In the gel electrophoresis lab, you determined the genotype of three different DNA samples.
Gel electrophoresis is a process that allows you to separate fragments of DNA based on size. You place different size fragments of DNA into a gel, then apply current to the buffer surrounding the gel, the DNA will travel through the gel but move at different speeds based on the different fragment sizes. Larger fragments of DNA will move slower than smaller fragment sizes.
Let consider two different alleles:
the bigger allele -- Athe smaller allele -- aThe bigger allele happens to contain a restriction site that is allowed to be cleaved by a restriction enzyme while the smaller allele has a mutation in the restriction site that means that it will not be recognized and cleaved by that same restriction enzyme.
Let us remember that the person will have two copies of this gene and can be:
H0m0zygous dominant AAh0m0zygous recessive aaheterozygous AaAn individual with h0m0zyg0us AA only have versions of the gene that will be cut by the restriction enzymes, each allele producing a small fragment of DNA and a medium-size fragment of DNA
An individual with the genotype aa only has the version of the gene that does not have the restriction site and therefore does not get cut by the restriction enzyme. The DNA sample from this individual will have a single larger fragment of DNA.
When you isolate DNA from heterozygous Aa, half of the DNA isolated has the allele with the restriction site that gets cut into two fragments while the other half will have the allele that does not have the restriction site and remains whole when a restriction enzyme is added.
Therefore, we can conclude that in the gel electrophoresis lab, you determined the genotype of three different DNA samples.

19. Engineer It In some rivers and lakes, dams
are constructed to harvest energy by converting the
kinetic energy of moving water into electrical energy.
Water from behind the dam flows through a turbine
that transforms kinetic energy into mechanical
energy. The turbine turns a generator that converts
mechanical energy into electrical energy.
The water from behind the dam could flow to the
turbine either through an opening near the middle or
top of the dam or by flowing over the top of the dam.
Which type of water flow would be the best design for
sending a consistent flow of water past the turbines?
Explain your reasoning.
Answer:
A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy—mechanical energy is also known as kinetic energy. As the water flows down through the dam its kinetic energy is used to turn a turbine.

Does the waxy cutie affect where acertain pla y could be grown? Why?
Waxy skin - some leaves have a thick, waxy skin on their surface. This reduces water loss by transpiration . Water storage - some plants, known as succulents, store water in their stems, leaves, roots or even fruits.
The waxy covering on plant leaves, young stems, and fruit is called the "cuticle". ... The purpose of this covering is to help the plant retain water. In arid regions, that is very important. In wetter regions, the waxy coating may help prevent infection by disease organisms.
Plants that grow in arid zones of USDA zones 9 to 11 use waxy leaves to limit transpiration and retain water but also to protect leaves from the frigid temperatures sometimes found in the desert. Trees like the desert willow (Chilopsis linearis) have narrow, waxy leaves and striking purple flowers.

When muscle tissue is exercising under anaerobic conditions, the production of ______ is important because it ensures a continuous supply of NAD
Given what we know about the biological mechanisms behind anaerobic exercise, we can confirm that the production of lactate ensures a continuous supply of NAD.
In order for us to undergo any physical exercise, it is imperative that we are able to produce energy within our cells. The energy used by cells is in the form of a molecule by the name of ATP, which is produced primarily through a process known as Glycolysis.
This is relevant given that in order for glycolysis to happen, a key protein is required known as NAD+. Lactate is produced from pyruvate only under anaerobic conditions because these are conditions that lack oxygen which is the only other source of NAD+, therefore, pyruvate must be converted to lactic acid to make it possible to continue glycolysis and the production of ATP.

How is genomics related to genes and DNA?
Answer:
A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.
Genomic DNA, or gDNA, is the chromosomal DNA of an organism, representing the bulk of its genetic material. ... In research, genomic DNA is useful tools in applications such as PCR, library construction, Southern blotting, hybridizations, SNP analysis, and molecular diagnostic assays.
Answer:
DNA
DNA is the molecule that is the hereditary material in all living cells.
Genes are made of DNA, and so is the genome itself. A gene consists of enough DNA to code for one protein, and a genome is simply the sum total of an organism's DNA.
DNA is long and skinny, capable of contorting like a circus performer when it winds into chromosomes. It's skinny as a whip and smart as one too, containing all the information necessary to build a living organism. In a very real sense, DNA is information.
WHAT IS DNA MADE OF?
DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide.
Each nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base. The nitrogenous base is the part of the nucleotide that carries genetic information, so the words "nucleotide" and "base" are often used interchangeably. The bases found in DNA come in four varieties: adenine, cytosine, guanine, and thymine—often abbreviated as A, C, G, and T, the letters of the genetic alphabet.
How did people find out that DNA is the hereditary material?
DNA was largely ignored for decades after a German chemist, Friedrich Miescher, first isolated the white, slightly acidic substance from the nucleus of cells in 1869. No one knew what DNA's function was—in fact, some doubted that it had a function at all—so they pretty much left the stuff alone.
Very few people thought that DNA could be the hereditary material. Early studies of DNA suggested, erroneously, that the molecule was made up of the same sequence of four bases repeated over and over—ACGTACGTACGT… for example. No one could imagine how such a monotonously simple molecule could contain the information necessary to build a living organism.
But during the 1930s and 1940s, new experiments began to suggest that DNA might, in fact, be important. It turned out that different strains of bacteria can exchange DNA and that when they do certain traits, such as the ability to cause disease in humans, can be passed from one strain of bacteria to another. Scientists also learned that when a virus infects a cell it injects its DNA into the cell, which then produces many copies of the virus, suggesting that DNA contains instructions for building viruses. And they found that different species of organisms have different proportions of bases in their DNA—one species might have DNA that is 30 percent A, 20 percent C, 20 percent G, and 30 percent T, while another might have 20 percent A, 30 percent C, 30 percent G, and 20 percent T. People began to think that genetic information might be written in the differences between the DNA bases of different species.
What does DNA look like?
A DNA molecule is a double helix, a structure that looks much like a ladder twisted into a spiral. The sides of the ladder are made of alternating sugar and phosphate molecules, the sugar of one nucleotide linked to the phosphate of the next. DNA is often said to have a sugar and phosphate "backbone."
Each rung of the ladder is made of two nitrogenous bases linked together in the middle. The length of a DNA molecule is often measured in "base pairs," or bp—that is, the number of rungs in the ladder. Sometimes, this unit of measurement is shortened simply to "bases."The structure of DNA was worked out in 1953 by James D. Watson and Francis Crick, who worked together in the Cavendish laboratory in Cambridge, England. By the time they began their work in the early 1950s, it was clear that DNA is the hereditary material, and scientists were racing to find out more about the long-ignored molecule, picking apart the implications of each new detail. Everyone knew they couldn't really understand how DNA works until they understood how its nucleotide building blocks are put together.
