Question

drag the terms on the left to the appropriate blanks on the right to complete the sentences. 1. nucleic acids are polymers of blank. 2. the monomers of nucleic acids consist of a phosphate group, a five - carbon sugar, and a blank. 3. blank provides directions for its own replication. it also directs cell activities by providing instructions for building proteins. 4. a gene provides the directions to build a molecule of blank; the genetic instructions it carries are then translated into the amino acid sequence of a protein. 5. a polynucleotide has a repeating blank backbone. 6. the structure of dna is a blank, held together by the complementary base - pairing of cytosine with guanine, and adenine with thymine. 7. rna usually consists of a single blank strand. double helix sugar - phosphate nucleotides rna (ribonucleic acid) nitrogenous base dna (deoxyribonucleic acid) polynucleotide

Explanation:

1. Nucleic acids are polymers of nucleotides. Nucleotides are the building - blocks.
2. Nucleotide monomers have a phosphate, a five - carbon sugar, and a nitrogenous base.
3. DNA provides self - replication directions and protein - building instructions.
4. A gene gives directions to build RNA which is translated to protein.
5. Polynucleotides have a sugar - phosphate backbone.
6. DNA has a double helix structure with base - pairing.
7. RNA usually has a single polynucleotide strand.

Answer:

1. nucleotides
2. nitrogenous base
3. DNA (deoxyribonucleic acid)
4. RNA (ribonucleic acid)
5. sugar - phosphate
6. double helix
7. polynucleotide
