A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain or a DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together (Figure 4-3).

What are nucleotide subunits?

Nucleotides are composed of three subunit molecules: a nucleobase a five-carbon sugar (ribose or deoxyribose) and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine adenine cytosine and thymine in RNA uracil is used in place of thymine.

What are the 4 bases that make up the rungs of the DNA ladder?

Other combinations of the atoms form the four bases: thymine (T) adenine (A) cytosine (C) and guanine (G). These bases are the rungs of the DNA ladder. (It takes two bases to form a rung — one for each side of the ladder.) A sugar molecule a base and a phosphate molecule group together to make up a nucleotide.

What are the repeating subunits called that make up DNA?

Macromolecules are very large molecules often consisting of repeating subunits. RNA and DNA are made up of subunits called nucleotides.

What are the subunits monomer of DNA?

The monomers of DNA are called nucleotides. Nucleotides have three components: a base a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A) cytosine (C) guanine (G) and thymine (T).

What makes up the DNA backbone quizlet?

The backbone is comprised of alternating pairs of Sugars (Deoxyribose) and Phosphate groups. The rungs of DNA are comprised of pairs of Nitrogenous Bases. These bonds hold the nitrogen bases together.

What is the sequence of subunits in the DNA backbone?

(Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A) thymine (T) cytosine (C) and guanine (G). (A grouping like this of a phosphate a sugar and a base makes up a subunit of DNA called a nucleotide.)

What are the subunits of RNA?

Five small subunits Sc5 Sc6 Sc8 Sc10 and Sc10 (22 44 49 52) are present in all three nuclear RNA polymerases (11 12 37 46). These 10 specific or common subunits are essential components of the transcription apparatus as strains carrying the corresponding null alleles are nonviable.

What are the subunits called that make up carbohydrates?

Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called monosaccharides. Monosaccharides have carbon hydrogen and oxygen in a 1:2:1 ratio.

What subunits make up proteins?

Proteins are made of subunits called amino acids and are used to build cells and do much of the work inside organisms. They also act as enzymes helping to control metabolic reactions in organisms. Amino acids contain two functional groups the carboxyl group (-COOH) and the amino group (-NH2).

What subunits make up each kind of large molecule?

Most macromolecules are made from single subunits or building blocks called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers.

What is DNA made up of?

The information in DNA is stored as a code made up of four chemical bases: adenine (A) guanine (G) cytosine (C) and thymine (T). Human DNA consists of about 3 billion bases and more than 99 percent of those bases are the same in all people.

The part of the cell which occurs between plasma membrane and nuclear membrane is called cytoplasm. The inner granular mass of cytoplasm is called endoplasm. … Cytoplasm consist of an aqueous ground substance called Cytosol which contain variety of cell organelles. insoluble waste storage products.

What is chromosome by Byjus?

Chromosome. Chromosomes are the genetic material present in all cells. They are present in the nucleus of a eukaryotic cell. They are a thread-like structure. Each chromosome of a eukaryotic cell contains DNA and associated proteins known as histone proteins.

What are 3 subunits of lipids?

There are three important families of lipids: fats phospholipids and steroids. Fats are large molecules made of two types of molecules glycerol and some type of fatty acid. The fatty acid has a long chain of carbon and hydrogen usually referred to as the hydrocarbon tail with a carboxyl group head.

What are the subunits that make up each of the macromolecules?

Most macromolecules are made from single subunits or building blocks called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers.

What are the subunits that make up fats?

Fats are made of a glycerol (alcohol) and three fatty acid chains. This subunit is called a triglyceride. The fatty acid chains may be saturated (only single bonds between carbons) or unsaturated (contain at least one double bond).

How do the 4 bases of DNA pair up?

​Base Pair. … Attached to each sugar is one of four bases–adenine (A) cytosine (C) guanine (G) or thymine (T). The two strands are held together by hydrogen bonds between the bases with adenine forming a base pair with thymine and cytosine forming a base pair with guanine.

Which nucleotide parts make up the rungs of the DNA ladder?

The rungs of the ladder are pairs of 4 types of nitrogen bases. Two of the bases are purines- adenine and guanine. The pyrimidines are thymine and cytosine. The bases are known by their coded letters A G T C.

What are the rungs of a ladder?

A rung is one of the horizontal steps of a ladder. You should never stand on the very top rung of a ladder — it can be dangerous!

What are the subunits of a single strand of DNA?

The subunits of a strand of DNA are called nucleotides.

Which of the following is the structural subunit of DNA?


Nucleotides make up the structural subunit of DNA which in turn makes three subunits – a phosphate group a 5-carbon sugar (deoxyribose) and a nitrogen base.

What are the subunits of DNA & their function?

Nucleotides are the subunits of DNA they form the genetic code.

How many monomers make up DNA?


DNA is a polymer made from four different monomers called nucleotides . These join together in different combinations to make long strands. In a DNA molecule two strands wrap around each other to form a double helix structure.

What makes up the backbone of DNA?

​Phosphate Backbone

DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A) cytosine (C) guanine (G) or thymine (T).

How many nucleotides make up a DNA?

four nucleotides
DNA molecules are composed of four nucleotides and these nucleotides are linked together much like the words in a sentence. Together all of the DNA “sentences” within a cell contain the instructions for building the proteins and other molecules that the cell needs to carry out its daily work.

What three components make up DNA structure?

What is DNA made of? DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group a sugar group and one of four types of nitrogen bases. To form a strand of DNA nucleotides are linked into chains with the phosphate and sugar groups alternating.
