DNA

100

What is DNA?

the molecule that carries genetic information for the development and functioning of an organism.

200

What is DNA made of?

four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C)

300

How does DNA work

DNA's unique structure enables the molecule to copy itself during cell division.

400

How does the dna look like

The double helix

500

what is the purpose of DNA

contains the genetic information responsible for the development and function of an organism.

RNA

100

What is RNA

transcription and delivery of genetic instructions from the nucleus to the cytoplasm where proteins are made.

200

What is RNA made of?

a backbone made of alternating phosphate groups and the sugar ribose

300

How does RNA work

RNA is made to carry protein to the ribosomes

400

How does RNA look like?

A single strand 

500

What is the purpose of RNA

RNA carries out a broad range of functions, from translating genetic information into the molecular machines and structures of the cell to regulating the activity of genes during development, cellular differentiation, and changing environments.

Protein

100

What is a protein in cells?

the structure, function, and regulation of the body's tissues and organs

200

what is a protein made up of?

amino acids containing mostly hydrogen, carbon, nitrogen and oxygen

300

How does the cell protein work?

Proteins serve as structural support, biochemical catalysts, hormones, enzymes, building blocks, and initiators of cellular death.

400

What is the first step of a protein cell?

transcription

500

What is the main purpose of the protein cell?

determines its health and function

Chromosome

100

how many chromosomes do humans have?

46

200

What is a chromosome?

A structure found inside the nucleus of a cell

300

how does a chromosome work?

carry long pieces of DNA

400

How are chromosomes made?

Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure

500

what is the main purpose of chromosome

carry genetic information to be passed on from one generation to another

Plant Stages

300

what is the third stage of a plant stage?

Stem Elongation Or Rosette Growth And Shoot Development.

400

what is the fourth stage of a plant stage?

adult plant

500

what is the fith stage of a plant stage?

seed spreading
