ns. It should correspond to the transcriptome, although there can be differences of detail reflecting changes in the relative abundance or stabilities of mRNAs and proteins. Proteins may function independently or as part of multiprotein assemblies. If we could identify all proteinprotein interactions, we could define the total number of independent assemblies of proteins. 第 3章 基因的數(shù)目 Cvalue (C值 ) is the quantity of DNA in the genome (per haploid set of chromosomes). There is enormous variation in the range of Cvalues, from 106 bp for a mycoplasma to 1011 bp for some plants and amphibians. Nonrepetitive DNA (非重復(fù)序列 DNA) shows reassociation kiics expected of unique sequences. Repetitive DNA (重復(fù)序列 DNA) behaves in a reassociation reaction as though many (related or identical) sequences are present in a ponent, allowing any pair of plementary sequences to reassociate. 第 3章 基因的數(shù)目 第 1節(jié) 為什么基因組如此之大 ? 關(guān)鍵術(shù)語(yǔ) 第 3章 基因的數(shù)目 第 1節(jié) 為什么基因組如此之大 ? 低等真核生物的單倍體 DNA含量與形態(tài)學(xué)的復(fù)雜性相關(guān),而在高等真核生物中,變化很大。下圖為不同生物門類 DNA含量的分布
