What are DNA pieces called?
on the outsides there is phosphate and a sugar called dyoxiribose...spelling... and the insides are like rungs on a ladder, theres adenine which pairs up with thymine... and guanine which pairs up with cytosine
What two strands of DNA join together to form?
Two strands of DNA join together to form a double helix. These strands are composed of nucleotides, and they pair through complementary base pairing: adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). The sugar-phosphate backbone of each strand runs in opposite directions, which is referred to as antiparallel orientation. This structure is fundamental to DNA's stability and its function in storing genetic information.
What rule is used to join the free nucleotides to the exposed bases of the DNA?
The rule used to join free nucleotides to the exposed bases of DNA is base pairing. Adenine pairs with thymine, and guanine pairs with cytosine through hydrogen bonding. This complementary base pairing ensures the accurate replication of DNA during cell division.
How many diagonals does an arrow head have and where are they?

Which nucleotides hook together?
adenine and guantine hook together while thymine and cytosine hook together.
How does 4 nucleotides polymerize to form nuclic acid?
Nucleotides polymerize through a condensation reaction between the phosphate group of one nucleotide and the sugar group of another nucleotide. This forms a phosphodiester bond, linking the nucleotides together to form a nucleic acid chain. DNA and RNA are examples of nucleic acids formed by polymerization of nucleotides.
How does DNA reproduce itself?
DNA reproduces through a set process that begins when it unzips and uncoils. Next, two polynucleotide chains are produced and adenine lines up with thymine. Cytosine lines up with guanine, and then hydrogen bonds form between the pairs. Enzymes join the nucleotides together, and two new DNA molecules are formed.
How do the radioactively labeled dideoxynucleotides terminate DNA synthesis?
Dideoxynucleotides have no OH group on the sugar of the nucleotides, only H's. That means phosphate groups can't react with the sugar to form a phosphodiester bond to join two nucleotides together, so DNA syntheses is terminated
How does nucleotide dehydration synthesis contribute to the formation of DNA and RNA molecules?
Nucleotide dehydration synthesis is a process where nucleotides join together to form DNA and RNA molecules. During this process, a water molecule is removed, allowing the nucleotides to bond together. This contributes to the formation of DNA and RNA by creating the long chains of nucleotides that make up these molecules.
What is the rule to join the free nucleotides to the exposed bases of the DNA?
watson-base pairing
What two atoms of oxygen join to form an oxygen family?
Two atoms of oxygen join to form the oxygen family by sharing two pairs of electrons in a covalent bond, resulting in the formation of O2 molecule which is stable and represents the oxygen family in the periodic table.
What is created when nucleotides join together into a polynucleotide?
When nucleotides join together into a polynucleotide, they form a long chain known as a nucleic acid, such as DNA or RNA. This process involves the formation of phosphodiester bonds between the sugar of one nucleotide and the phosphate group of another, creating a backbone that holds the sequence of nitrogenous bases. The specific arrangement of these bases encodes genetic information essential for biological functions.
