Briefly explain how DNA profiling is used to identify individuals.

Answers

Answer 1
A sample of DNA is taken from blood of saliva. PCR makes lots of copies, or amplifies the DNA. We then add restriction enzymes to cut the DNA at palindrome sequences. We then run the DNA through gel Elecrophoresis. Each person has unique short tandem repeats that cause a unique number of cuts by the restriction enzyme. These cuts are separated by size on gel electrophoresis, so no two people have the exact same pattern. We can compare individuals banding patterns to what is found at a crime scene, taken in previous samples, in a baby, and the sample that matches all the banding patterns will be the individual.

if the dna sequence is TAC CCC AAG CTC GGT ATC. what is mRNA

tRNA

AA?

Answers

The mRNA sequence would be:

AUG GGG UUC GAG CCA UAG

The mRNA sequence is complementary to the DNA sequence, in other words would just basically mean you do the opposite of the bases to the DNA sequence such that:

Cytosine with Guanine

Thymine (uracil for RNA) with Adenine

However, mRNA has Uracil instead of Thymine, so instead the uracil in mRNA binds with adenine.

Urcacil with Adenine

For tRNA, they have anticodons, meaning they have bases complementary to the mRNA strand, so the tRNA with the complementary anticodon sequence would be:

UAC CCC AAG CUC GGU AUC (DNA sequence but replace thymine with uracil)

For the amino acids, they would bond to the specific tRNA molecules with the specific bases on the anticodons.

Mark Twain satirizes the long list of names to refer to some noble people.

Satire is a common literary element in Twain's texts. Twain often uses satire as a way to ridicule the attitudes and behavior of some people, especially wealthy or noble people.

In the excerpt presented, Twain is satirizing the long names of noble people. This is seen in the following excerpt:

Their daughter the Lady Anne-Grace-Eleanor-Celeste-and-so-forth-and-so-forth-de-Bohun

In this excerpt, he jokes about the long name of one of the guests and shows how ridicule is to have these very long names.

The stage of cell respiration that is being shown above is oxidative phosphorylation. During this stage, the transport of electrons is coupled to the generation of an electrochemical gradient.

Cellular respiration can be defined as a series of metabolic reactions by which aerobic cells generate energy in the form of ATP.

Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.

During oxidative phosphorylation, the transport of electrons across the mitochondrial membrane is coupled to the generation of an electrochemical gradient, which is then used to generate ATP by an ATP synthase as shown in the figure.

A. There would be an overpopulation of caterpillars, which would threaten the oak trees

Explanation:

Because sparrows eat caterpillars as a primary food source, when the population of sparrows decrease, the population of caterpillars will increase. Because of this, more caterpillars will be feeding off of the oak trees, therefore threatening the oak trees. I hope this helps!

What is rock cycle ?

Rocks are naturally occurred on non-living earth which are made by collection of  mineral grains held together in a firm, it can be tiny or big as well and can be easily identified with their texture.

The Rock cycle can be defined as a continuous process through which old rocks are transformed into new rock due to cool down of molten magma, when it solidifies become igneous rock.

In a rock cycle, when the break down of these igneous rocks occur  small particles that are transported and deposited to form sedimentary rocks,  When the igneous and sedimentary rocks heated up and under the pressure they change into metamorphic rocks.

The metamorphic rocks which are subjected under great heat and pressure melt down to form molten magma which again can cool down and solidify into igneous rocks

If you cross two organisms that are heterozygous for a trait, what percent of
the offspring would you expect to express the recessive phenotype?

Answers

Answer:

25%

Explanation:

Here's an example: two chickens have the phenotype of white feathers and brown feathers. What percentage of the chicks will have the recessive color? First, you have to see the parents' phenotypes. Draw a punnet square. Put one of the parent's phenotypes (w and B) on the top, and the other parent's (w and B) on the right side going down. Whichever trait is dominant (brown) MUST be capitalized. Then, cross the two parents. first box on the top left would read 'ww.' The one below it is 'Bw' (put the dominant first). The right top is 'Bw' and the one below it is 'BB'. So if there were 4 offspring, these would be their genotypes: 'ww', 'Bw', 'Bw', and 'BB'. The only offspring that would have the recessive trait is the 'ww' child, because dominant overpowers recessive. So 25% would have the recessive trait and 75% would have the dominant trait.

How is it possible to find the
number of heterozygotes in a
sample population, given the
allele frequencies?

Answers

Explanation:

The frequency of heterozygous individuals. Answer: The frequency of heterozygous individuals is equal to 2pq. In this case, 2pq equals 0.32, which means that the frequency of individuals heterozygous for this gene is equal to 32% (i.e. 2 (0.8)(0.2) = 0.32

To find the number of heterozygotes in a sample population, we need to know the allele frequencies and the total number of individuals in the population. The formula used to calculate the expected number of heterozygotes in a population is based on the Hardy-Weinberg equilibrium principle.

The Hardy-Weinberg equation is given as:

p² + 2pq + q² = 1

Where:

p = frequency of one (dominant) allele

q = frequency of the other allele (recessive) allele

p² = expected frequency of homozygous dominant individuals

2pq = expected frequency of heterozygous individuals

q² = expected frequency of homozygous recessive individuals

To find the number of heterozygotes, we can multiply the expected frequency of heterozygotes (2pq) by the total population size. This will give us an estimate of the number of individuals in the population who are heterozygous for the specific gene of interest.
