1.1. Organization Of The Nucleus Flashcards
1
Q
Genome
A
Complete set of sequences in the genetic material of an organism
- includes the sequence of each chromosome plus any DNA in organelles
2
Q
Transcriptome
A
Complete set of RNAs present in a cell, tissue or organism
- it’s complexity is due mostly to mRNAs, but it also includes noncoding RNAs
3
Q
Proteome
A
The complete set of proteins expressed by entire genome
-> some genes code for multiple proteins
Therefore, size of proteome > no. Of genes
4
Q
Chromatin
A
(Only exists in eukaryotes)
-> DNA, Histone & non-histone proteins
5
Q
Heterochromatin
A
(Only in eukaryotes)
Highly condensed
Genes silenced
6
Q
Euchromatin
A
Less condensed
Genes transcribed
