Final Review: DNA, Protein Synthesis, Mutation, Biochem

Front

What are the three components of a DNA nucleotide?

Back

A DNA nucleotide is composed of a deoxyribose sugar, a phosphate group, and a nitrogenous base.

Front

What two components make up the backbone of a DNA nucleotide?

Back

The backbone of a DNA nucleotide is made up of deoxyribose sugar and phosphate group.

Front

What do amino acids form when they link together?

Back

Amino acids form a chain to make proteins.

Front

What is the central dogma of molecular biology?

Back

The central dogma is DNA --> mRNA --> protein.

Front

What does semi-conservative replication mean in DNA?

Back

Semi-conservative replication means that each new DNA molecule consists of one original strand and one new strand.

Front

In double-stranded DNA, which base pairs with Adenine?

Back

Thymine pairs with Adenine in double-stranded DNA.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

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

What are the four nitrogenous bases in DNA?

Back

The four nitrogenous bases in DNA are Adenine, Thymine, Cytosine, and Guanine.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites where amino acids are assembled into proteins.
