Developmental psychobiology posed this question since the lack of knowledge about the precise coordination of all cells, even those not related anatomically, in space and time during the embryonic period does not allow us to understand what forces at the cellular level coordinate four very general classes of tissue deformation, namely: tissue ...
Biology is the scientific study of life. [ 1 ] [ 2 ] [ 3 ] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [ 1 ] [ 2 ] [ 3 ] For instance, all organisms are composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...
Other advances in molecular biology stemming from the discovery of the DNA double helix eventually led to ways to sequence genes. James Watson directed the Human Genome Project at the National Institutes of Health. [7] The ability to sequence and manipulate DNA is now central to the biotechnology industry and modern medicine.
Paper 1 (45 raw marks contributing 30% of the course, 1 hour) consists of short-answer and data-based questions. Paper 2 (65 raw marks contributing 50% of the course, 2 hours) consists of: Section A: Candidates are required to analyse and make reasoned and balanced judgements relating to a range of data on a specific unseen case study.
NMDCAT consists of multiple choice questions. Each question carries 1 mark with no negative marking for wrong answers. Total score is 200. 68 questions are from Biology, 54 from Chemistry, 54 from Physics, 18 from English language, 6 from Logical reasoning. Only in 2021 the total score was increased to 210. The next year the score was back to 200.
The question papers are distributed by the overseeing board of education, and their contents are guarded closely until the exam begins. The examinations may include multiple sets of question papers as well. The candidates are issued identification passes in advance, which are presented to the staff at the examination site.
In bioinformatics, BLAST (basic local alignment search tool) [3] is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences.
A scientific paper documenting a new experiment conducted by the author is a primary source on the outcome of that experiment. Secondary sources provide an author's own thinking based on primary sources, generally at least one step removed from an event.
