Test 1 Flashcards
What is genomics
The study of organization, function and evolution of genomes
Where are human genomes found
The nucleus
What are open reading frames
codons in a gene that encode the amino acid of the gene
What starts an open reading frame
Promotor
What is the human genome project
A project designed to publish the entire sequence of the human genome
What years the the HGP run
1990s-2003
What did the HGP accomplish
Basic sequence of human genome 3x10^9
what are introns
parts of an amino acid sequence that are dropped from translation…found between eons
what are exons
nucleotide sequence that remains in sequence through translation
alternative splicing
introns are dropped and exons are used to make protein
what is a gene and how many are in the human genome
- most basic unit of genetics
- approx 20-25000
What does non-gene dna do
it is unclear what it does
why are only 450/1700 b-hemoglobin genes expressed
when introns are dropped you are left with hemoglobin
What is the process of making rna called and where is it done
In the nucleus
-transcription
what are the inputs of transcription
RNA polymerase
What are the outputs of transcription
polypeptides
after RNA is made what is the process that follows
translation
what are the products of these processes used for
differentiating different cells
What is the largest and smallest chromosome
1=largest
21=smallest
What is the largest class of genes
the unknown sector
What is a genetic map of human chromosomes
order of chromosomes and showing distance between them
how is a genetic map made
by probes which let us know specific genes
where does transcription take place and what is it
DNA-> RNA
-in the nucleus
where does translation take place and what is it
RNA->proteins
In the cytoplasm
