Answer:

All are used to resolve questions in molecular and biochemistry/biotechnology

Explanation:

PCR: resolution of an amplicong on agarose gel to chech size after thermocycling

DNA gel electrophoresis,

Recombinant DNA, A DNA fragment that it attached to another such as a reporter, commonly used is GFP attached to protein of interest to track movement

Cloning, Duplicate an amplicon, insert into a vector, transform this vector into a bacteria that is designed to make multiple copies of itself

Northern blots, Method used to detect different sizes RNA from a mixture of other products

Southern blots, method used to detect different sizes of DNA similar to the idea of a Northern Blot

Western blots, Resolution of protein sizes by running the protein through an acrylamide gel in an ionic buffer

Antibody production (polyclonal and monoclonal),  Generating an antigen against a protein using different parts of the same protein (polyclonal) or only a specific sequence of the protein not a variety of antigens from the full length (monoclonal)

ELISA, enzyme-linked immunosorbent assay is used to check the presence of a protein

FRET, Transmission energy of one molecule to another, it is usually included in the detection of colors in fluorescence microscopy

FRAP, this method will is called Fluorescence recovery after photobleaching, a microscospy measurement

FACS, this is a type of cell sorting Fluorescence-activated cell sorting

Fractionation by centrifugation, Lysis of agents such as cells that can be lysed by spinning in a centrifuge

Chromatography, separation of chemical thru a media by colors

Fluorescence microscopy,  use of fluorophore to detect specimen under a microscope a specific wavelength

Coomassie staining,  procedure used to stain an acrylamide gel or membrane to show protein presence

Silver staining, use of a silver colloid to change the way proteins are seen on a Western blot or under a microscope

His tag, a string of histidine residues attached to a protein for easy manipulation/detection

GST tag, Glutathione S-transferases is a group of proteins used in protein purification an option other than His tag

Confocal microscopy,

FISH, The generation of a nucleotide probe used in DNA sequence detection in histology

PCR, Polymerized chain reaction used to amplify selected region of DNA

DNA library, the collection of gDNA of a specific specie or tissue

cDNA library, collection of the coding sequence of a organism/tissue

Microarrays, the platform used to detect thousands of gene sequences at once

Sanger sequencing, Method used to derrive DNA sequence developed by Frederick Sanger by incorporating a single nucleotide at a time

GFP, Green fluorescent protein, a reporter protein used in recombination protein creation

Bright field microscopy, microscopy that uses light or natural light to detect samples

DIC microscopy, Differential interference contrast is used to detect and enhance the different levels of contrast of a specimen

Phase contrast microscopy, Microscopy technique used to detect the different states of matter of a specimen

Fluorescence microscopy, use of fluorophore attached to sample for investigation

Transmission electron microscopy, uses beams of electrons to pass through a sample to then create an image

Scanning electron microscopy,  the surface of a sample is scanned with a beam of electrons to generate an image

X ray crystallography, determining a structure of a protein my using an x-ray technique

2D PAGE electrophoresis,  separation of proteins by two phases sizes and charges

NMR,  Nuclear magnetic resonance, spinning of all the nuclei and measurement of the energy that it gives off.

Mass spectrometry Protein sequencing technique based on weight

Is plate-based or a meat-based diet is more nutritious
seropon [69]
Question: is plate-based or a meat-based diet is more nutritious

Answer: But it's also common to choose a plant-based diet because it's considered healthier. And that's for good reason. Research over many years has linked plant-based diets to lower rates of heart disease, type 2 diabetes, and some cancers (as compared with diets high in meat and other animal products

Is a meat based diet better than a plant-based diet? Answer: Mounting evidence shows that reducing meat and increasing plant-based protein is a healthier way to go. A diet with any type of meat raises the risk of heart disease and cancer, when compared with a vegetarian diet.”

Plant-based diet: A plant-based diet or a plant-rich diet is a diet consisting mostly or entirely of plant-based foods. Plant-based foods are foods derived from plants with no animal-source foods or artificial ingredients. While a plant-based diet avoids or has limited animal products, it is not necessarily vegan.

Meat based diet:

Meat is a complete, high-quality protein containing all of the essential amino acids your body needs for optimal health.


Meat provides more protein per serving (25 grams per 3 ounces) than dairy (8 grams per cup), eggs (6 grams each), legumes (12 grams per ¾ cup), vegetables or nuts (2 to 5 grams per serving).

What four characteristics of an aquatic environment might make photosynthesis or life processes difficult for aquatic plants? Li
elena55 [62]

Answer:

Hello there, I will give the answer

Explanation:

Aquatic plants require special adaptations for living submerged in water, or at the water's surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.

What statement best describes the relationship between photosynthesis and cellular respiration
Zepler [3.9K]

Answer:

Photosynthesis remove the carbon dioxide from atmosphere and release oxygen while cellular respiration release the carbon dioxide in atmosphere and consume oxygen.

Explanation:

Photosynthesis:

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

Carbon dioxide + water + energy →   glucose + oxygen

water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture  by chloroplast.

Chemical equation:

6H₂O + 6CO₂ + energy  →   C₆H₁₂O₆ + 6O₂

Cellular respiration:

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

it is the reverse of photosynthesis.

There are two types of respiration:

1. Aerobic respiration  

2. Anaerobic respiration

The Anaerobic respiration  occur in the absence of oxygen.
