You work in a laboratory that studies the molecular biology of tribbles. [Although tribbles are an alien life form, assume here that the molecular biology of tribbles is identical to that of eukaryotes on Earth.]Your lab has a genomic library of tribble DNA, as well as a cDNA library made with mRNA extracted from whole tribbles. The lab also has a collection of live tribbles that can be used to isolate RNA or DNA, and a supply of fixed tribbles that can be stained for gene expression.Your advisor provides you with a cloned 100 bp DNA fragment that represents part of the protein-coding region of a tribble gene. Using the tools described in the previous paragraph and the molecular biology techniques we have discussed in class, how would you accomplish each of the following aims? Note: try to come up with the simplest and modest direct approach that will give you the desired information.A. Determine the amino acid sequence of the complete protein produced by that gene.B. Determine whether or not the gene contains introns.C. Determine whether the RNA produced by that gene experiences alternative splicing.D. Determine the length of the mature mRNA(s) produced by the gene. This includes the UTRs and the poly-A tail.E. Determine which cells in the tribble body do and do not express mRNA from this gene.F. You discover a blood stain in the lab, and you want to determine whether it is human blood or tribble blood. How can you do this using the molecular biology tools described above?

Answers

Answer:

Explanation:

A) to determine amino acid sequence of the protein produced by that gene. We will use cDNA library, we will hybridize given part of DNA sequence ( as this part only contains exon part). Than we will isolate the hybridize part and translate this sequence using generic coding table.

B) for determine presence or absence of introns in gene used isolated cDNA in first question. Now we will add this cDNA to DNA library. Here cDNA due to complementary mature binds with DNA. If cDNA binds completely with gene with out looping part of gene it shows that gene is having only exons .

And if along with hybridization part some looped part present in between-- it shows both exons and intron are present.

C) for determining alternative splicing we will use cDNA library.

d) to determine length of mature mRNA which includes both the UTR and poly A sequence we will go for cDNA cloning and look for particular cDNA complementary to DNA segments. And later we isolate that cDNA and examine its whole length

E) to determine which cells in the tribble body express this particular mRNA . We use fluorescent tagged small DNA part provided. Then we will add this DNA probe to supplied tribes. The cells which are expressing , will have cDNA will bind to probe and florescent can be detected. Cells which are not expressing that gene, here probe will not bind and no fluorescence.

F) to determine that whose blood strain is this. We will do VBTR profiling . Which VNTR profiling similar to belief stain help to determine which blood stain is this.

In a large population, the allele frequency of A was .5 and changed to .7 over just a few generations. Which of the following statements about this example is FALSE?1. Evolution is occurring in the population.
2. The A allele is undergoing positive selection and istherefore adaptive.
3. The a allele is undergoing negative selection anddecreases fitness.
4. The population is undergoing genetic drift.
5. None of the above is false

Answers

Answer:

Option:(5)- All of them are correct.

As the change in allele frequency causes the change in genome of the living organism inside few generations.

Explanation:

The effects of change in allele frequency:

The effect may leave the organism with the loss of some genes, while it can effect cause the loss of some of the beneficial genes inside the genome of the organism. Along with that the process can also improve the sequence of genes which are abnormal in nature.

Genetic Drift:

"The change or the evolution inside the alleles frequency of the organisms genome, which may occur due to the chance events."

As the process of genetic drift occurs inside generations, which leaves the random organisms to live.

What is the layer of myelin that surrounds an axon called?Group of answer choices

1. Node of Ranvier
2. Perichondrium
3. Perimysium
4. Myelin sheath
5. Periosteum

Answers

The gaps (approximately 1 micrometer wide) formed between myelin sheath cells long the axons are called Nodes of Ranvier. Since fat serves as a good insulator, the myelin sheaths speed the rate of transmission of an electrical impulse along the axon.

I think the answer is Nodes of Ranvier but I’m not sure. I hope this helped <3

What is the y intercept of the line with the equation 4x + 2 = 12

Answers

4x-2y=12

plug in 0 to find y or x intercept: 4x-2(0)=12 4(0)-2y=12

4x=12 2y=12

x=2 y=-4

(2,0) (0,-4)

so the y-intercept is -4 and x-intercept is 2

How do you feel about the results of this activity? Were you surprised? Why or why not?

Answers

The results of an activity or experiment can either prove or disprove the initial hypothesis. Also, if they disprove the initial idea or hypothesis they are surprising.

In any activity or experiment, the results are always related to the first idea or hypothesis. In this way, the results can:

Match or prove the initial idea
Contradict or disprove the initial idea

For example, if the initial idea is "Plants require 10 ml of water to survive" by the end of the experiment you will understant if this is true or if it is false.

Moreover, if the results do not match your initial idea, then they can be classified as revealing and surprising.

Note: This question is incomplete because the activity is not included; however, I answered this question based on general knowledge.

Carbon dioxide diffuses into the ocean carbon cycle via the air-sea surface exchange. Molecules of CO2 enter the ocean by diffusing into the surface waters and dissolving. The amount of CO2 that diffuses and dissolves in the surface water depends on several variables. Scientists have noted that sea more CO2 diffuses and dissolves in colder sea surface water and less CO2 diffuses and dissolves in warmer water. Let's assume the predictions of scientists predicting a warming climate are true. Can you predict the outcome if average ocean temperatures increase as well? Include the effects on appropriate components of the biosphere as well as the hydrosphere.
