Some isotopes, however, decay slowly, and several of these are used as geologic clocks. Dating rocks by these radioactive timekeepers is simple in theory, but the laboratory procedures are complex. <span>All methods rely on the fact that certain elements (particularly uranium and potassium) contain a number of different isotopes whose half-life is exactly known and therefore the relative concentrations of these isotopes within a rock or mineral can measure the age.</span>
Answer:
The correct answer will be - Primary structure
Explanation:
Proteins are one of the biomolecules formed by the process of translation.
Depending on the function they attain many structures like primary, secondary, tertiary and Quaternary structure.
The primary structure is the simplest structure formed by binding the amino acids via peptide bonds in linear order. This simplest structure is formed by the process of translation in which tRNA brings specific amino acids to the nascent peptide.
Thus, Primary structure is the correct answer.
Cellular compartment. Cellular compartments in cell biology comprise all of the closed parts within the cytosol of a eukaryotic cell, usually surrounded by a single or double lipid layer membrane. These compartments are often, but not always, defined as membrane enclosed regions.
<span>M (mitosis) phase is itself composed of two tightly coupled processes: mitosis, in which the cell's chromosomes are divided between the two daughter cells, and cytokinesis, in which the cell's cytoplasm divides in half forming distinct cells.</span>
