The genetic material of a cell carries the instructions for inherited features and processes, which are passed from parent to offspring.

Genetic material is made of a chemical substance called DNA.

DNA has a double helix structure made from two chains in a spiral.

The genome is all of the genetic material of a cell.

Scientists use models as simpler representations of complex things and ideas.

A model of the structure of DNA

Science

Pupils will learn about sexual reproduction in humans, including the structure and function of the male and female reproductive systems, menstrual cycle, gametes, fertilisation, gestation and birth.

In Year 6, pupils learned that living organisms produce offspring of the same kind, that characteristics are passed from parents to their offspring, and that offspring look similar to their parents and to one another but are not identical to them.

Heredity and DNA

Which one of these is **not** a feature of DNA?

Evaluating a model in science means to identify what?

DNA carries the {{}} that provides the instructions for all inherited features and processes.

DNA is a large molecule made up of smaller chemical units.

The genetic code is formed by A, T, C and G units that make up DNA.

The genetic code is like the letters that make words in an instruction booklet.

Choose which of the options below are analogies.

In this model of DNA, what feature is missing?

Which three of these cells store DNA in their nucleus?

The genetic material of all living organisms is in the form of a chemical molecule called ...

Which of these images are **not** a model of an animal cell?

Starting from the smallest, put these structures in order of size.

A chemical molecule that carries the genetic code.

Carried by DNA it gives instructions for inherited features.

It stores the DNA in animal, plant and fungi cells.
