Assuming no crossing over between the gene in question and the centromere, during what phase of meiosis do alleles segregate?

Biology

choli [55]4 years ago

Answer:

During Anaphase stage

Explanation:

Meiosis is the type of cell division employed during gamete formation when each resulting gamete (daughter cell) has their chromosomal number reduced by half. Meiosis occurs in a two step division; Meiosis I and II. Meiosis I involves the separation of homologous chromosomes (similar but non-identical chromosomes received from each parent) while Meiosis II involves separation of sister chromatids (replicated chromosomes).

Alleles are present on the chromosomes which segregate or separate during the anaphase stage. Alleles received from each parent are separated in Anaphase I of meiosis I, which the identical replicated alleles are separated in anaphase of meiosis II.

Why are uncompetitive andmixed inhibitors generally considered to
Wittaler [7]

Answer:

The uncompetitive and mixed inhibitors are not affected by the substrate concentration while inhibition by a competitive inhibitor can be overcome by increasing the concentration of the substrate.

Explanation:

A competitive inhibitor competes with the substrate for the active site of the enzyme. When the competitive inhibitor combines with the enzyme and forms the enzyme-inhibitor complex (EI complex), the substrate cannot bind to the active site. However, the inhibition by competitive inhibitor can be overcome by increasing the substrate concentration around the enzyme which in turn would allow the substrate to bind to the active site and the reaction would proceed.  

On the other hand, an uncompetitive inhibitor binds to the site at the enzyme different from the active site. Once the ES complex is formed, the uncompetitive inhibitor joins the complex to inhibit the enzymatic activity.  

Likewise, a mixed inhibitor also occupies a site on the enzyme distinct from the active site for the substrate. A mixed inhibitor binds to the enzyme or ES complex to inhibit the reaction.  

Since the binding site for uncompetitive and mixed inhibitors are distinct from the substrate-binding site on the enzyme, increasing the substrate concentration can not overcome the inhibition.

A patient with acromegaly is prescribed bromocriptine mesylate (parlodel) therapy. which information does the nurse give to the
Tpy6a [65]

  • report watery nasal discharge to the health care provider immediately; option E

<h3>What is acromegaly?</h3>

Acromegaly is a disease condition in which there is over-secretion of the growth hormone by the pituitary gland.

Some of the symptoms of acromegaly include:

  • large, prominent facial features
  • skin changes

For a patient with acromegaly is prescribed bromocriptine mesylate (parlodel) therapy, the information the nurse should give the patient about his treatment include:
