Unit 5 - SOL DNA Questions

Front

What is DNA and its role in organisms?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life. It determines the characteristics that will be inherited by offspring.

Front

What is the function of enzymes in DNA manipulation?

Back

Enzymes are organic molecules that catalyze biochemical reactions, including cutting DNA segments for genetic engineering.

Front

How do physical similarities between family members relate to DNA?

Back

Physical similarities often indicate that family members share a high percentage of proteins with the same molecular composition due to shared genetic information.

Front

What happens during DNA replication?

Back

During DNA replication, the double-stranded DNA molecule separates between specific base pairs, allowing each strand to serve as a template for new complementary strands.

Front

Where is hereditary information stored in a cell?

Back

Hereditary information is stored in the nucleus of a cell, which contains chromosomes made up of many genes.

Front

What are nucleic acids?

Back

Nucleic acids, such as DNA and RNA, are biopolymers essential for all known forms of life, responsible for storing and transmitting genetic information.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands of nucleotides twisted around each other, with base pairs connecting the strands.

Front

What are the four bases of DNA?

Back

The four bases of DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). A pairs with T, and C pairs with G.

Front

What is the significance of base sequences in DNA?

Back

The sequence of bases in DNA determines the genetic code, which dictates the synthesis of proteins and ultimately influences an organism's traits.

Front

What is a chromosome?

Back

A chromosome is a long, continuous thread of DNA that contains many genes and is found in the nucleus of eukaryotic cells.
