Transcription is the copy process of a segment of the DNA template strand to produce mRNA. The blue segment is DNA, and the yellow segment is mRNA.

<h3>What is transcription?</h3>

The first step before protein arrangement is to synthesize messenger RNA, mRNA.

Transcription is the synthesis of the messenger RNA, mRNA. This event occurs in the nucleus and uses fragments of DNA molecules to do it.

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: the coding strand and the template strand.

The coding strand goes in direction 5' to 3',

The complementary strand -template strand- grows in direction 3' to 5'.

The template strand is the one that is going to be complemented by the mRNA. RNA polymerase is in charge of reading the original DNI strand for mRNA synthesis.

mRNA molecule grows complementing DNA base sequences. This is,

DNA mRNA

adenine ⇔ uracil

guanine ⇔ cytosine

thymine ⇔ adenine

cytosine ⇔ guanine

Once mRNA synthesis is over, the molecule leaves the nucleus to start the transcription process in the cytoplasm.

Answer:

The blue segment is DNA molecule

The yellow segment is mRNA molecule

1- DNA molecule

2- Separation of the DNI molecule into two strands and mRNA molecule growing.

3- mRNA molecule already synthesized and separated from DNA

Consider this scenario between Josh and Julie Josh met Julie in line at a taco truck near campus and noticed she ordered extra h

Artyom0805 [142]

Answer:

The right matching of the scenario in the question are as follows:

1. OBSERVATION: Josh noticed that Julie ordered extra hot peppers and added hot sauce to her food

2. QUESTION: Josh wondered how to cook spicy Mexican food.

3. HYPOTHESIS: Josh decided jalapenos would be a good ingredient to add spice to the recipe.

4. EXPERIMENT: After chopping the jalapenos, he slowly added some to the enchilada filling, tasting as he went until he thought it was spicy enough.

5. RESULTS: Julie thought the enchiladas were delicious and exactly the right level of spice.

6. CONCLUSION: Josh determined that since Julie liked the meal, adding jalapenos to the recipe was a good way to make it spicy.

Explanation:

Scientific method is an organized steps of procedures that scientists used to study and gather knowledge about different phenomenons. The systematic steps of scientific method start with observation, the observed phenomenon usually make a scientist to ask questions that he doesn't have an answer to. This will prompt him to formulate an hypothesis and set up an experiment to see if his hypothesis is true or not. The result he obtains from the experiment will determine the type of conclusion he will make about his earlier observation. By following these steps, scientists usually obtain useful information that bring progress and advancement to humanity.

An imbalance in blood glucose levels causes which of the following diseases?

Tatiana [17]

The answer would be C. Diabetes is a metabolic disease wherein the cells of the body cannot properly respond to insulin or the body has a low production of insulin. Sometimes, it can be both. Insulin acts as the balancing hormone for the glucose in the body. Without it, glucose cannot be properly absorbed by the body as energy and nutrients. They just become glucose build-ups in the blood and are dangerous when in excess of. Eventually, glucose are secreted by the body through urinating which also causes kidney disorders which is a serious complication to diabetes.
