The proteins that a cell makes are determined by the DNA sequence in its genes. Gene expression is regulated by factors such as transcription factors, cell signaling pathways, and environmental cues. These factors influence which genes are transcribed and ultimately which proteins are produced by the cell.
The cell membrane, which is a semi-permeable structure made up of lipids and proteins, regulates what enters and exits the cell. It controls the movement of substances like nutrients, ions, and waste products in and out of the cell to maintain internal balance and proper functioning.
The presence of a signal sequence within the protein determines whether it is exported from the cell or used inside. Proteins with signal sequences are recognized by the cellular machinery for export. Proteins without signal sequences generally remain in the cell to perform their functions.
The information that determines a cell's purpose and function is stored in its DNA. DNA contains the instructions for making proteins, which play key roles in carrying out various cellular functions and determining the cell's characteristics. These instructions are read and executed by the cell through processes like transcription and translation.
The DNA, located in the cell's nucleus, determines the characteristics of a living thing through the expression of genes. Genes provide the instructions for producing proteins that drive various cellular functions, ultimately influencing the organism's traits and behaviors.
The nucleus of the cell contains the chromosomes. Chromosomes are made up of DNA and proteins and carry genetic information that determines an organism's characteristics.
the ribosome makes proteins
The DNA molecule is the cell's instructions. It is the information contained in this molecule that determines what proteins the cell makes, and we are thinking that a certain part of the molecule called telomeres may even tell the cell how long to live.
Proteins are synthesized in the cell by a process called protein synthesis. This process involves transcription of the DNA sequence into mRNA and translation of the mRNA into proteins by ribosomes. The sequence of nucleotides in the mRNA determines the sequence of amino acids in the protein, allowing for the correct protein structure and function.
Proteins are made of amino acids, not cells.
Proteins are made in the Rough Endoplasmic Reticulum.
The cell organelle that makes proteins is called the ribosomes .

The cell membrane, which is a semi-permeable structure made up of lipids and proteins, regulates what enters and exits the cell. It controls the movement of substances like nutrients, ions, and waste products in and out of the cell to maintain internal balance and proper functioning.
It makes the ribosomes which make proteins.

DNA determines the genetic information of a cell, including the characteristics and functions of the organism. It contains instructions for making proteins, which are essential for various cellular processes such as growth, development, and reproduction. Additionally, DNA plays a crucial role in regulating gene expression and determining the overall structure and function of a cell.
