Unit 7 Flashcards

Front

Double helix

Back

Front

Semi-conservative model

Back

The method of DNA replication where each of the two parental DNA strands act as a template for new strands.

Front

Template

Back

A strand of DNA or RNA that serves as a guide for the synthesis of a complementary strand.

Front

Purine

Back

A type of nitrogenous base found in DNA and RNA, including adenine and guanine.

Front

Complementary strand

Back

A strand of DNA or RNA that pairs with another strand according to base pairing rules.

Front

Covalent bond

Back

The chemical bond that connects the amino acids to each other

Front

Nucleotide

Back

The basic building block of nucleic acids, consisting of a sugar, a phosphate, and a nitrogenous base.

Front

Pyrimidine

Back

A type of nitrogenous base found in DNA and RNA, including cytosine, thymine, and uracil.

Front

Chargaff’s base pairing rule

Back

The rule stating that in DNA, the amount of adenine equals thymine and the amount of guanine equals cytosine.

Front

Guanine

Back

A purine base found in DNA and RNA, pairs with cytosine.
