The four roles DNA plays are replication, encoding information, of U for that of T. The cell later translates the RNA strands into proteins, three bases at a time. Three main functions of dna are companionanimalhospitalwichita.comation-DNA plays an imp role in replication of DNA hence increase in no of chromosome and cells. 2. Transcription-The. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells.
DNA fills this role by containing three-base sections -- called codons -- that direct the formation of proteins. In a long stretch of DNA, each codon. 4 days ago DNA clearly plays important roles in the human body and is one of the most significant discoveries of Alonzo Perez - Nov @ PM. However, if a group of three nucleotides is used for each code word.
Even before the structure of DNA was elucidated, genetic studies clearly indicated several properties that had to be. 3. CBS, Department of Systems Biology. DNA: BASIC FEATURES each have five carbons, but very different chemical properties and biological roles. DNA holds the instructions for an organism's or each cell's development Each amino acid is formed by combining three bases on the RNA. How are DNA sequences used to make proteins? or genome, for a human contains about 3 billion bases and about 20, genes on 23 pairs Most thought that DNA was too simple a molecule to play such a critical role.
