If a tRNA molecule has an anticodon which reads AGGCCG, what was the codon on the mRNA molecule?

TCCGGA
UCCGGC
UCCGGU
CTTAAG

Answers

The codon is the sequence of nucleotides that carry genetic information that determines which amino acid should be added to the building protein. Nucleotides in this sequence pair with nucleotides from the tRNA  anticodon. In the exposed example, the correct codon pairing the given anticodon is is UCCGGC.

Before expplanation, let us review some theoretical frame to answer the question.

During protein synthesis, the ribosome reads mRNA in the 5´ to 3´ direction, while tRNA adds the correct amino acids to build the polypeptide, according to the codons readen in the mRNA chain. A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly. Each of the codons represents one of the 20 amino acids used to build the protein. 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 joins the growing protein, the binding between the amino acid and the tRNA breaks, releasing the molecule, which is now available to join another amino acid and repeat the cycle.  

Anticodon: Sequence of bases that pairs with the mRNA codon.  

Amino Acid: the amino acid that is codified by the mRNA codon.  

Remeber that:

Adenine forms pairs with Uracyl ⇒ A↔UGuanine pairs with Cytosine ⇒ C↔G

In the exposed example, the tRNA anticodon is AGGCCG, so we need to find its complement.

We know that Adenine pairs Uracyl, Guanine pairs Cytosine, and Cytosine pairs Guanine. So,

Anticodon → AGGCCG

     Codon → UCCGGC

Si una población crece mucho otra vez después de un cuello de botella con el paso del tiempo aumentará diversidad genética ¿por qué?

Answers

Answer:

los mecanismos capaces de generar diversidad actúan para incrementar la variabilidad genética en la población que sufrió el cuello de botella

Explanation:

Un cuello de botella se refiere a una reducción drástica en el tamaño de una población (por ejemplo, debido a una catástrofe natural). Un cuello de botella es un fenómeno que está asociado a la ​reducción en la variación genética y fijación de ciertos alelos en la población resultante, lo cual es causado por la deriva genética, es decir, debido al muestreo al azar de los individuos que formarán la población en la siguiente generación. Paulatinamente, los mecanismos capaces de generar variabilidad genética aumentarán nuevamente la diversidad de la población que sufrió el cuello de botella. En una población de reproducción sexual, la variación genética se genera mediante cuatro procesos diferentes: 1-mutación (es decir, la aparición de nuevos alelos debido a alteraciones en la secuencia de ADN); 2-recombinación (es decir, el intercambio de información genética entre cromátidas no hermanas durante la meiosis); 3-segregación independiente de cromosomas durante la meiosis (capaz de producir nuevas combinaciones de alelos) y 4-fertilización al azar (lo cual también incrementa el número de combinaciones entre gametos que darán lugar a un nuevo individuo).

Listeriosis is of particular concern for pregnant women because pregnant women are more likely than other population groups to get listeriosis. listeriosis can cause fetal death. Listeria bacteria can cross the placenta and infect the fetus. All of the choices are correct.

Answers

Answer:

The correct answer is ''All of the choices are correct.''

Explanation:

Pregnant women are a risk group for listeriosis, the disease caused by the Listeria monocytogenes bacteria found in contaminated food. This organism can cross the placenta and affect the fetus. Due to the decrease in cellular immunity, pregnant women are part of the population at risk and are 17-20 times more likely to develop listeriosis after the consumption of contaminated food and it usually occurs from the third trimester and appears as a disease mild with not very high fever, joint and muscle pain. Listeriosis can cause miscarriages during the first three months of pregnancy. As the third trimester is reached, the mother is at greater risk. It presents a 40-50% fetal or neonatal mortality. In the first or second trimester it produces septic abortions and intrauterine fetal death, in the third trimester she produces chorioamnionitis and premature labor. In 1/3 cases it can occur asymptomatically in the fetus / neonate. In newborns, listeriosis can cause blood infections and meningitis.

What is genetic engineering?

Genetic engineering (also named genetic modification) exists as a system that operates laboratory-based technologies to change the DNA makeup of an organism. This may influence changing a single base pair (A-T or C-G), deleting a region of DNA, or adding a unique element of DNA.

Genetic engineers change, splice, eliminate, and rearrange genes to change an organism or classes of organisms. Genetic engineering, also called genetic modification or genetic manipulation exists in the modification and manipulation of an organism's genes operating technology.

Genetic engineering stands performed in three fundamental steps. These exist,

(1) The isolation of DNA components from a donor organism.

(2) The insertion of an isolated donor DNA fragment into a vector genome.

(3) The effect of a recombinant vector in a suitable host.

Hence, The accurate order is,

I. Replicate the new organism.

II. Isolate the genes from the specialist cell.

III. Select the desired trait.

IV. Insert the genes into the target organism.

There are 4 phenotypes are possible from the 3 alleles coding for human blood. The correct option is B.

What is phenotype?

The set of qualities or characteristics that can be observed in an organism are known as its phenotype in genetics.

The word includes an organism's anatomy, developmental processes, physiological and biochemical characteristics, behaviour, and the outcomes of behaviour.

The genotype of an individual is their own DNA pattern. More specifically, the two alleles a person acquired for a particular gene are referred to by this phrase.

The clinical presentation of a patient is the observable expression of this genotype, or phenotype.

A, B, AB, and O are the four phenotypes of blood that can occur. The gene that determines blood type has three alleles. Six distinct genotypes are possible because there are three different alleles.

Thus, the correct option is B.

Answers

Answer:

A pearl is a hard, glistening object produced within the soft tissue (specifically the mantle) of a living shelled mollusk or another animal, such as fossil conulariids. Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite)[3] in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur. The finest quality of natural pearls have been highly valued as gemstones and objects of beauty for many centuries. Because of this, pearl has become a metaphor for something rare, fine, admirable and valuable.

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.

positive impact  

Environmental regulations have greatly improved air and water quality, especially in areas that were dirtiest before regulation. Reducing airborne particulates is especially beneficial, saving thousands of lives and preventing millions of illnesses each year.
