In contrast, a prokaryotic cell (right) does not have membrane-bound DNA and also lacks other membrane-bound organelles as well. © 2010 Nature Education All rights reserved. How Did Cells Originate? Researchers hypothesize that all organisms on Earth today originated from a single cell that ...
which tells the cell how to make proteins, and ribosomes, which make the proteins, the manner in which the cell does this depends on whether the cell is prokaryotic or eukaryotic. The prokaryotic ribosome
What does cell division enable cells to do? What is a living organism that doesn't contain cells in its structure called? What type of organisms are epithelial cells found in? 1. What are cells with an enclosed nucleus called? What are the main elements of the nucleus? 2. Do all...
How does protein synthesis enable DNA to control the cell? Explain how mRNA contains information from a gene. What are the bases that make up DNA? Explain how DNA is used to generate proteins in prokaryotic and eukaryotic cells. What is the process of DNA sequencing?
Genes are contained in chromosomes. These in the cell nucleus. A single chromosome contains hundreds to thousands of genes. Every normal human cell comprises 23 pairs of chromosomes that mean a total of 46 chromosomes. A trait is any gene-determined characteristic. It is ofte...
Most prokaryotic organisms consist of only a single cell, whereas the bodies of eukaryotes such as yourself contain trillions. Eukaryotic cells contain specialized structures called organelles, which include a membrane similar to the one surrounding the whole cell. These organelles are the cell's groun...
•Cell membrane:A phospholipid bilayer around the outside of the cell. •Cytoplasm:The gel-like substance that fills the space inside cells and serves as a place for reactions and other processes to occur. Prokaryotic cellsmake only a limited number of proteins and have no compelling need ...
