Five steps bacteriophage takes to multiply?

1. Lands on bacteria and injects it's own DNA into bacteria.

2. Destroys the bacteria's DNA.

3. Commandeers the bacterias enzymes to start replication it's own DNA ind the protein of it's capsid.

4. Assembles this protein around the replicated DNA in hundreds of new bacteriophages.

5. Lyses and exits the cell, thus destroying it.

What do cannabinoid receptors do?

your body creates natural cannabinoids that bind to cannabinoid receptors in your brain, THC is a cannabinoid aswell, and bind to these receptors which is the chemicals way of entering the brain. :)

What is the percent of the daily value for nutrients?

"The % Daily Value is the percentage of a nutrient that one serving of the product contributes toward the daily recommended amount."

This is based on a 2,000 calories per day diet.

For example a food label may say 12g of fat = 18% daily value.

This means that 12 grams of fat is 18% of the total 65 grams of fat recommended per day

You can use the percentage to decide if there is a low or high amount of that particular nutrient in one serving of the product.

Low = 5% or less

High = 20% or more

Are green bananas a starch?

Certain enzymes in bananas convert starch in the banana into sugar, which is part of the ripening process and what makes the fruit sweeter and softer as it ripens. Therefore, the greener the fruit is the more starch it will contain.

Are Amino acids are the same except for their R group?

No, amino acids are unique in that they have the same basic structure with an amino group, a carboxyl group, and a hydrogen atom attached to a central carbon atom, but differ in their side chain or R group, which gives each amino acid its specific properties and characteristics.

What is the standard test for CO2?

The standard test for measuring CO2 levels in the blood is called arterial blood gas (ABG) analysis. This test involves collecting a sample of arterial blood, usually from the radial artery in the wrist, and analyzing it for various parameters including CO2 levels. ABG analysis provides important information on the body's acid-base balance and respiratory function.

3 reasons why the osazone test can be used in identification of sugars?

  1. The osazone test can help identify the specific type of sugar present in a sample by forming distinct crystals with characteristic shapes and colors.
  2. It is a simple and reliable method that can distinguish between different sugars based on their unique osazone derivatives.
  3. The test is sensitive and can detect even small amounts of sugars, making it useful in various applications such as food science and biochemistry.

Equations involved in the formation of fructosazone?

fructose + H2NNHC6H5----> fructose phenylhydrazone +H2O ------------>

H2NNHC6H5

2-Ketofructohydrazone + NH3 + C6H6NH ---------------> fructosazone + H2O

H2NNHC6H5

What three items form a nucleotide?

Each nitrogenous is made up of simple sugar,a phosphate group, and a nitrogenous

What makes up chitin in tubeworms?

Chitin in tubeworms is composed of long chains of β-(1,4)-linked N-acetylglucosamine (GlcNAc) molecules. These chains are organized in a complex structure that provides strength and support to the tubeworm's tube. Chitin is a tough and durable polysaccharide that is commonly found in the exoskeletons of arthropods and cell walls of fungi.

Biologist can compare amino-acid sequence of the same protein from two or more species sequences can be very similar or very different what do the similarities and differences tell us?

Similarities in amino acid sequences tell us the the genes coding for these proteins are similar. Similar genes are due to shared ancestry ie the organisms have evolved from a common ancestor in the past.

Differences in amino acid sequence tell us that mutations have occurred in the genes since the organisms separated from the common ancestor. The bigger the differences, the longer the organisms have been separated.

What is the importance of colloids in chemistry?

The importance of colloid is important especially in chemistry industry. It is also known as the 'fourth state of matter' which can be combined with the 3 major state of matters( solid, liquid and gas).

What is an example of simple protein?

SSome scientists call protein a small peptides, that is, molecules with less than 25 amino acids. However, a typical small and very important protein is the insulin. This protein is crucial for the metabolism to regulate glucose in blood stream. Insulin is formed by two amino acid chains called A chain (21 residues) and B chain (30 residues), with small variants within mammal species.

Which type of hormone requires a second messenger?

Peptide or protein hormones require a second messenger to transmit their signal inside the cell. Upon binding to their receptor on the cell surface, these hormones activate intracellular signaling pathways that use second messengers like cAMP or Ca2+ to propagate the signal and elicit a cellular response.

Is glycine essential or nonessential?

Glycine is a nonessential amino acid, which means that the body can produce it on its own and it is not required to be obtained from the diet.

Regulation of gene expression in eukaryotes?

  • mutations
  • transcrtiption factors
  • repressors
  • operons
  • which is it your pick but
  • i out mutations for this
  • one maybe im wrong
  • who knows?

What are enzyme reactors?

An apparatus, such as a large fermentation chamber, for growing organisms such as bacteria or yeast that are used in the biotechnological production of substances such as pharmaceuticals, antibodies, or vaccines, or for the bioconversion of organic waste.

What substances need a protein?

Proteins are essential for the body to function properly. Many substances require proteins for their production, such as enzymes, hormones, antibodies, and structural components like collagen. Additionally, proteins are needed for transport and signaling within the body.

What does precipitation of protein mean?

Precipitation of protein refers to the process of proteins becoming insoluble and forming solid particles within a solution. This can be induced by changes in temperature, pH, or addition of specific chemicals, leading to the formation of a cloudy or solid material that can be separated from the liquid portion of the solution.

What is the abundant molecule found in the human body?

Water (H20) and Carbon, for the most part, but there's also traces of other smaller minerals, such as calcium and magnesium.

Why is the structure of a phospholipid so important to the cell?

The structure of a phospholipid, with hydrophilic heads and hydrophobic tails, allows them to form lipid bilayers that make up cell membranes. This structure provides a selective barrier that regulates the passage of substances in and out of the cell, ensuring cellular integrity and function.

Why o-toluidine method cannot be used for the detection of fructose in a solution?

The o-toluidine method is specific to detecting glucose because o-toluidine reacts specifically with aldehyde functional groups on glucose molecules. Fructose does not have an aldehyde functional group, so it will not react with o-toluidine in the same way as glucose, making this method ineffective for detecting fructose in a solution.
