Front

What is the monomer of DNA?

Back

Nucleotide

Front

How do photosynthesis and cellular respiration demonstrate interdependence?

Back

The products of one are the reactants of the other.

Front

How does DNA code for physical traits if it never leaves the nucleus in eukaryotic organisms?

Back

The DNA in the nucleus can be transcribed into mRNA, which then leaves the nucleus and is translated into proteins that make up physical traits.

Front

What is the primary function of insulation in biological systems?

Back

Insulation helps to maintain body temperature and protect against environmental changes.

Front

What type of mutation is represented by the change from TAC ATG GGG CAC ATT to TAC ATA GGG CAC ATT?

Back

Substitution.

Front

What are the three main components of a nucleotide?

Back

A phosphate group, a sugar (deoxyribose in DNA), and a nitrogenous base.

Front

What are the four nitrogenous bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm for protein synthesis.

Front

What is the process of transcription?

Back

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of mRNA.

Front

What is the process of translation?

Back

Translation is the process by which the sequence of nucleotides in mRNA is used to assemble a chain of amino acids to form a protein.
