Heredity & DNA Flashcard

Front

What are the base pairs in DNA?

Back

Adenine pairs with Thymine, and Guanine pairs with Cytosine.

Front

What is a gene?

Back

A gene is a section of a chromosome that determines traits; it is a small segment of DNA.

Front

What shape does a DNA model typically represent?

Back

A double helix.

Front

What type of mutation involves the replacement of one base pair with another?

Back

Substitution mutation.

Front

What is the role of DNA in heredity?

Back

DNA carries genetic information that is passed from parents to offspring.

Front

What is the difference between genotype and phenotype?

Back

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

Front

What is the function of thymine in DNA?

Back

Thymine is one of the four nucleotide bases in DNA that pairs with adenine.

Front

What is the significance of guanine in DNA?

Back

Guanine is one of the four nucleotide bases in DNA that pairs with cytosine.

Front

How do mutations affect genetic information?

Back

Mutations can alter the sequence of DNA, potentially leading to changes in traits or functions.

Front

What is the structure of a chromosome?

Back

A chromosome is made up of DNA tightly coiled around proteins called histones.
