How far away is Pluto from the Sun?

The image shows the transcription process in which mRNA is being synthesized. DNA double strands open in the transcription bubble and RNA polymerase acts there to add the correct nucleotides.

<h3>What is transcription?</h3>

In protein synthesis, the first step is to synthesize messenger RNA, mRNA.

Transcription is the coping process of the DNA section, occurs inside the nucleus membrane, and uses fragments of DNA molecules to do it.

During transcription, the DNI molecule separates into two strands to form the transcription bubble. At this point, two strands can identify, the coding strand and the template strand.

The coding strand goes in direction 5' to 3' and carries the same nucleotides as mRNA, except for thymine which is replaced by uracyl in the RNA molecule.

The template -complementary- DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.

While growing, the mRNA strand complements the DNA template strand. Bases complementation is as follows,

Adenine pairs DNA Thymine
Uracyl pairs DNA Adenine
Guanine pairs Cytosine
Cytosine pairs Guanine

The enzyme RNA polymerase reads the original DNI strand to add the correct nucleotides during mRNA synthesis.

Once transcription is over, mRNA moves to the cytoplasm to begin the translation process.

In the image we can see

1) the DNA molecule at the left. We can differenciate the template strand from the coding one.

2) the transcription bubble and RNA polymerase acting there.

3) Growing mRNA which complements the template strand

4) Available free nucleotides which are added to the polymere

Although E. coli may have translated it correctly, it might not have the same enzymatic<span> modification process present in the original organism where the genetic sequence was taken from. It might be worth trying this enzymatic modification, also called p</span><span>ost-translational modification - it is done in order to make some changes to the produced protein (such as introducing a phosphate group) making it functional.</span>

Do male or female songbirds build the nest? please show source and evidence to support your answer

hjlf

Actually it is the females the mostly build the nests the males will help build it sometimes both males and females will build it but typically it is females and that goes for all birds.

"Females typically build nests, but sometimes both parents or just the male"

Most of the energy that your brain uses comes from

evablogger [386]

Answer:

Glucose

Explanation:

The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.

Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.

Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.

The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.

Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.
