Sections Of DNA Flashcards
During transcription, some sections of genome end up on _
mRNA strands (exons)
Genome sections that end up on mRNA strand are called exons, ones that don’t are called _
Introns
Most exons contain the code to make _
Protein
Function of introns is still debated but some may regulate _ (2)
Transcription
Gene expression
Introns lack of clear function led them to be labeled _
Junk dna
In humans, average 8.8 exons per gene which make up _ percent of genome
1
In humans _ introns per gene (24 percent of genome)
7.8
When exons are sequences exclusively, result is called an _
Exome
Intergenic dna are _
Sections between genes that don’t code for proteins
In humans _ percent of genome is intergenic
75
Minority of exons don’t code for proteins, instead contain regulatory elements that _
Aid in other processes
Introns may be result of evolution shuffling sections of genetic code, creating _
Spacers between coding stretches of DNA
Differences in sequence of bases within an exon give rise to different
Variants of genes (variety among species)
An intron can either be a section of dna or _
It’s corresponding section in the rna transcript
