both these molecules. Looking for more detailed information on this topic? Want some diagrams and images for accurate understanding? Just give a call at assignmenthelp. You will be replied immediately by our tutors.
DNA is molecule of life that carries genetic information. Different scientists discovered one or the other information related to the structure of DNA, but it was Watson and Crick who gave the actual model of DNA depending on the prior investigation and researches done by other scientists.
Soon after the discovery of DNA, research on RNA started and hence it was concluded that both these molecules are almost structurally similar with very few differences between them. Online Customer Service. Submit your requirement.
