Dna And The Production Of Proteins

Question 1

What is a gene?

Answer 1

The basic unit of hereditary passed from parent to child.

Question 2

What is the function of DNA

Answer 2

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

Question 3

Describe the DNA structure

Answer 3

The DNA molecules is composed of two strands that are twisted together to form a double helix. This shape is held together by the complementary base pairs.

Question 4

Describe the complementary base pairing?

Answer 4

There are 4 bases that make up the genetic information: Adenine,thymine,cytosine,guanine. These bases match with one and other: A pairs with T and C pairs with G. The order of bases determines the order of amino acids and the order of amino acids determines the function and structure of protein

Question 5

Describe how a protein is synthesised in ribosomes

Answer 5

The ribosomes attaching the amino acids in the correct order to make a specific protein.
