Coenzymes

Coenzymes are small organic molecules that, themselves, do not function as catalysts (i.e. enzymes) but aid the latter in carrying out their functions. Enzymes are biological catalysts, which means that they allow reactions to occur at lower activation energies. In a way, enzymes help to "speed up" chemical reactions. 

Coenzymes are mostly derived from vitamins. Examples include TPP from Vitamin B1 (thiamine), FAD from Vitamin B2 (Riboflavin), and NAD+ from Niacin.

Transcription only occur in eukaryotic cells. Transcription and slicing both occur in the nucleus.

Explanation:

Transcription and splicing only occur in eukaryotic cells. Transcription and splicing both occur in the nucleus. Splicing of exons and intron removal is strictly a eukaryotic phenomenon. Prokaryotic genomes are smaller and do not contain introns. Both of these processes occur in the nucleus.

Part A If you want to affect chromatin packaging, which amino acid could you mutate to affect both histone acetylation and methy
attashe74 [19]

Answer:

Lysine

Explanation:

lysine residues on the histone tails of the octamer cn be activated by both acetylation and methylation patterns to influence accessibility or silencing of the genes respectiviely. for example, acetylation of H3K27 (histone 3 lysine residue 27) brings about a region of active chromatin allowing access to transcription activity while its trimethylation  will cause silencing of the associated gene at that particular area (no expression of that gene)
