The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

What is a gene?‚ 2015)Genes lie in long strands of deoxyribonucleic acid (DNA) called chromosomes. DNA containing genes form structures call chromosomes. Humans have 23 pairs of chromosomes. Chromosomes are made up of a single molecule of DNA and proteins. (Medicine‚ 2015) DNA is a double-stranded molecule compose with sugar‚ phosphate and four nitrogen bases called nucleotides. They are A (Adenine)‚ C (Cytosine)‚ G (Guanine) and T (Thymine). These bases

Actin‚ a globular protein with a molecular weight of 42-kDa‚ is the most abundant intracellular protein in most eukaryotes (3). It plays important roles in many essential cell biological processes. Actin exists as a monomer called G-actin and as a filament called F-actin‚ a linear chain of G-actin subunits (2). Two F-actin filaments intertwine to form a microfilament‚ one of the three major components of cytoskeleton (2). Microfilament is important for generating cell movement. One mechanism involves

don’t interface well. The hydrophilic Asparagine would be repulsed by the hydrophobic amino acids; they would every attempt to detach the other with a specific end goal to be "upbeat". In the event that they are not cooperating‚ the strength of the protein would waver in light of the fact that the amino acids would be repulsing one another and incapacitate it from working

hotplate until near boiling. After the whey protein had precipitated‚ a vacuum filter was used to filter out the whey. These proteins were then air-dried. A qualitative test was done to indicate that the sample extracted was the protein whey. Again‚ a small test tube was used and 2 mL of protein test solution was put in the tube. Five drops of 10% NaOH and 2 drops of 0.5% CuSO4 were added to this tube. If a purple color showed‚ it would indicate there was protein in the test tube. In the third separation

information that doesn’t directly make proteins but it helps makes codes for the production of proteins‚ DNA Transcription consist of 4 nucleotide bases‚ Adenine‚ Thymine‚ Cytosine‚ Guanine. Transcription also unwinds the strand of DNA and the RNA comes in and matches then becomes a single strand. The only thing that changes during this process is the Thymine gets replaced with Uracil. TRANSLATION: Translation is the process of which RNA helps in the making of Protein‚ Translation is located in the Cytoplasm
