What is DNA?

DNA stands for DeoxyriboNucleic Acid, a biological molecule found in the cells of all living things.

What is the structure of DNA?

DNA has a double helix structure made of two chemical strands twisted together.

How are the strands of DNA held together?

The strands are joined together by four different types of chemical bases.

Which bases pair together in DNA?

Adenine (A) pairs with Thymine (T), and Cytosine (C) pairs with Guanine (G).

What is a gene?

A gene is a small section of DNA in a chromosome that codes for a specific protein.

What is the role of the nucleus in a cell?

The nucleus contains chromosomes, which are long coils of DNA made up of many genes.

What is the genome?

The genome is one copy of all an organism's DNA, including the 23 pairs of chromosomes in humans.

What is the difference between continuous and discontinuous variation?

Continuous variation can take any value within a range (e.g., height), while discontinuous variation has distinct categories (e.g., blood group).

What is the importance of DNA?

DNA contains the genetic code that determines all characteristics of a living organism.

How far would all the DNA in a human body stretch?

If stretched out, all the DNA in a human body would reach approximately 9 million kilometers, twice the diameter of our solar system.

What is a chromosome?

A chromosome is a long strand of DNA coiled tightly, containing many genes.

What is the smallest unit of heredity?

The gene is the smallest unit of heredity, coding for specific traits.

How do you inherit characteristics from your parents?

You inherit characteristics through genetic material found in the nucleus of your cells.

What is the order of size from smallest to largest: cell, chromosome, gene, DNA, nucleus?

Gene < DNA < Chromosome < Nucleus < Cell.

What does the sequence of bases in DNA determine?

The sequence of bases forms a genetic code that determines the characteristics of an organism.

What is the function of a gene?

Each gene contains the information needed to produce a specific protein.

What is the chemical composition of genetic material?

Genetic material is made up of DNA, which contains all the information needed to make an organism.

What is the role of environmental factors in inheritance?

Environmental factors can influence characteristics, often interacting with inherited genetic factors.

What is a normal distribution in data?

A normal distribution is a bell-shaped curve that represents the distribution of a set of data.

How can you improve a method to produce a clearer normal distribution?

Improvements could include increasing sample size or ensuring consistent measurement techniques.

What is the significance of the double helix structure of DNA?

The double helix structure allows for the stability and replication of genetic information.

What is the role of bases in DNA?

Bases pair up to form the rungs of the DNA ladder, contributing to the genetic code.

What is the function of chromosomes in the nucleus?

Chromosomes organize and protect DNA, ensuring proper distribution during cell division.

What is the relationship between genes and proteins?

Genes code for specific sequences of amino acids to produce proteins, which perform various functions in the body.
