protein synthesis serves as a method to produce proteins for the body. The process occurs in a few stages. First, the genetic code is copied from DNA in the nucleus to a molecule called mRNA. Then, transcription and translation will occur and with the help of aribosome, a protein is ...
The second type of RNA istransfer RNA(tRNA). This is a smaller nucleic acid molecule and comes in 20 subtypes, one for each amino acid. Its purpose it to shuttle its "assigned" amino acid to the site of translation on the ribosome so that it can be added to the growing polypeptide (...
3. Draw a labelled diagram to show how four nucleotides are joined together to form a double-stranded DNA molecule with two base pairs. [3 marks] 4. State two differences between RNA and DNA nucleotides. [2 marks] Reference: Clegg, C. Biology for the IB Diploma (2nd ed.). Hodder Educ...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Every protein that was detected was included regardless of how low the expression counts were, with the exception of highly polymorphic proteins such as HLA-A. Second, we added all proteins with a designated CD number as of the 10th human cell differentiation molecule workshop56. The amino ...
In this paper, we introduce a new method of modeling tool for a biological process - central dogma. The data-flow diagram is used as a representation of the whole data input and output, which enables us to simulate, analyze, and manipulate (in the future) at our disposal. From DNA to ...
There is a question of how a spatial polygonal arc in 3-space such as a linear molecule, a protein, a non-circular DNA, or a linear polymer, etc. is considered as a knot object. This paper answers it by introducing a notion of knotting probability of a spatial arc. As a tool, ...
Stages of Aerobic Respiration Stage 1: Glycolysis Aerobic cellular respiration starts with a process called glycolysis, which takes place in the cytoplasm of the cell. It involves the breakdown of a six-carbon glucose molecule into two pyruvate molecules, which are each a three-carbon molecule. In...
DNA consists of monomers called **nucleotides**, each of which in turn has threesubunits: a five-carbon sugar called deoxyribose, aphosphate groupand anitrogenous base. The sugar and phosphate sections of the molecule are invariant, but thenitrogenous basecomes in four types:adenine (A), cytosi...
