Organisms such as fungi and algae switch to sexual mode of reproduction during adverse conditions because sexual reproduction brings variation into the individuals, some of which might help the individuals to adapt to the changed conditions and survive. This ensures the continuity of species.

By the process known as haploid parthenogenesis. Here the fertilised egg become females while the unfertilised egg will develop into male .the unfertilised egg has only half the number of chromosomes of a fertilised egg.

Enzyme-replacement therapy is effective in most patients with ADA deficiency but often fails to sustain lymphocyte counts and T-cell function. We found that ADA gene therapy improves immune function in patients who had insufficient immune reconstitution during PEG-ADA therapy. By using a unique type of gene therapy vector and treatment process, St. ... This genetic mutation affects white blood cells, mainly T cells, B cells and NK cells. These cells help the body fight off infections and protect against bacteria and other invaders. Adenosine deaminase deficiency is caused by mutations in the ADA gene. This gene provides instructions for producing the enzyme adenosine deaminase. This enzyme is found throughout the body but is most active in specialized white blood cells called lymphocytes.

RNA interference (RNAi) is a biological process in which RNA molecules inhibit gene expression or translation, by neutralizing targeted mRNA molecules. RNAi is widely used by researchers to silence genes in order to learn something about their function. siRNAs can be designed to match any gene, can be manufactured cheaply, and can be readily administered to cells. RNA interferenceRNA interference (RNAi) is a genetic regulatory system that functions to silence the activity of specific genes. RNAi occurs naturally, through the production of nuclear-encoded pre-microRNA (pre-miRNA), and can be induced experimentally, using short segments of synthetic double-stranded RNA (dsRNA).

Transcription is the synthesis of RNA from a DNA template where the code in the DNA is converted into a complementary RNA code. Translation is the synthesis of a protein from an mRNA template where the code in the mRNA is converted into an amino acid sequence in a protein. Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). ... The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation. Translation components include mRNA, small and large ribosomal subunits, initiation factors, elongation factors and tRNA. In transcription, a DNA double helix is denatured to allow the enzyme to access the template strand. In translation, no such denaturing is necessary, as the template is a single mRNA strand.

tRNA is called an adapter molecule because it attaches itself via initiation and elongation factors to the ribosome- mRNA complex which facilitates the incorporation of the correct amino acid to the growing polypeptide chain by its specific anticodon to the mRNA codon. tRNA is an adaptor molecule. ... tRNA is charged by attaching an amino acid at one end. It then binds the ribosome-mRNA complex at the position defined by a codon that codes for an amino acid. So, the tRNA molecule acts as an adaptor because it converts mRNA into proteins by the process of translation.

In men, LH stimulates testosterone production from the interstitial cells of the testes (Leydig cells). FSH stimulates testicular growth and enhances the production of an androgen-binding protein by the Sertoli cells, which are a component of the testicular tubule necessary for sustaining the maturing sperm cell. FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body. FSH and luteinizing hormone (LH) work together in the reproductive system. In males, LH stimulates testosterone release by the Leydig cells of the testes. In females, LH stimulates steroid release from the ovaries, ovulation, and the release of progesterone after ovulation by the corpus luteum
