The symptoms given may be a manifestation of Polycystic Ovary Syndrome (PCOS), which is a common endocrine system disease among females.

Symptoms are the following:

<span>1. </span>Menstrual disorders: oligomenorrhea (irregular period) or amenorrhea (cessation of period), which start around the time of the first period (menarche)

<span>2. </span>Infertility: which results from anovulation (ovaries are unable to release an egg cell during ovulation)

<span>3. </span>Obesity: at least 40% of females with PCOS are obese

<span>4. </span>Hirsutism (excessive body hair where hair is usually minimal or absent): big amount of masculinizing hormones in women with PCOS may cause hirsutism

Rus_ich [418]

Answer:

Anabolic.

Explanation:

The metabolic reactions of the body are important to maintain the physiology and homeostasis of the body. Two main types of reaction in the body are catabolic reactions and anabolic reactions.

The anabolic reaction is the reactions that are involved in the formation of the large molecules from the simpler substances. The anabolic reactions are involved in the growth and repair process as complex protein and factors are required that can only be obtained by the anabolic reactions.

Thus, the correct answer is option (3).

Copying of the information in dna into rna, which can exit the nucleus is called
Oksi-84 [34.3K]
Definition:
                 "Copying of information from DNA to RNA which exit nucleus is                                                         known as transcription"

Explanation:

                    Transcription is a vital process for living organisms, because it is a staring point for protein synthesis. It occurs inside the nucleus and is carried out by RNA polymerase enzyme. In eukaryotes RNA pol is of three types: these are RNA Pol 1, RNA Pol 2, and RNA Pol 3. In prokaryotes it is of only one type.

Steps in transcription:
                                     Transcription consists of three main steps
1. Initiation:
                   In this step RNA pol attach to DNA template at 5 prime end in the promoter region to start the formation of complementary strand of RNA.  In prokaryotes there is a region called <span>Pribnow box, with the </span>consensus sequence<span> TATAAT present about 10 base pair away from site that serves as a transcription initiation. In eukaryotes the promoter region is more complex it contain activator and enhancer.

2. Strand elongation:
                                   </span><span>Once transcription is initiated, the DNA double helix unwinds and RNA polymerase reads the template strand, adding nucleotides to the 3′ end of the growing chain.
</span>
3. Transcription Termination:
                                                T
erminator sequences are found close to the ends of non-coding sequences. Before termination polyadenylation occurs.  <span>
