g Sickle-cell anemia arises from a mutation in the gene for the beta chain of human hemoglobin. The change from a GAG to a GTG in the mutant eliminates a cleavage site for the restriction enzyme MstII, which recognizes the target sequence CCTGAGG. These findings form the basis of a diagnostic test for

Answers

Answer 1

Answer:

The sickle-cell gene.

Explanation:

The sickle cell mutation is in the gene encoding the β subunit. The sickle cell gene is located on the short arm (p) of chromosome 11, at position 15.5. Sickle cell anemia is a genopathy caused by a single mutation that results in the substitution of an amino acid in the β chains of the tetrameric protein hemoglobin. It characterized by the presence of sickle cells in the bloodstream, which are red cells or sickle-shaped erythrocytes. This form causes difficulty in the circulation of red blood cells. Confirmation of sickle cell anemia is obtained through tests that determine the presence and relative amount of hemoglobin S in a blood sample, that is, by checking the phenomenon of sickle cell disease, in a drop of blood between the slide and covers objects, or the presence of hemoglobin S by means of electrophoresis.

An inherited characteristic that allows an organism to better survive is called a(n)–
a. mutation.
b. recombination.
c. adaptation.
d. evolution.

Answers

Answer:

Its adaptation

Explanation:

An inherited characteristic that allows an organism to better survive is called an adaptation. Thus, the correct option for this question is C.

What do you mean by Inheritance?

Inheritance may be defined as a type of biological process through which traits or characters are transferred from one generation to another. It is also known as heredity.

According to the context of this question, the mechanism of adaptation involves an action of modification of an organism or its parts that significantly makes it more fit for existence or survival. This process of adaptation is passed from generation to generation, i.e. inherited from parents to offspring.

Therefore, an adaptation is an inherited characteristic that allows an organism to better survive. Thus, the correct option for this question is C.

What are the sub-phases of interphase and what occurs in each phase?

Answers

Answer:

Phases: G1, S phase and G2

Functions:

- G1: cell grows

- S phase: DNA replication

- G1: organelle replication and increase of the cytoplasmatic proteins

Explanation:

Interphase is the phase of the cell cycle in which the cell prepares for its division and ensures that each daughter cell has the correct required materials for cell survival (i.e., a correct amount of DNA, organelles, proteins, etc). Interphase can be divided into three subphases: Gap 1 (G1), Synthesis (S), and Gap 2 (G2). During G1 phase, the cell increases its size and replicates its organelles as necessary. During S phase, the cell growth continues, the DNA of the cell is replicated and rapidly assembled into chromatin. During G2 phase, the cell increases its cytoplasmatic content producing molecules it still needs to divide (e.g., essential M-cyclin molecules) and replicates its organelles (e.g., mitochondria in animals and chloroplasts in plants).

Examine the photographs of 16 species of anole lizards and sort them into as many groups as you want according to how they appear in the photographs. Explain how you grouped the lizards and your rationale for the various groupings. If you picked a body feature, speculate about the advantages or disadvantages of such a body feature in the environment that species occupies.

Answers

Answer:

On the basis of physical appearance.

Explanation:

We grouped the lizards into various groups on the basis of similarities and differences in the body structure, appearance and colour etc. The legs of anole lizards are small legs with pads on their feet for gripping surfaces which give them the advantage to climb up the trees while on the other hand, these small legs can't help in the survival on the land because they can't run too fast from their predators with these short legs so these legs has benefit in climbing the tree but disadvantage in running on the land.

Answers

Answer:

La reproducción sexual consisten en la unión de dos gametos uno femenino y otro masculino, para formar un nuevo individuo con características provenientes de ambos progenitores. Los gametos son células especializadas que se forman por un proceso meiótico y tienen en su núcleo la mitad de la información genética de un organismo, por lo que reciben el nombre de células haploides de manera que cuando se une sus cromosomas se forman células diploides característico de la especie. La característica más importante de este tipo de reproducción es la variación genética que implica que los descendientes tengan características de sus dos progenitores, por lo que son diferentes a ellos. El proceso en el que se une las células sexuales se le conoce como fecundación. En los animales esta pude ser interna o externa.

Explanation:

Los gametos (óvulos y espermatozoides) son células germinales especializadas que se desarrollan a partir de un proceso llamado gametogénesis (espermatogénesis en machos y ovogénesis en hembras). El proceso de gametogénesis implica un tipo de división celular llamado 'meiosis' donde la cantidad de cromosomas se reduce a la mitad. En humanos, el número cromosómico diploide (2n) de 46 cromosomas se reduce a un número haploide (n) de 23 cromosomas. La fecundación es el proceso por el cual los gametos se fusionan durante la reproducción sexual para producir un cigoto diploide. En la reproducción sexual, el aumento de la variación genética en la progenie es un resultado de tres procesos diferentes: la unión aleatoria entre gametos durante la fecundación, la distribución independiente de los cromosomas durante la gametogénesis y el entrecruzamiento (recombinación o crossing over) entre cromátidas de cromosomas homólogos durante la meiosis. Finalmente, en animales, la fecundación puede ser interna, la cual se produce mediante la unión de los gametos dentro del cuerpo de la hembra (por ejemplo, gallina, leona, cebra, etc.), o fecundación externa, donde la fusión de gametos se produce en el ambiente externo (por ejemplo en peces, sapos, ranas, etc.).
