have for protein synthesis? Explanation: The mRNA encodes the amino acid sequence of a protein. During the translation‚ ribosomal RNA combines with other proteins to form a ribosome which amino acids are transported to the ribosome. The combination of mRNA and tRNA converts the mRNA into the amino acid sequence of the protein. Did the two mutations result in a change in the final proteins? If so‚ describe the change. Response/ explanation: A change took place in the final proteins because

All of the answers are correct. 3) The sum

genetic information and copies itself (replication) to pass on the information • Contains genes (instructions to make proteins) • Instructs cell’s activities DNA Structure • DNA is a polymer of nucleotides • Chromosomes (DNA strand + associated proteins ie. Histones wrap DNA around like a spool = condensed chromatin) ↓ genes (sections of a chromosome that codes for a protein) ↓ nucleotides (3 parts: phosphate‚ deoxyribose sugar‚ and nitrogen base) • • • Double helix shape - Held together

question ask is‚ how big is my protein footprint? It also asks‚ does a meat rich diet have a negative impact on our environment? And does it contribute to global warming? With a very small percentage of Americans following a vegetarian diet. I will say that my protein footprint is about the same as the majority of the US population. I understand that a good source of protein can be found in nuts‚ black beans and lentils. However the number one source of protein in a US household‚ comes from

Produced by cell clusters in the pancreas called the Islets of Langerhans‚ insulin is a hormone that regulates glucose concentration in the blood. It is a protein synthesised and stored by beta cells‚ which secrete it in surges responding to changes in glucose levels. (Hardin‚ Bertoni and Kleinsmith‚ 2012) Fig 1.

can be done by protein electrophoresis. Protein electrophoresis involves the movement of proteins within an electric field with mobility being dependent on factors such as the size and shape (secondary and tertiary structure)‚ as well as the charge of the protein (due to primary structure). Other factors that can affect the mobility are electric-field strength‚ matrix pH‚ and ionic buffer strength of the electric field. Because there are so many factors involved in analyzing proteins during electrophoresis

see looking at the Total Protein column on Table 3‚ the most effective step with regard to the percent of remaining protein removed was affinity chromatography because it was able to remove 98.6% of the remaining proteins. In comparison to 81.93% removed during the 65% ammonium sulfate precipitation and 81.3% during the size exclusion. This means that the affinity chromatography removed a big percentage of contaminating proteins. However‚ removing this huge amount of protein left us with a small amount

T2:BIOCHEMISTRY AND ANALYSIS:DETECTION OF FATS‚PROTEINS AND CARBOHYDRATES OBJECTIVE The main purpose of the experiment is to understand some general tests that detect fats‚proteins and carbohydrates in foods. INTRODUCTION Carbohydrates are also known as sacharides. There are 4 main groups of carbohydrates‚which are monosaccharides‚ disaccharides‚ oligosaccharides and polysaccharides. Carbohydrates play an important role in living organism as it is the energy storage‚ and it also plays
