What makes nucleic acid structure unique?

Nucleic acid types differ in the structure of the sugar in their nucleotides–DNA contains 2′-deoxyribose while RNA contains ribose (where the only difference is the presence of a hydroxyl group).

What is it about DNA that allows every organism to be unique?

Although each organism’s DNA is unique, all DNA is composed of the same nitrogen-based molecules. So how does DNA differ from organism to organism? It is simply the order in which these smaller molecules are arranged that differs among individuals.

What makes each amino acid chemically unique?

In addition to the amino and carboxyl groups, amino acids have a side chain or R group attached to the α-carbon. Each amino acid has unique characteristics arising from the size, shape, solubility, and ionization properties of its R group.

How many unique DNA combinations are there?

In a tetranucleotide block where the nucleotides can appear more than once and the order is random, there can be 256 possible combinations. 256 is a large number of possible DNA letters.

What makes up nucleotides in DNA?

A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).

What makes one DNA molecule different from another?

The sequence of nitrogenous bases in a DNA molecule makes one DNA molecule different from another.

Which part of an amino acid makes it unique quizlet?

The side chain of an amino acid is what gives the amino acid its unique chemical properties. All 20 naturally occurring amino acids are different from one another in the atoms that compose the side chain, which gives individual amino acids their unique chemical properties. You just studied 16 terms!

What are the 4 categories of amino acids?

Four Categories of Amino Acids

• Non-Polar and Neutral. A chemical is non-polar if it is uncharged.
• Polar and Neutral. In contrast, polar amino acids have side chains with either a net positive or a net negative charge.
• Polar and Acidic.
• Polar and Basic.

What is DNA nucleic acid?

​Nucleic Acid Nucleic acid is an important class of macromolecules found in all cells and viruses. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins. A related type of nucleic acid, called ribonucleic acid (RNA), comes in different molecular forms that participate in protein synthesis.
