Flashcards- Chap 17 Part 1- Transcription

Front

DNA is called the "code of life." What does this mean?

Back

The information ("code") to make proteins.

Front

Gene

Back

A specific sequence of DNA bases that can code for a specific protein.

Front

What would be the mRNA sequence that complements the DNA sequence shown?

Back

G-U-C-A

Front

Importance of proteins

Back

Proteins carry out nearly every function of a living thing, including DNA replication, forming structural proteins, transporting molecules, fighting infections, and acting as enzymes.

Front

Examples of structural proteins

Back

Structural proteins include those found in skin (such as collagen) and muscles (such as actin and myosin).

Front

Function of transport proteins

Back

Transport proteins, such as hemoglobin and membrane channels, help move substances across cell membranes.

Front

Proteins help fight infection

Back

Proteins function as antibodies to help fight infections.

Front

Role of enzymes in digestion

Back

Enzymes, which are proteins, help digest food through hydrolysis reactions.

Front

How does DNA's code relate to a protein?

Back

The DNA nucleotide sequence determines the order of amino acids in a protein chain.

Front

Proteins are long chains of what?

Back

Proteins are long chains of amino acids.
