Unit 3 Review - DNA and Genetics

Front

What is the process by which the genetic code of DNA is copied into a strand of RNA?

Back

Transcription

Front

How would you describe the structure of a DNA molecule?

Back

Double helix

Front

What is one key difference between RNA and DNA?

Back

RNA contains uracil and ribose.

Front

What determines the information of a DNA molecule?

Back

The order (sequence) of the nitrogen bases.

Front

What does a homozygous dominant genotype look like?

Back

RR

Front

What are the building blocks of DNA?

Back

Nucleotides, which consist of a sugar, a phosphate group, and a nitrogen base.

Front

What are the four nitrogen bases found in DNA?

Back

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

Front

What is the complementary base pairing in DNA?

Back

Adenine pairs with Thymine, and Cytosine pairs with Guanine.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the difference between genotype and phenotype?

Back

Genotype refers to the genetic makeup, while phenotype refers to the observable traits.
