Amino acids are linked by _______ bonds and held together by _______ bonds.

hydrogen, peptide

peptide, hydrogen

ionic, covalent

covalent, ionic

Answer explanation

Amino acids are linked by peptide bonds, which are a type of covalent bond. They are held together in a protein structure by hydrogen bonds, which stabilize the overall shape of the protein.

Protein synthesis is the process of amino acids determining specific DNA sequences in order to create varying proteins.

True

False

Sometimes true

Always true

Answer explanation

The statement is false because protein synthesis involves ribosomes translating mRNA sequences into amino acids, not the other way around. Amino acids are determined by mRNA, which is transcribed from DNA.

During transcription, RNA _______ helps to create a copy of DNA, called _______.

polymerase, mRNA

mRNA, polymerase

DNA, transcription

transcription, DNA

Answer explanation

During transcription, RNA polymerase synthesizes a complementary RNA strand from the DNA template, resulting in the formation of mRNA. Thus, the correct answer is 'polymerase, mRNA'.

Primary structure occurs in a _______.

Three-dimensional pattern

Linear pattern

Globular pattern

Fibrous pattern

Answer explanation

Primary structure refers to the linear sequence of amino acids in a protein. This linear pattern is crucial as it determines the protein's overall structure and function.
