Chapter 10.3, Problem 3MI

Summary Introduction

To define:

The word “protein” using a book or a dictionary

Introduction:

Chromosomes are the structures that contain the genetic material that are passed from generation to generation of cells. A chromosome consist of two identical sister chromatids. Sister chromatids are the structures that contain identical copies of DNA. Chromosomes contain multiple genes that code for proteins.

Answer to Problem 3MI

Protein refers to the large complex polymers essential to all life that provides structure for tissues and organs and helps carry out cell metabolism.

Explanation of Solution

The DNA codes for RNA which guides the synthesis of proteins. Through transcription, the DNA code is transferred to mRNA and through translation the nucleotide sequence on mRNA code is converted to amino acid sequence. Different sequences of amino acids code for different proteins.

Proteins are essential to all living organisms for building tissues and organs. They are needed to carry out various metabolic processes.
