Genomics

Question 1

Why does transcription occur in one direction on the top strand and the opposite direction on the bottom strand

Answer 1

Strands are anti-parallel and transcription always goes 5’ to 3’

Question 2

Define genomics

Answer 2

Systemic study of whole sets of genes and their interactions within a species, as well as genome comparisons between species

Question 3

Define Bioinformatics

Answer 3

The science of collecting and analysing complex biological data, i.e. genetic codes

Question 4

Why sequence genomes

Answer 4

Discover genes that function in disease
Develop diagnostic tools
Determine genetic relatedness
Determine diversity, origins and evolution

Question 5

What is the aim of human genome projects

Answer 5

Sequence genome and identify all genes

Question 6

Define Metagenomic research

Answer 6

Study of genetic material recovered directly from environmental samples. high throughout sequencing of all species in the sample

Question 7

How is DNA sequencing analysed for the presence of genes

Answer 7

Analysis intron splicing in a eukaryote
Look into promoters and common control elements
Computer programs identify signals which may present a sequence of DNA
