Transcription factors that bind to the promoter sequences Mediator proteins - binds to enhancer and promoter regions in the gene.What is transcription of a gene?Transcription of a gene is the process by which the information present in the gene is used to produce the messenger RNA molecule by RNA polymerase.
A gene is a sequence in the DNA molecule which codes for a particular gene product.
The process of transcription is important or the first step which is required in the production of the gene product of a gene.
In order for transcription of a gene to be initiated, certain components are required. These components include:
Transcription factors - these are proteins that bind to the promoter sequences as well as other regulatory sequences in the gene. The binding of transcription factors helps to recruit RNA polymerase to the site for transcription to begin.Mediator proteins - these are proteins which form part of the RNA polymerase complex.

Megha fractured her leg while playing. Doctor plastered her leg and advised her to take calcium tablets and milk regularly. He also asked her to get plenty of sunlight. Why did the doctor asked Megha to take calcium tablets? Why did the doctor ask Megha to get plenty of sunlight?
The doctor informed her that because the bones in her legs tend to deteriorate and fracture, she should take calcium and vitamin D supplements to strengthen her bones.
A shattered bone occurs frequently. The bone can repair itself given enough time and the appropriate care. To keep the arm or leg fracture in place while the bone heals, a plaster cast is put. You are urged to visit a doctor the following day to ensure the plaster is fitted appropriately once it has been put.
Plaster casts typically are worn for six weeks. Depending on your age, general health, and the type of fracture, this period may be either longer or shorter. X-rays are taken throughout this time to make sure the bone is mending properly. You might be sent to an orthopedic surgeon if there are issues with the type of fracture or the manner the fracture is healing (bone doctor).

What is DNA ?DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

The adaptive advantage of a fungus producing and secreting a bacterial inhibitor would be that it protects against microbial competitors: is an extensive surface area well suited for invasive growth and absorptive nutrition.
Fungus
A fungus is any eukaryotic organism that includes microbes like yeasts and moulds, as well as the more recognisable mushrooms. These organisms are classed as a kingdom distinct from the other eukaryotic kingdoms, which include Plantae, Animalia, Protozoa, and Chromista in one traditional taxonomy.
The presence of chitin in fungi's cell walls distinguishes them from plants, bacteria, and some protists. Fungi, like animals, are heterotrophs; they obtain nourishment by absorbing dissolved molecules, usually by secreting digestive enzymes into their surroundings.
Fungi, like plants, use chemical defence, which involves the creation of poisons that affect the growth, development, or viability of the antagonists.

8 4 Fig. 8.1 shows a plant shoot responding to directional light. light Fig. 8.1 (a) Name the hormone which causes the response in Fig. 8.1.
The hormone which causes the shoot to respond to directional light is auxin.
Phototropism is the process by which plants respond to light by growing toward or away from a light source. Growing toward a light source is known as positive phototropism, whereas growing away from light is known as negative phototropism.
In general, the above-ground or shoot portions of plants exhibit positive phototropism or bending toward the light. This reaction assists the plant's green portions in moving toward a source of light energy, which may subsequently be utilized for photosynthesis. On the other hand, roots will often develop away from light.
The primary photoreceptors involved in phototropism are proteins referred to as phototropin. In response to phototropin activation, auxin, a plant hormone, is carried unequally along the two sides of the coleoptile. Auxin encourages cell elongation, which makes the plant grow more on the shaded side and bend toward the light source.
