What is the secondary structure of proteins?

Back

The secondary structure of proteins refers to the α-helix and β-pleated sheet folding that occurs due to hydrogen bonding between the backbone of the polypeptide chain.

Front

Does DNA contain the template to make RNA?

Back

True

Front

What gives a protein its unique shape?

Back

A protein's unique shape is determined by the unique sequence of amino acids in its polypeptide chain, the unique folding due to this sequence, and hydrogen bonding & unique interactions between the 'R' groups.

Front

What is cleavage in cellular biology?

Back

Cleavage is the pinching of the plasma membrane during cell division.

Front

What base does RNA have instead of thymine?

Back

Uracil.

Front

What are the building blocks of proteins?

Back

Amino acids.

Front

What is the primary structure of proteins?

Back

The primary structure of proteins is the linear sequence of amino acids in a polypeptide chain.

Front

What type of bond stabilizes the secondary structure of proteins?

Back

Hydrogen bonds.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular machinery that assembles amino acids into proteins based on the sequence of mRNA.

Front

What is transcription in the context of genetics?

Back

Transcription is the process of copying a segment of DNA into RNA.
