What are the subunits of DNA and what is their function?

Nucleotides are the subunits of DNA. The four nucleotides are adenine, cytosine, guanine and thymine. Each of the four bases has three components, a phosphate group, a deoxyribose sugar and a nitrogen-containing base. These four nucleotides, referred to as the A, C, G and T are the building blocks of DNA.

What are the DNA subunits?

Each chain is made up of repeating subunits called nucleotides that are held together by chemical bonds. There are four different types of nucleotides in DNA, and they differ from one another by the type of base that is present: adenine (A), thymine (T), guanine (G), and cytosine (C).

What are the subunits of DNA and RNA quizlet?

Nucleotides are the subunits of DNA and RNA.

What is the subunit for an RNA molecule?

RNA and DNA are made up of subunits called nucleotides. The two nucleic acids team up to create proteins. The process of creating proteins using the genetic information in nucleic acids is so important to life that biologists call it “the central dogma” of molecular biology.

What is the function of DNA bases?

Each nucleic acid strand contains certain nucleotides that appear in a certain order within the strand, called its base sequence. The base sequence of deoxyribonucleic acid (DNA) is responsible for carrying and retaining the hereditary information in a cell.

What is the function of the nucleotide bases in DNA?

They also have functions related to cell signaling, metabolism, and enzyme reactions. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine.

What are the bases of DNA and RNA quizlet?

The nitrogenous bases in DNA are adenine (A), guanine (G), thymine (T), and cytosine (C). The nitrogenous bases in RNA are the same, with one exception: adenine (A), guanine (G), uracil (U), and cytosine (C).

What are the 3 subunits that make up the DNA molecule?

DNA is made of smaller subunits called nucleotides. Each nucleotide consists of three components: a five-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base.

Which event occurs during the elongation stage?

During the elongation stage, the ribosome continues to translate each codon in turn. Each corresponding amino acid is added to the growing chain and linked via a bond called a peptide bond. Elongation continues until all of the codons are read.

What is the basic function of RNA?

The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.

What significant role does DNA play in the formation and development of an organism?

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
