DNA Structure and Replication

Front

What is the shape of DNA?

Back

The shape of DNA is referred to as a double helix.

Front

What is DNA replication?

Back

DNA replication is the process by which DNA makes a copy of itself before the cell divides.

Front

What is the name of the process where DNA copies itself?

Back

The process is called DNA Replication.

Front

What nucleotide sequence of bases pairs with TAGCTA?

Back

The nucleotide sequence that pairs with TAGCTA is ATCGAT.

Front

What does semi-conservative replication mean?

Back

Semi-conservative replication means that the new DNA has one old strand and one new strand.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides.

Front

What are the three components of a nucleotide?

Back

The three components of a nucleotide are a phosphate group, a sugar (deoxyribose), and a nitrogenous base.

Front

Name the four nitrogenous bases found in DNA.

Back

The four nitrogenous bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

How do the nitrogenous bases pair in DNA?

Back

In DNA, adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What enzyme is responsible for unwinding the DNA double helix during replication?

Back

The enzyme responsible for unwinding the DNA double helix during replication is helicase.
