SOL Biology/Day 7

Front

What type of bond joins nitrogenous bases in DNA?

Back

Hydrogen bonds are the type of bond that joins nitrogenous bases in DNA.

Front

Who discovered the process of transformation in bacteria?

Back

Griffith discovered that bacteria could be changed by the process of transformation.

Front

What is the phase of mitosis where chromosomes are separated and pulled to opposite sides?

Back

Anaphase is the phase of mitosis where chromosomes are separated and pulled to opposite sides.

Front

Who is known for taking the first picture of DNA using X-ray diffraction?

Back

Rosalind Franklin took the first picture of DNA using X-ray diffraction.

Front

What are the building blocks of DNA?

Back

Nucleotides are the units that are repeatedly joined together to form a strand of DNA.

Front

What is the role of hydrogen bonds in DNA structure?

Back

Hydrogen bonds hold the two strands of DNA together by connecting complementary nitrogenous bases.

Front

What is the significance of Griffith's experiment in genetics?

Back

Griffith's experiment demonstrated that genetic material could be transferred between bacteria, leading to the discovery of DNA as the genetic material.

Front

What occurs during telophase in mitosis?

Back

During telophase, the chromosomes arrive at opposite poles and begin to de-condense, and the nuclear envelope re-forms.

Front

What are the four nitrogenous bases found in DNA?

Back

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

Front

What is the function of nucleotides in DNA?

Back

Nucleotides serve as the building blocks of DNA, encoding genetic information.
