Regulatory sequenceA regulatory sequence is a segment of a nucleic acid molecule which is capable of increasing or decreasing the expression of specific genes within an organism. Regulation of gene expression is an essential feature of all living organisms and viruses. In DNA, regulation of gene expression normally happens at the level of RNA biosynthesis (transcription). It is accomplished through the sequence-specific binding of proteins (transcription factors) that activate or inhibit transcription.
Brain tumorA brain tumor occurs when abnormal cells form within the brain. There are two main types of tumors: malignant tumors and benign (non-cancerous) tumors. These can be further classified as primary tumors, which start within the brain, and secondary tumors, which most commonly have spread from tumors located outside the brain, known as brain metastasis tumors. All types of brain tumors may produce symptoms that vary depending on the size of the tumor and the part of the brain that is involved.
Ethical consumerismEthical consumerism (alternatively called ethical consumption, ethical purchasing, moral purchasing, ethical sourcing, or ethical shopping and also associated with sustainable and green consumerism) is a type of consumer activism based on the concept of dollar voting. People practice it by buying ethically made products that support small-scale manufacturers or local artisans and protect animals and the environment, while boycotting products that exploit children as workers, are tested on animals, or damage the environment.
Play therapyPlay therapy refers to a range of methods of capitalising on children's natural urge to explore and harnessing it to meet and respond to the developmental and later also their mental health needs. It is also used for forensic or psychological assessment purposes where the individual is too young or too traumatised to give a verbal account of adverse, abusive or potentially criminal circumstances in their life. Play therapy is extensively acknowledged by specialists as an effective intervention in complementing children's personal and inter-personal development.
