What is simile for DNA?
There have been no shortage of contenders, from “double helix” (which describes its shape rather than function) to “blueprint”, “chemical building block”, “alphabet of life”, “book of life”, “computer code of life” and even “symphony of life”.
What is A metaphor for DNA?
“DNA is often referred to as a ‘blueprint for life’. A blueprint is an architect plan, technical drawing or engineering design. Like a blueprint, DNA contains information to guide construction, in this case of a living organism. Beyond that, the analogy rapidly breaks down.
What is A correct example of base pairs in DNA?
Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .
What is A good analogy for chromosomes?
A chromosome is like a flash drive or a book because they store information.
What is the best analogy for DNA?
Translation Analogy
- The DNA is the set of instructions for the cell – like a cook book is the set of instructions for a restaurant.
- A single DNA instruction is a gene – this is akin to a single recipe in a cook book.
- Transcription is the process of making an RNA copy of a gene – RNA polymerase is like a photocopy machine.
How is DNA like A recipe book?
Think of DNA as a collection of cookbooks that contain all the recipes for making and running living things like worms, plants, birds, and people. These recipes determine your height, give you your eye and hair color, and tell your body to have two arms and legs, instead of branches and leaves, or tentacles.
How is DNA like a recipe book?
What is the correct DNA base pair matching?
The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)
What are the complementary bases of adenine thymine guanine and cytosine?
Adenine and guanine are purines, while thymine, cytosine and uracil are pyrimidines….DNA and RNA base pair complementarity.
| Nucleic Acid | Nucleobases | Base complement |
|---|---|---|
| DNA | adenine(A), thymine(T), guanine(G), cytosine(C) | A = T, G ≡ C |
| RNA | adenine(A), uracil(U), guanine(G), cytosine(C) | A = U, G ≡ C |
What are chromosomes like in a city?
| Cell Organelles | City Analogies |
|---|---|
| Lysosomes | Waste Disposal/ Recyclers |
| Vacuole | Warehouses, water towers or garbage dumps |
| Protoplasm | Air or atmosphere |
| Chromosomes | Rolled up blueprints |
What is an analogy for DNA and RNA?
Because DNA or books cannot be removed from the library a copy must be made. This copy is messenger RNA which is taken to the factories for the production of goods. There may be more than one factory in the town. However, each of these factories will produce a portion of the total product for the town or cell.
What is an analogy for DNA polymerase?
DNA polymerase is the enzyme that synthesizes DNA from single bases when making a new helix. Some bases are complete, like the normal LEGO® blocks and some are modified, like the flat-topped LEGO® blocks. When DNA polymerase selects a base randomly, it has a chance to choose modified or normal nucleotide bases.
Why do you think the analogy of DNA being a cookbook and RNA being the recipe is a good analogy of this relationship?
The DNA is the set of instructions for the cell, just like a cook book which is the set of instructions for a restaurant. A single DNA instruction is a gene which is akin to a single recipe in a cook book. RNA polymerase is like a photocopy machine and transcription is the process of making an RNA copy of a gene.
How is a cells DNA like the books in a library?
The cell’s DNA is like the books in a library because a larger cell would have to make greater demands on its available genetic “library”. In time, the cell’s DNA would no longer be able to serve the increasing needs of the growing cell, like a town growing in size borrowing books from a small library.
Which of the following are complementary nitrogenous base pairs i a/g II C T III T A?
In DNA, the complementary bases are adenine and guanine ; thymine and cytosine. Each nucleotide in DNA is composed of a nitrogen containing base, either guanine (G), adenine (A), thymine (T), or cytosine (C) as well as a monosaccharide sugar called deoxyribose and a phosphate group.
What is A complementary strand of DNA example?
Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine. This means that the two strands are complementary to each other. For example, a strand of DNA with a nucleotide sequence of AGTCATGA will have a complementary strand with the sequence TCAGTACT (Figure 9.8).
What is a good analogy for nucleus?
Analogy: The nucleus is like the brain of a human because the brain controls the actions of the body like the nucleus controls the cell.
What is an example of a base pair in DNA?
An example of a base pair is adenine pairing with thymine. This occurs in the DNA molecule. Adenine forms two hydrogen bonds with thymine, allowing them to pair together.
How are the two strands of DNA linked together?
There are chemical cross-links between the two strands in DNA, formed by pairs of bases held together by hydrogen bonds. They always pair up in a particular way, called complementary base pairing: thymine pairs with adenine (T-A) guanine pairs with cytosine (G-C)
What are the rules of complementary base pairing in DNA?
Base Pair Rules in DNA Watson & Crick base pairs follow a specific rule of hydrogen bonding. In complimentary pairing, one purine links with one pyrimidine nucleic base. In DNA, specifically, adenine only pairs with thymine to form two hydrogen bonds.
What nucleotides are identical to the base?
The nucleotides are identical except for the base, which can be an adenine, thymine, guanine or cytosine. There are chemical cross-links between the two strands in DNA, formed by pairs of bases held together by hydrogen bonds. They always pair up in a particular way, called complementary base pairing: thymine pairs with adenine (T-A)
