Genetics (No Gen Tech)

What are the components of a DNA nucleotide?

• Phosphate, Deoxyribose, Nitrogen Bases (ATCG)

• Phosphate, Ribose, Nitrogen Bases (AUCG)

• Amino acids, Ribose, Nitrogen Bases (ATCG)

• Phosphate, Deoxyribose, Amino acids

During DNA replication, what is the role of Helicase?

• It bonds amino acids together to build proteins.

• It unzips DNA by breaking Hydrogen Bonds.

• It transfers the coded message to the ribosome.

• It synthesizes mRNA from the DNA template.

What is the result of DNA replication?

• One template strand and one identical strand are created.

• Two template strands are created.

• Two identical strands are created from one template strand.

• Two nitrogen bases attach to each template strand creating 2 identical strands.

What is the correct sequence of genetic information flow in protein synthesis?

• DNA → RNA → Protein

• RNA → DNA → Protein

• Protein → RNA → DNA

• DNA → Protein → RNA

What is a key difference between DNA and RNA?

• DNA contains phosphate while RNA does not.

• RNA contains uracil instead of thymine.

• DNA is single-stranded while RNA is double-stranded.

• RNA is found only in the nucleus while DNA is found throughout the cell.

What is the relationship between a trait, an allele, and a gene?

• Trait → Gene → Allele

• Allele → Trait → Gene

• Gene → Allele → Trait

• Trait → Allele → Gene

What is biodiversity?

• The study of genes and their functions.

• The variety of life in the world or in a particular habitat or ecosystem.

• The process of selective breeding in plants and animals.

• The genetic modification of organisms.

What is the term used to describe the shape of DNA?

• Single Helix

• Double Helix

• Triple Helix

• Quadruple Helix

Which of the following is not a nitrogenous base found in DNA?
