7.1 DNA Structure and Function

DNA stands for

• Deoygenated Neogenetic Ability

• Deoxyribonucleic Acid

• Determined Natural Algorithm

• Denatured Nucleic Acids

The basic building block for a nucleic acid is a

• protein

• amino acid

• nucleotide

• ribose sugar

Answer explanation

The basic building block for a nucleic acid is a nucleotide, which consists of a nitrogenous base, a phosphate group, and a pentose sugar.

DNA is made up of four nucleotide. Adeline, Thymine, Guanine and

• Cytosine

• Uracil

• Ribosine

• Helicase

Answer explanation

DNA is made up of four nucleotides: Adeline, Thymine, Guanine, and Cytosine. Therefore, the correct choice is Cytosine.

DNA is ____________ meaning it can be passed down from parent to offspring

• nuclear regulated

• heritable

• easily modified

• self repairing

Answer explanation
