Description

This lecture covers the fundamental functional aspects of all living beings, focusing on the living cell as the smallest biological unit. It introduces key concepts in biochemistry and cell biology, highlighting essential sources and readings for further study. The instructor provides insights into various textbooks, such as 'Biochemistry: Concepts and Connections' and 'Brock Biology of Microorganisms', emphasizing the importance of understanding macromolecules, molecular evolution, and general metabolism. Additionally, the lecture explores the relationship between chemistry and biology, the distinctions between bacterial and animal cells, and the significance of metabolism in cellular processes.

Anna Carratala Ripolles

During my PhD, I mainly focused on characterizing the effect of environmental factors (namely temperature and sunlight) and disinfectants on the stability of human viral pathogens as contaminants of aquatic environments. In addition,I developed a novel source tracking tool to identify avian fecal contamination in environmental samples. Thanks to a research fellowship given by the Spanish Ministry of Science and Technology, I also had the opportunity to explore the diversity of marine viruses in Mediterranean coastal waters by genetic fingerprinting and by next generation sequencing. Later on, I became interested in the long-term effect of environmental stressors on virus communities, so I joined the LCE as a postdoc to investigate the adaptation of enteroviruses to ultraviolet radiation. For 4 years, I worked on developing UV-resistant viruses and characterizing their acquired phenotypic and genetic properties by combining directed evolution experiments, deep sequencing and population genetics. Out of the lab, I am passionate about nature, traveling and scuba diving.

Cell culture

Cell culture or tissue culture is the process by which cells are grown under controlled conditions, generally outside of their natural environment. The term "tissue culture" was coined by American pathologist Montrose Thomas Burrows. This technique is also called micropropagation. After the cells of interest have been isolated from living tissue, they can subsequently be maintained under carefully controlled conditions. They need to be kept at body temperature (37 °C) in an incubator.

Animal

Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. As of 2022, 2.16 million living animal species have been described—of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates—but it has been estimated there are around 7.

Biochemistry

Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research.

Cell theory

In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction. The three tenets of the cell theory are: All organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms.

Animal coloration

Animal colouration is the general appearance of an animal resulting from the reflection or emission of light from its surfaces. Some animals are brightly coloured, while others are hard to see. In some species, such as the peafowl, the male has strong patterns, conspicuous colours and is iridescent, while the female is far less visible. There are several separate reasons why animals have evolved colours. Camouflage enables an animal to remain hidden from view.
