Genetics: DNA Structure

What is the full form of DNA?

• Deoxyribonucleic Ammonia

• Dihydrogen Nitrogen Atom

• Deoxyribonucleic Acid

• Deoxyribonucleic Acid

What are the building blocks of DNA?

• Nucleotides

• Proteins

• Lipids

• Carbohydrates

What are the four nitrogenous bases found in DNA?

• Adenosine

• Thymidine

• Uracil

• Guanosine

• Adenine, Thymine, Guanine, Cytosine

Describe the double helix structure of DNA.

• DNA double helix consists of three strands instead of two.

• The double helix structure of DNA consists of two strands twisted around each other, with nucleotides forming the backbone and specific base pairs (adenine-thymine, guanine-cytosine) connecting the strands.

• The double helix structure of DNA is a single-stranded linear molecule.

• In the double helix structure of DNA, the base pairs are randomly connected.

What is the function of DNA in cells?

• DNA is responsible for cell movement

• DNA regulates cell division

• DNA stores genetic information and controls the production of proteins in cells.

• DNA produces energy for cells

Explain the process of DNA replication.

• The process of DNA replication involves initiation, elongation, and termination to produce two identical DNA molecules.

• DNA replication involves photosynthesis

• DNA replication only produces one DNA molecule

• DNA replication occurs in the cytoplasm

How does DNA store genetic information?

• By forming hydrogen bonds

• Through a sequence of nucleotides

• Through a sequence of amino acids

• Via a network of proteins

What is the significance of DNA structure in genetics?

• DNA structure contains genetic information that determines traits and characteristics, serving as the genetic code for inheritance and genetic variation.

• DNA structure only affects physical appearance

• DNA structure has no impact on inheritance

• DNA structure is irrelevant in genetics
