Question
Chapter 1, Problem 28P
Interpretation Introduction
Interpretation:
The number of possible different cell types if each cell expresses 10 sets of the genes should be calculated.
Concept introduction:
The study of epigenetic variation or modifications in a set of genomes is termed as the epigenomics. Epigenetic modifications do not alter the DNA sequence but affects the gene expressions. Moreover, it is reversible modification in the cell’s DNA or histone sequence.

True or false?: The CTD is responsible for mRNA-processing steps that are specific for mRNA and not for other forms of RNA. Explain why you chose true or false.
Protein expression:
Given that we control the composition of the medium in which we grow our bacteria, are there any additional advantages of recombinant expression of proteins compared to using chemical synthesis?
Central Dogma of Molecular Biology from DNA to RNA to Protein, discussing the principles underlying the transfer of information in a biologic system and its regulation.
However, recent research seems to challenge certain aspects of Crick’s Central Dogma.
Does the Central Dogma still stand today? If not, can you find an example for a type of information transfer that is not explicitly covered by the Central Dogma (or even violates it)?
