23 pairs
A scientist treats a cell with a chemical that destroys the ribosomes. As a result, which cell process will be stopped?
Protein Synthesis
What is this definition?
Two characteristics that are similar because they originated from a common ancestor
Homologous
Translation is crucial to the process of making proteins. Describe what takes place during translation.
Information from mRNA is a converted into a sequence of amino acids in a protein

What is this definition?
The study of past and present geographical distribution of species.
Biogeography
In order for DNA instructions to move from the nucleus to the ribosomes in the cytoplasm of a cell, an RNA copy of a DNA strand must be made. This process, which takes place in the cell nucleus, is called-
