Macromolecules

Macromolecules are large molecules made up of smaller molecules joined together. The four main groups are proteins, lipids, carbohydrates and nucleic acids. They are essentially for proper cellular functioning.

What is plus DNA and minus DNA?

If we are talking about viruses and their RNA genomes(eg:HIV), the negative strand DNA synthesis by reverse transcriptase occurs in the host cells, when the virus infects the host. And then, plus DNA formed by complementing this minus DNA.

What are the 4 types of macromolecules and their primary functions?

The Four Macromolecules include Carbohydrate, Lipids, Nucleic acid, and Protein.

Carbohydrate are

Any of a group of organic compounds that includes sugars, starches, celluloses, and gums and serves as a major energy source in the diet of animals; they are produced by photosynthetic plants and contain only carbon, hydrogen, and oxygen, usually in the ratio.

Lipids:

Any of a group of organic compounds, including the fats, oils, waxes, sterols, and triglycerides, that are insoluble in water but soluble in nonpolar organic solvents, are oily to the touch, and together with carbohydrates and proteins constitute the principal structural material of living cells.

Nucleic acid: Any of a group of complex compounds found in all living cells and viruses, composed of purines, pyrimidines, carbohydrates, and phosphoric acid. Nucleic acids in the form of DNA and RNA control cellular function and heredity.

Protein: Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of chains of alpha-amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary to the functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.

Is glycogen a macromolecule?

Yes. It is a functional carbohydrate that is used as an energy storage compound in animals. When marathon runners hit "the wall," they have run out of glycogen.

DNA controls what and what does DNA stand for?

DNA stands for Deoxyribo Nucleic Acid

Edit by DrBeaver:

DNA controls protein production. It is expressed through transcription and translation to form these proteins.

What is jumping DNA?

Barbara spent years of research and after a very careful study of many generation. In 1944 McClintock recognized Jumping of DNA, which refer to unstable of DNA to move around between the chromosomes. But for many years her theory was disregarded.

In 1983, the theory of jumping DNA or which is known today "Transposable" was confirmed. In 1983 McClintock was awarded The Nobel Prize in Genetics for the discovery of genetic transposition.

What is the pupose of DNA?

The main purpose of DNA is to store and retain your genetic information. DNA contains the biological information needed to construct and maintain a living organism. It contains all the information to make the enzymes needed for all the chemical reactions taking place in your body. DNA makes you who you are. It has all your heredity info, like your hair and eye color, your height, your blood type, your personality, etc. No two person's DNA is exactly the same, not even twins, and your DNA will change over time. DNA also serves as an efficient way of passing along your genetic information to your offspring.

To get information on yourself or someone else.

What type of organic macromolecule is an enzyme?

Many enzymes consist of a protein and a non-protein (called the cofactor). The proteins in enzymes are usually globular. They have tertiary structure and this type of globular protein includes immunoglobins, as well. The structures are held in place by hydrogen bonds, disulfide bridges and ionic bonds.

What is the shape of DNA?

Though shaped like a spiral ladder it consists of two helical polymers if it was to be unwound. On the outside of the ladder is phosphate and sugars, and in the middle are the bases associated in pairs, one base coming from one helical strand and one from the opposite helical strand.

What is the role of DNA polymerase DNA replication?

Catalyzes the transcription of DNA

DNA polymerases exist as dimers associated with the other necessary proteins at the replication fork and this representation is identified as the replisome. The template for the lagging strand is temporarily looped through the replisome such that the DNA polymerases are moving along both strands in the 3'---->5' direction simultaneously for short distances, up to the distance of an Okazaki fragment.

As the replication forks progresses along the template strands, the newly synthesized daughter strands and parental template strands reform a DNA double helix. Hence it is explicit that that only a small stretch of the template duplex is single-stranded at any given time.

The progression of the replication fork requires that the DNA ahead of the fork be continuously unwound. Since the eukaryotic chromosomal DNA is attached to a protein scaffold the progressive movement of the replication fork thus intruding severe torsional stress into the duplex ahead of the fork

What are the building blocks of the macromolecules?

They are called monomeric sub-units.AnswerMacromolecules of a living organism are usually divided into four categories:

1. Lipids (or fats)

2. Proteins

3. Carbohydrates

4. Nucleic acids

There are two basic building blocks to every glyceride molecule:

at least two fatty acid chains and a glycerol molecule.

For proteins, the basic subunits are amino acids([carbon] peptide chains with an amino group attached).

For carbohydrates (things like sugars and starch and alcohols), long chains of carbon monomers form the basic structure. Functional groups like the hydroxyl group or the carbonyl group are frequently attached to the polymer chain. All sugars must have at least one carbonyl group, for example.

Nucleic acids are built with nucleotides, an essential molecule in the DNA helix.

I think what the question was asking about was actual, practical macromolecules. Such as fatty acids/lipids = FATS, carbohydrates = SUGARS, amino acids = PROTEINS, nucleic acids = DNA, RNA. Those in CAPS are the real macromolecules. Some of your macromolecules are still the base units.
