21.3 Using Dna Sequencing

Question 1

How had analysing the genomes Of pathogens helped society

Answer 1

Doctors fund the source of infection
Doctors identify antibiotic resistant strains of bacteria ensuring they are only see when effective
Scientists track the progress of an outbreak of a potentially serious disease
Identify genetic markers

Question 2

How do scientists identify species in genome analysis

Answer 2

They identify particular sections of the genome that are common to all species but vary between them and so they can make comparisons
Aka dna barcoding

Question 3

What is proteomics

Answer 3

Study and amino acid sequencing of an organisms entire protein complement
It gives us increasing knowledge of extremely complex relationships between genotype and phenotype

Question 4

What are spliceosomes

Answer 4

When pre-mRNA is modified the Exxon’s are joined together by splicesomes to give mature functial mRNA
They join the exon in a variety of ways so a single gene may produce several versions of function mRNA

Question 5

What is synthetic biology

Answer 5

An emerging area is research that can broadly be described as the design and construction of artificial biological pathways

Question 6

What techniques are used in synthetic biology

Answer 6

Genetic engineering
Use of biological systems
Synthesis of new genes to replace faulty genes
Synthesis of an entire genome
