Below is a mature eukaryotic mRNA transcript. Translate this mRNA into a protein, also showing the tRNA anticodons involved. Mak

diamong [38]

Answer:

mRNA ⇒ 5'GMU UAC AUG CGG CUC AGU UGA GGC GAA AAA A 3'

tRNA ⇒ UAC GCC GAG UCA ACU

protein ⇒ N - MET ARG LEU SER Stop - C

Explanation:

In protein synthesis, the ribosome reads mRNA in the 5´ to 3´ direction, and, according to the codons that are being readen, tRNA transfers the correct amino acids to build the polypeptide chain. A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly. Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid. tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.

Once the new amino acid links to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.

The protein is synthesized from the amino terminus to the carboxy terminus, while the added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches the end codon, protein synthesis is over.

Each of the codons represents one of the 20 amino acids used to build the protein. Each amino acid can be codified by more than one codon. From the total 64 codons, 61 codify amino acids, and one of them is a start codon. The left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule.

• The end codons are UAA, UAG, UGA.

Protein synthesis initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA.

In the exposed example we have the following mRNA.

mRNA ⇒ 5'GMU UAC AUG CGG CUC AGU UGA GGC GAA AAA A 3'

Codons are separated by a space left between them. AUG is the start codon placed near the 5´ extreme. UGA is the end codon near the 3´ extreme. tRNA will add amino acids from the start codon, not before.

tRNA ⇒ UAC GCC GAG UCA ACU

Anticodons are separated by a space left between them.

protein ⇒ N - MET ARG LEU SER Stop - C

Each mRNA codon codifies for an amino acid. The start codon codifies for methionine. AUG = Met, CGG = Arg, CUC = Leu, AGU = Ser, UGA = Stop codon. The amino terminus is represented as an N and the carboxy terminus is a C. The first extreme to be translated carries the amino-terminal group, while the other extreme carries the carboxy-terminus group.

Answer:Genetic testing involves examining your DNA, the chemical database that carries instructions for your body's functions. Genetic testing can reveal changes (mutations) in your genes that may cause illness or disease.

Although genetic testing can provide important information for diagnosing, treating and preventing illness, there are limitations. For example, if you're a healthy person, a positive result from genetic testing doesn't always mean you will develop a disease. On the other hand, in some situations, a negative result doesn't guarantee that you won't have a certain disorder.

Consider these scenarios. Scenario A: Carmen reads an article in Tasty Food magazine stating that eating an apple can help you f

sineoko [7]

Answer: The article read by Yuki is more likely to have been peer-reviewed because this article is part of a Journal Medicine and peer-review is mandatory in most Academic journals before publication.

Explanation:

Peer-review implies academic works such as research papers or articles are verified by peers of the author. For example, a medical article is evaluated by other experts in the same field with similar knowledge and competences. This process is essential to guarantee the information is accurate and reliable. Moreover, peer-review is used mainly in academic journals or academic papers. Indeed, most academic journals require new articles or papers to be peer-review before these are published in the journal.

In this context, it is likely the article red by Yuki has been peer-reviewed because this is part of a Medicine journal and it is a general standard for articles in journals to be reviewed. Also, this is not a requirement for articles published in regular magazines such as Tasty Food magazine.

Ratling [72]

Answer:

The correct option is : It undergoes a lysogenic cycle.

Explanation:

A virus can replicate inside a host cell by two process :

Lytic cycle

Lysogenic cycle

In the lytic cycle, the viral DNA makes copies of itself and manufactures the viral machinery inside the host cell. Eventually, the host cell bursts causing the release of the viruses. In such a condition the varicella virus would cause chicken pox.

In the lysogenic cycle, the DNA of a virus get incorporated into the DNA of the host. The viral DNA might replicate when conditions become favourable and cause diseases. In such a condition, the varicella virus would cause shingles.
