Question 1

What type of large organic molecule is DNA made of?

Answer 1

Nucleic acid

Question 2

What functions do proteins have?

Answer 2

Every time we move contractile proteins in our muscles are making this possible

Multicellular organisms have a complex communication systems in which specific messenger proteins (such as hormones) deliver important information, enabling the organism to function and survive

Transporter proteins act to transport other molecules both within cells and between cells

Proteins can provide structure working an organism or act as catalysts to help processes (such as digestion in our stomachs)

Question 3

What are the 4 different types of large organic molecules?

Answer 3

Lipids, carbohydrates, proteins, nucleic acids

Question 4

What are the building blocks of proteins called?

Answer 4

Amino acids

Question 5

How many building blocks of proteins are there?

Answer 5

There are 20 building blocks of amino acids

Question 6

What elements are proteins mostly made from? (4)

Answer 6

Carbon, hydrogen, oxygen and nitrogen

Question 7

What type of proteins allow movement and are found in muscles?

Answer 7

Contractile proteins

Question 8

What type of proteins are hormones?

Answer 8

Messenger proteins

Question 9

What type of proteins speed up chemical reactions in organisms?

Answer 9

Enzymes

Question 10

What type of proteins bind to other molecules and transport them within cells?

Answer 10

Transporter proteins

Question 11

What is the change in structure of a protein in response to temperature or PH called?

Answer 11

Denaturation

Question 12

What are the four letters used in a DNA code?

Answer 12

A, T, C, G

THEY REPRESENT 4 bases

Adenine, thymine, cytosine, guanine

Question 13

What are genes?

Answer 13

They are the bases within a DNA strand that comprise a particular order and convey a particular meaning.

They contain specific information

The DNA molecule is a linear sequence of base pairs and genes are shorter linear sections

It is a short section of a long DNA molecule

Question 14

The human genome has gore many genes?

Answer 14

25000

Question 15

What is a trait?

Answer 15

It is another way of referring to a characteristic such as eye colour or flower colour

Question 16

What part of the cell is DNA contained in?

Answer 16

The nucleus

Question 17

What are the complex units called that DNA is packaged in to?

Answer 17

Chromosomes

Question 18

What shape do chromosomes form?

Answer 18

Double helix

Question 19

What ways can you summarise key points?

Answer 19

Billeted list
Mind maps
Key words
Short summary paragraph 
Diagram 
Summarising in a table and

Question 20

What are genes made of ?

Answer 20

Nucleotides

Sugar
Phosphate group
Base (A,T, G,C)

Question 21

What is he one gene-one protein hypothesis?

Answer 21

It is the relationship between a gene and the protein it codes for.

There is a direct and specific relationship between the linear sequence of base pairs that makes up a gene and the linear sequence of amino acids in a protein molecule

Question 22

How do genes and proteins have a relationship?

Answer 22

Each gene code has the direct instructions to build a specific protein that has a specialist role and a unique chemical structure

Question 23

What additional molecule is involved Int he process of protein synthesis by DNA?

Answer 23

RNA
Ribonucleic acid

This is an intermediary molecule
