Unit 3 Vocab

What is a double helix?

• An error that occurs during DNA replication

• Material in the cell that contains genetic information

• The shape of DNA, resembling a twisted ladder

• The process of duplication

What is DNA?

• Material in the cell that contains genetic information.

• A protein that facilitates a specific chemical reaction in the body.

• A sub unit of a nucleic acid molecule that consists of a sugar and a nitrogenous base.

• A sub unit of a nucleic acid molecule that consists of a sugar and a nitrogenous base.

What does enzyme do?

• It's a double-stranded DNA molecule that divides into two single

  strands.

• It's a component of DNA that forms the “rungs” in the DNA structure.

• It's an error that occurs during DNA replication.

• It's a protein that sets of a specific chemical reaction in the body.

What is a Mutation?

• DNA helical and DNA polymer are enzymes that assist in DNA replication.

• An error that occurs during DNA replication.

• There are four nitrogenous bases in DNA: adenine, thymine, cytosine, and guanine.

• a sub-unit of a nucleic acid molecule that consists of a sugar and a nitrogenous base.

What is a Nucleoside?

• A sub-unit of a nucleic acid molecule that consists of a sugar and a nitrogenous base.

• Each “rung” of DNA is composed of a bonded pair of nitrogenous bases. Adenine bonds to thymine while cytosine bonds to guanine.

• The end result is two identical strands of DNA.

• The process of duplication.

What is replication?

(pick two of them)

• During DNA replication, a double-stranded DNA molecule divides into two single strands. New nucleotide bond to each single strand. The end result is two identical strands of DNA.

• The process of duplication.

• Mutations can be harmful, helpful, or neutral. Most mutations are neutral.

• The shape of DNA, resembling a twisted ladder.

Nucleotide

• A sub-unit of a nucleic acid molecule that consists of a sugar and a nitrogenous base.

• Each “rung” of DNA is composed of a bonded pair of nitrogenous bases. Adenine bonds to thymine while cytosine bonds to guanine.

• A sub-unit of a nucleic acid molecule that consists of a sugar, a phosphate,

  and a nitrogenous base.

• DNA helical and DNA polymer are enzymes that assist in DNA replication.

Nitrogenous base

which one is incorrect?

• A component of DNA that forms the “rungs” in the DNA structure.

• Each “rung” of DNA is composed of a bonded pair of nitrogenous bases. Adenine bonds to thymine while cytosine bonds to guanine.

• During DNA replication, a double-stranded DNA molecule divides into two single strands. New nucleotides bond to each single strand. The end result is two identical strands of DNA.

• There are four nitrogenous bases in DNA: adenine, thymine, cytosine, and guanine.
