How have new discoveries in molecular biology affected the way in which we classify organisms compared with the system used by Linnaeus?

It helps scientists where it allows them to time different kinds of evolutionary events, such as they can compare modern bird species than they would to estimate the age of the common ancestor of yeasts and humans More test answers on https://studyhippo.com/biology-chapter-18-knowledge-the-classification-of-living-things/

What is Molecular Biology?

Molecular Biology is a field of science that studies the structure and function of biological molecules. It includes the study of DNA, RNA, proteins, carbohydrates, enzymes and other macromolecules involved in cellular processes. Molecular Biology has a wide range of applications in biotechnology, medicine and agriculture.The principles of molecular biology are based on understanding the structure of biological molecules and how they interact with one another to form organisms. Molecular biologists use techniques such as gene cloning, PCR (polymerase chain reaction), sequencing and bioinformatics to analyze DNA sequences and genomes. They also use recombinant DNA technology to manipulate genes for research or therapeutic purposes. In addition, they can also study how various cellular processes work by studying the expression levels of genes in different tissues or organisms.Molecular biologists can also apply their knowledge to develop new drugs or treatments for diseases by working on techniques such as gene therapy or protein engineering. They can modify existing drugs or create new ones that target specific parts of cells more effectively than traditional therapies do. In addition, they can identify genetic markers associated with certain diseases so that doctors can better diagnose and treat them more accurately. Finally, molecular biologists are working on ways to use genetic engineering to produce crops that are more resistant to pests and disease while providing higher yields than traditional farming methods allow for greater food security around the world. In summary, Molecular Biology is an incredibly active field which continues to advance rapidly due its potential applications across many areas from biotechnology through medicine all the way up into agriculture – it is set to continue being at the forefront of scientific discovery for some time yet.
