Recent questions
What is the molecular basis of inheritance?
The molecular basis of inheritance focuses on DNA structure, replication, transcription, translation, genetic code, and the human genome project. It delves into Mendel's principles of inheritance, the discovery of DNA as genetic material, and the structure of DNA.
How does DNA differ from RNA?
DNA is deoxyribonucleic acid, while RNA serves as genetic material with various roles like messenger, adapter, structural, and enzymatic. DNA is a long polymer made up of deoxyribonucleotides, while RNA has two types of nuclei and lacks thymine present in DNA.
What is the role of nucleotides in DNA structure?
Nucleotides in DNA consist of sugar, nitrogenous base, and phosphate group, forming nucleosides and nucleotides. The structure includes pentose sugar, nitrogenous bases (purines and pyrimidines), and phosphate groups, with bonds like glycosidic bonds between sugar and base, and phosphoester bonds between sugar and phosphate.
How does transcription occur in genetic material?
Transcription involves RNA polymerase working on the template strand, starting at the promoter and stopping at the terminator. The promoter is where RNA polymerase attaches to initiate transcription, while the terminator signals the end of the process, forming new RNA based on the template strand.
What is the significance of the Human Genome Project?
The Human Genome Project aimed to determine the sequence of chemical base pairs, identify genes, understand DNA variations, diagnose diseases, and create genetic and physical maps. It involved countries worldwide and aimed to transfer genetic knowledge, address ethical issues, and potentially prevent illnesses in the future.
