What Are The Features Of The DNA Double Helix? It contains two polynucleotide strands wound around each other. The backbone of each consists of alternating deoxyribose and phosphate groups. The phosphate group bonded to the 5′ carbon atom of one deoxyribose is covalently bonded to the 3′ carbon of the next. What are the other
What Is The Correct Structure Of DNA? DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). What are the 3 structures of DNA? The Building Blocks of
What Is The Structure Of DNA Left Side Right Side? The side of the chain on the left begins with a free phosphate group at the top and ends with a sugar molecule at the bottom. In contrast, the complementary chain on the right begins at the top with a sugar molecule and ends at
What Is The Only Part Of A Nucleotide That Changes? Base substitution For example, during replication, a thymine nucleotide might be inserted in place of a guanine nucleotide. With base substitution mutations, only a single nucleotide within a gene sequence is changed, so only one codon is affected (Figure 1). What is the part of
Do Dna Cells Only Rep Icate In 15 Media? >The mechanism by which a double-stranded DNA molecule is copied to produce two identical DNA molecules is called DNA replication. > Replication is an important process because, whenever a cell divides, the two new daughter cells must contain the same genetic information which is in the
