Front

What is Chargaff's rule?

Back

Chargaff's rule states that in DNA, the amount of thymine (T) equals the amount of adenine (A), and the amount of cytosine (C) equals the amount of guanine (G).

Front

What is the process of mitosis?

Back

Mitosis is a type of cell division that results in two identical daughter cells, each with the same number of chromosomes as the parent cell.

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

What does semi-conservative replication mean?

Back

Semi-conservative replication means that during DNA replication, each new DNA molecule consists of one original strand and one newly synthesized strand.

Front

What is the base pairing rule in DNA?

Back

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

Front

What is the role of DNA in living organisms?

Back

DNA carries genetic information essential for the growth, development, functioning, and reproduction of all living organisms.

Front

What is the significance of gametes in sexual reproduction?

Back

Gametes are reproductive cells (sperm and eggs) that combine during fertilization to form a new organism.

Front

What is the difference between asexual and sexual reproduction?

Back

Asexual reproduction involves a single organism producing offspring identical to itself, while sexual reproduction involves the combination of genetic material from two parents.

Front

What is the function of enzymes in DNA replication?

Back

Enzymes, such as DNA polymerase, facilitate the unwinding of DNA and the synthesis of new DNA strands during replication.

Front

What is the outcome of meiosis?

Back

The outcome of meiosis is four haploid cells, each with half the number of chromosomes of the original cell, leading to genetic diversity.
