Proteins are important food nutrients. A technician working at a food company is interested in the nutritional content of seeds/
Vladimir79 [104]

Answer: Sample 1 then, has more variety of proteins but less quantity of each one, while sample 2 has less variety but more quantity of the two proteins present.

Explanation:

Proteins are molecules found in the cells of all living organisms. A protein is composed of monomers called amino acids linked together by peptide bonds. To analyze proteins, a technique called SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) is used. <u>This technique is used to separate proteins according to their electrophoretic mobility, depending on polypeptide chain length, molecular mass, post-translational modifications and other factors</u>. SDS (sodium dodecylsulfate) is an anionic surfactant compound that breaks non-covalent bonds in proteins, denatures them causing these protein molecules to lose their native conformation and provides the polypeptide with a negative charge that is proportional to the chain length (the number of amino acids) and, therefore, to the molecular mass of the protein. The electrostatic repulsion created by the binding of SDS to the protein is one of the causes of the protein losing its native conformation, thus eliminating the differences in conformation of the different proteins to be separated in the gel.

An electric current is applied to the gel where the proteins are seeded, causing the negatively charged proteins to migrate through the gel in the direction of the anode (positively charged region). Short proteins will move more easily and faster through the pores of the gel, while larger proteins will find it more difficult to do so. After a certain time, the proteins will have migrated according to their size (measured in kDa or kiloDaltons). After electrophoresis, the gel should be stained with Coomassie blue or silver stain, allowing visualization of the separated proteins. After staining, the different proteins will appear as distinct bands on the gel. In addition, the higher the amount of a protein, the more intense the color of its band will be.

Extract No. 1 shows three bands: 25, 30 and 35 kDa. <u>This means that it has three different proteins</u>, each with a different molecular weight. Extract number 2 shows two bands: 25 and 35 kDa. <u>It means that this sample has only 2 proteins. And being bands of higher intensity, we can say that there is more of each protein.</u>

Sample 1 then, has more variety of proteins but less quantity of each one, while sample 2 has less variety but more quantity of the two proteins present.

What is a telomere? What happens to telomeres each time DNA is replicated? How do cells prevent this from occurring?
vredina [299]
Telomeres are protective sequences of nucleotides found at the ends of chromosomes,Which become shorter every time a cell divides.
A gradual degeneration of an organism occurs, resulting in ageing.
However, some cells are able to replenish their telomeres using the enzyme telomerase. 
Hope this helps! :)

Drag labels to the appropriate locations in this diagram.
Vinil7 [7]

Answer:

c = Enzymatic activity

e = Attachment to ECM and cytoskeleton

f = Signal reception and relay

g = Transport

h = Intercellular junctions

i = Cell-cell recognition

a = Phospholipid bilayer

b = Fibers of extracellular matrix (ECM)

d = Microfilaments of cytoskeletons

Explanation:

c) Enzymatic activity is an indication of the amount of active enzymes present to increase a reaction rate

e) Attachment to ECM and cytoskeleton is enabled by integrins that take signals from the ECM and control signaling pathways of the cell

f) Signal reception and relay is the transduction of signal

g) Transport is the movement of matter in and out of the cell through the cell membrane

h) Intercellular junctions are the contact regions between adjacent cells and plasma membrane

i) Cell-cell recognition is power of the cell to decipher the different neighboring cells in the cell's environment

a) Phospholipid bilayer consists of a hydrophobic interior and a hydrophilic exterior

b) Fibers of extracellular matrix (ECM) are ECM associated the cell

d) Microfilaments of cytoskeletons consist of actin and aid in cellular movement.
