Bsc(2nd sem ) 1st year zbc (zoology) topic gene material and RNA

Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and DNA are nucleic acids, and, along with lipids, proteins and carbohydrates, constitute the four major macromolecules essential for all known forms of life.Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared to a copy from a reference book, or a template, because it carries the same information as its DNA template but is not used for long-term storage. Each ribonucleotide base consists of a ribose sugar, a phosphate group, and a nitrogenous base. Adjacent ribose nucleotide bases are chemically attached to one another in a chain via chemical bonds called phosphodiester bonds. Unlike DNA, RNA is usually single-stranded. Additionally, RNA contains ribose sugars rather than deoxyribose sugars, which makes RNA more unstable and more prone to degradation. RNA is synthesized from DNA by an enzyme known as RNA polymerase during a process called transcription. The new RNA sequences are complementary to their DNA template, rather than being identical copies of the template. RNA is then translated into proteins by structures called ribosomes. There are three types of RNA involved in the translation process: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). And at last how is rna different form dna .

bsc zbc( 1st sem )ecology topic carbon cycle

The series of processes by which carbon compounds are inter converted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels. This process focus upon the ecological carbon cycle with it's diagram.........it's basically the second clip , first clip is that of the water cycle

Bsc (2nd semester) 1st year BOTANY-paper- biostatistics part -2

It's main focus is to concentrate upon the important topic such as measure of central tendency, mean, median and mode coming up in next clip ( it's types , merit , methodology, definition & limitations ) some of the illustration through examples with the chart construction and an add on shortcut methods . It's introduction with some of the definations given by scientists , other two parts is mode soon their picture would aslo be uploded with their defination , history , types examples and question papers . This is very important topic of biostatistics summing up with it's disruptive and discipline explanation , i can also make a video to make it understand briefly with solving examples

Nift , nid , iift entrance exam solved paper ( last paper of this sample paper )

Sample papers are important preparation material used by almost all students during revision for their board exams. Solving sample papers helps a student to understand the pattern of the question paper and the marking scheme of the board question paper.The sample paper is based on the actual question paper format which helps students in getting an overview of the paper pattern including the type of questions like short or long answer type questions, mostly asked topics, marks distribution, etcWhereas sample papers usually have more difficult questions. I wouldn't recommend a person to go through the sample paper a day or two before the exam unless he/she is super confident with the curriculum (don't try testing your confidence). Going through the previous year papers would make better sense.(i) Before solving the sample paper of a particular subject, make sure that you have covered the whole syllabus of that subject. (ii) Solve the sample papers with pen and paper just the way you do in an exam. Do not solve questions orally by applying mind calculations . Attributes of a good question paper. The question paper setter and evaluator should fulfill their assignment with great honesty, dedication, integrity and seriousness. ... A question paper is the basic tool used in an examination. Sometimes, question papers are under debate for their levels of toughness and lengthy content . Sample papers are important preparation material used by almost all students during revision for their board exams. Solving sample papers helps a student to understand the pattern of the question paper and the marking scheme of the board question paper.
