DNA and Protein Synthesis Test

Front

What are the components of a DNA nucleotide?

Back

A DNA nucleotide consists of a phosphate group, a deoxyribose sugar, and a nitrogenous base (adenine, thymine, cytosine, or guanine).

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 the role of RNA in protein synthesis?

Back

RNA serves as a messenger that carries genetic information from DNA to the ribosomes, where proteins are synthesized.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which occurs in the nucleus.

Front

What is translation?

Back

Translation is the process where ribosomes synthesize proteins using the information carried by mRNA.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.

Front

Where does protein synthesis occur in the cell?

Back

Protein synthesis occurs in the ribosomes, which can be found in the cytoplasm or on the rough endoplasmic reticulum.

Front

What are the differences between DNA and RNA?

Back

DNA is double-stranded, contains deoxyribose sugar, and uses thymine; RNA is single-stranded, contains ribose sugar, and uses uracil instead of thymine.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes facilitate the translation of mRNA into a polypeptide chain, assembling amino acids in the correct order.

Front

What are the four nitrogenous bases in DNA?

Back

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