Admin What molecule contains the instructions cells need to carry out the functions of life?
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
What do cells store in lipids to use later?
Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of lipids called fats. Lipids also provide insulation from the environment for plants and animals.
What is the role of nucleic acids in the nucleus and cytoplasm?
Structure of Nucleic Acids. Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. It is found in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria.
Which organelle holds the instructions for making proteins?
The nucleus is the largest organelle in a eukaryotic cell and is considered to be the cell’s control center. It contains most of the cell’s DNA, which makes up chromosomes and is encoded with the genetic instructions for making proteins.
Which organelle provides passageways for molecules to travel throughout the cell?
Endoplasmic Reticulum (ER) – A maze of passageways that carries proteins and other substances from one part of the cell to another. There are two (2) types of ER. Rough ER, which contains Ribosomes. Rough ER is located around and near the Nucleus.
Which of the following is the instructions for making a protein?
Messenger RNA (mRNA) carries the instructions for making proteins. Like DNA, proteins are polymers: long chains assembled from prefab molecular units, which, in the case of proteins, are amino acids. A large molecular machine* called the ribosome translates the mRNA code and assembles the proteins.
