Is Protein Formation a Continuous Process? Do you think that our body continuously synthesizes proteins? No, proteins are not made continuously in the cells. They are made only when they are needed in the cell for cellular functions. The mRNA that codes for any protein has a stop codon which results in the termination of protein chain …
Euchromatin and Heterochromatin Are the two terms – Heterochromatin and Euchromatin confusing? If yes, we will clear the confusion here. Heterochromatin and euchromatin are two major categories of chromatin structure. Heterochromatin has condensed chromatin structure and hence appears dark during staining process. It is inactive for transcription. On the other hand, euchromatin has loose chromatin structure and appears light during staining. It is active for transcription. To get more …

Leading and lagging strands Tell me students as the name suggests, is lagging strand formed behind the leading strand? No, this is not the case. The leading strand is the strand of nascent DNA which is synthesized in the same direction as the growing replication fork. The synthesis of leading strand is continuous. The lagging strand, on the other hand, …

Nucleotides and Nucleosides Nucleotides are said to be the building blocks of nucleic acids. What are Nucleosides then? Are the two components same? Or is there some difference between them? Yes, they are different. The main difference lies in their molecular composition. Nucleosides contain only pentose sugar and a base whereas Nucleotides contain pentose sugar, base and a phosphate group as well. Let us clear this …

Template strand and Coding strand Sometimes when we are asked for the difference between the above two terms, we tend to get confused. But not any more. Let us clear this confusion now. One strand, the template strand, serves as a template for synthesis of a complementary RNA transcript. The other strand, the coding strand, …

DNA and RNA The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar, a phosphate group and a nitrogen base. DNA provides the code for the cellular activities, while RNA helps to converts that code into proteins to carry out cellular functions. …

Applications of DNA Fingerprinting This technique is used to: Identify criminals in forensic laboratories. Settle paternity disputes. Verify whether a hopeful immigrant is really a close relative of an already established resident. Identify racial groups to rewrite biological evolution.
DNA Fingerprinting Alec Jeffreys et al (1985) developed the procedure of genetic analysis and forensic medicine, called DNA fingerprinting. Of the total base sequence present in humans, 99.9% in all human beings are identical. The remaining 0.1% differs from person to person and makes every individual unique. DNA fingerprinting involves identifying the difference between two DNA molecules at the specific …
