Describe the steps of protein synthesis in a eukaryote.

Answers

The first step in protein synthesis is transcription. The transcription consists of the synthesis of messenger RNA by an enzyme(RNA-polymerase). This process takes place inside the nucleus.

The second step is  translation the mRNA exits the nucleus and binds to a ribosome. Ribosomes are the sites of protein synthesis. For every three nitrogenous bases of the mRNA an amino-acid is synthesized. Amino acids are brought to the protein synthesis site by transfer RNA. From this process we are left with a polypeptide.

Transcription is the initial stage of the production of proteins. The process of transcription involves an enzyme producing messenger RNA (RNA-polymerase). The nucleus is where this process occurs.

Their bonds are mentioned as follows:

Adenosine (A) is paired with thymine (T) Cytosine (C) is paired with guanine (G)

However, the base thymine (T) is present only in the nucleotide of DNA and the base uracil (U) is present only in the nucleotide of RNA.

On February 21, a student observes that the Moon cannot be seen in the clear night sky. The date when the student is not able to see the Moon again is on March 21. The correct option is D.

What is the moon?

The moon is the only natural satellite of the earth. It is white and gray and visible from the earth on nights only. It is the fifth-largest satellite in the solar system.

The moon has different phases seen from the earth because the moon revolves around the sun. The four phases have been named full moon, no moon, C moon, and half moon.

In 28 days, the moon is not visible for one day, then the other day it is visible and C-shaped. The student was seen on February 21.

21 + 27 day means 21 march.

Amino acids are left over after proteins are digested or broken down. To help the body, the human body uses amino acids to make proteins: Food should be broken down.

A codon is a three-nucleotide (DNA or RNA) sequence that forms a unit of genomic information encoding a specific amino acid or signaling the end of protein synthesis (stop signals).

There are 64 different codons, 61 of which specify amino acids and three of which serve as stop signals.

B)Fusion reactions do not produce harmful radiation and transuranium nuclides.

Explanation:

___________

The benefit of utilizing fusion reactions instead of fission reactions is that the fusion reaction does not produce harmful radiation and transuranium nuclides. Thus, the correct option for this question is B.

What is meant by Fusion?

Fusion may be defined as a type of process that significantly involves the combination of two or more atoms or molecules in order to form one larger molecule. This type of reaction normally occurred in nature as compared to fission.

The process of fission involves the disintegration of numerous smaller molecules or atoms from a larger one. This creates a lot of long-lived radioactive substances in nature that are harmful to live organisms. These types of reactions are not favored by nature.

Therefore, fusion reactions do not produce harmful radiation and transuranium nuclides are the benefit of utilizing fusion reactions instead of fission reactions. Thus, the correct option for this question is B.

In shorthorn cattle, when a red bull (RR) is crossed with a white cow (WW), all the offspring are roan—a spotted, red and white color. What offspring are expected from mating a roan bull and a roan cow?

Answers

Answer:

25% red

50% roan

25% white

Explanation:

When RR (red) is crossed with WW (white), it results in roan color.

       RR (red)   x    WW (white)

              RW (roan)

Two roan individuals are then mated.

          RW    x    RW

       RR    RW    RW    WW

Offspring

1/4 RR - Red

1/2 RW - Roan

1/4 WW - White

Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.

Throughout history, kids have always participated and played in youth sports and have enjoyed it. However, lately, youth sports have become less exciting and more of a stressful experience among kids. It is becoming too much pressure to handle, puts children in danger of physical risk, and just takes too much effort. Youth sports are harming young people more than helping them. The first reason for discontinuing youth sports is that it is becoming too much pressure for kids. More specifically, too much of the pressure that fans and parents put on them to do good. It becomes a lot more stress than they can handle. Source 1 backs this up by saying that a lot of fans have teased or gotten angry at kids, and some of the parents get angry when they dont play up to par. I have seen this happen at baseball games when angry spectators decided to scream at the fielders for not making a slightly harder catch, and it is very disheartening to watch the kids think they are the problem. Youth sports also causes an emotional toll on players. Most of the less talented players are left behind in the dust, with only small, cheap, summer camps and less self-confidence in themselves, while more talented, taller, and faster players get scholarships and have a feeling of superiority. Source 2 even states that Children are playing fewer sports, and the less talented are left behind in recreational leagues with poor coaching, uneven play, and the message that they aren't good enough. Seventy percent of kids quit sports by age 13.. This shows how much more biased youth sports leagues are towards kids that are more talented and physically better than others. Overall, the stress that these leagues put on children is not worth it. The second reason for discontinuing youth sports is that it puts kids in danger of physical injury. Overuse and excessive practice can lead to serious fatigue that could impact players greatly. Even things such as too much exercises and repetitive running laps could make a kid excessively tired and exhausted, making them want to stop playing and lose interest. Also, source 1 highlights that, according to the American Academy of Pediatrics, most injuries in youth sports are caused by just overuse and too much training. This statement proves that youth sports repetitive training and overwork can have serious consequences. Injuries are also a big portion of youth sports that can have an extremely big influence on kids. Severe complications could even lead to trauma or disability, making a players mental health and physical health unwell. Source 1 supports this saying that ...These injuries--stress fractures, ruptured ligaments, and growth-plate injuries*--can be quite serious, and many can cause lifelong problems.. Injuries like these could majorly harm an athlete, and even end their career in sports. Youth sports is not as beneficial as it may seem. All in all, youth sports are harming young people. They put excessive stress on athletes, put kids in danger of physical risk, and take too much effort. Clearly, youth sports should not be allowed to continue anymore.
