What is a Start Codon?

Back

A Start Codon is a specific sequence of three nucleotide bases (AUG) that signals the beginning of protein synthesis.

Front

What is a Monomer?

Back

A Monomer is the smallest unit of a macromolecule, which can join together to form polymers.

Front

What occurs during Mitosis?

Back

Mitosis is the part of the cell cycle where the cell divides into two daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is a Histone?

Back

A Histone is a disc-shaped protein that DNA wraps around to form nucleosomes, helping to package DNA into a compact structure.

Front

What are Nucleotides?

Back

Nucleotides are the monomers of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the function of a Stop Codon?

Back

A Stop Codon is a sequence of three nucleotide bases that signals the termination of protein synthesis.

Front

What is a Polymer?

Back

A Polymer is a large molecule made up of repeating structural units (monomers) connected by covalent bonds.

Front

What is the role of Anticodons?

Back

Anticodons are sequences of three nucleotides in tRNA that pair with complementary codons in mRNA during protein synthesis.

Front

What is the difference between Interphase and Mitosis?

Back

Interphase is the phase of the cell cycle where the cell prepares for division, while Mitosis is the actual division of the cell.

Front

What is Chromatin?

Back

Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.
