DNA AND PROTEIN SYNTHESIS and Dichotomous Keys Test

Front

What is DNA?

Back

DNA stands for Deoxyribonucleic Acid, which is the molecule that carries the genetic instructions for life.

Front

What are the four nitrogen bases in DNA?

Back

The four nitrogen bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the sugar found in DNA?

Back

The sugar found in DNA is deoxyribose.

Front

What is the sugar found in RNA?

Back

The sugar found in RNA is ribose.

Front

What forms the backbone of the DNA ladder?

Back

The backbone of the DNA ladder is formed by deoxyribose sugar and phosphate.

Front

What is the base pairing rule in DNA?

Back

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is transcription in protein synthesis?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using the mRNA sequence.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is a dichotomous key?

Back

A dichotomous key is a tool that allows the identification of organisms based on a series of choices that lead the user to the correct name.
