Why do scientists study proteins to find evidence for evolution?
Scientists study proteins to find evidence for evolution because proteins are essential molecules that carry out many functions in living organisms. By comparing the sequences of proteins across different species, scientists can uncover similarities and differences that provide clues about how different species are related and have evolved over time. This can help shed light on the evolutionary history and relationships between species.
What are the key differences between integral membrane proteins and peripheral membrane proteins in terms of their structure and function within the cell membrane?
Integral membrane proteins are embedded within the lipid bilayer of the cell membrane, while peripheral membrane proteins are only temporarily associated with the membrane. Integral membrane proteins have hydrophobic regions that interact with the lipid bilayer, while peripheral membrane proteins do not penetrate the lipid bilayer. In terms of function, integral membrane proteins are involved in transport, signaling, and cell adhesion, while peripheral membrane proteins often serve as enzymes or participate in cell signaling pathways.
Which of the following are responsible for the differences between species and for differences between individuals in the same population?
Genetic variations, which arise from mutations and recombination of genetic material during reproduction, are responsible for the differences between species and between individuals in the same population. These variations can lead to differences in physical traits, behaviors, and other characteristics among organisms. Additionally, environmental factors can influence the expression of these genetic differences, leading to further diversity within and between populations.
What are the key differences between FPLC and HPLC, and how do these differences impact their respective applications in chromatography?
FPLC (fast protein liquid chromatography) and HPLC (high-performance liquid chromatography) are both chromatography techniques used to separate and analyze compounds. The key differences lie in their intended applications and the types of samples they are best suited for. FPLC is primarily used for purifying proteins and other biomolecules, while HPLC is more versatile and can be used for a wider range of compounds including small molecules, peptides, and proteins. FPLC typically operates at lower pressures and flow rates compared to HPLC, making it gentler on biomolecules. These differences impact their applications in chromatography by determining which type of sample each technique is best suited for. FPLC is ideal for purifying proteins and biomolecules, while HPLC is better suited for a broader range of compounds. The choice between FPLC and HPLC depends on the specific requirements of the experiment and the nature of the sample being analyzed.
What are the structural differences between the N-terminus and C-terminus of a protein?
The N-terminus of a protein is where the amino acid chain starts, while the C-terminus is where it ends. The N-terminus has a free amino group, while the C-terminus has a free carboxyl group. These differences in chemical structure affect how proteins fold and function.
What is the differences between a chromosome and a DNA molecules?
Somewhat the difference between a brick and a brick wall. Chromosomes are made up of DNA molecules collected in units called genes ( leaving all else aside ) with attendant proteins, such as the histone proteins DNA wraps around.
What are some of the differences between the ways white blood cells and proteins fight infections?
white blood cell fight of colds dealing with the emune sistem and proteins fight for the bones and skin that works together with our white cells .

What is the fundamental basis for the differences between large carbohydrates proteins and nucleic acids?
The fundamental basis for the differences between large carbohydrates, proteins, and nucleic acids lies in their monomeric units and structural functions. Carbohydrates are primarily composed of sugar molecules (monosaccharides) that provide energy and structural support. Proteins are formed from amino acids, which determine their diverse functions in catalysis, transport, and structure. Nucleic acids, such as DNA and RNA, are made up of nucleotides and serve as the genetic blueprint for organisms, encoding and transmitting genetic information.
