Question

organisation of eukaryotic genes ​

Answer 1

Explanation:

Embedded in Nucleosome-complex DNA & Protein (Histone) structure that pack together to form chromosomes. Eukaryotic genome have unique features of Exon - Intron organization of protein coding genes, representing coding sequence and intervening sequence that represents the functionality of RNA part inside the genome.

Answer 2

Answer:

$\huge\boxed{\underline{\mathcal{\red{A}\green{n}\pink{s}\orange{w}\blue{e}\pink{r}}}}$

Gene expression in eukaryotes has two main differences from the same process in prokaryotes.

The typical multicellular eukaryotic genome is much larger than that of a bacterium.

Cell specialization limits the expression of many genes to specific cells.

The estimated 35,000 genes in the human genome includes an enormous amount of DNA that does not program the synthesis of RNA or protein.

$Genome Organization at the DNA Level:$

In eukaryotes, most of the DNA (about 97% in humans) does not code for protein or RNA.

1. noncoding regions are regulatory sequences.

2. introns.

3. repetitive DNA, present in many copies in the genome.

In mammals about 10 -15% of the genome is tandemly repetitive DNA, or satellite DNA.
