Methylation involves chemical tags covering DNA, contributing to the

• epigenome
• epifactor
• epiforecast
• epidermis

The difference between DNA code and the epigenome is that the DNA code is

• flexible, while the epigenome is fixed for life
• fixed for life, while the epigenome is flexible
• determined by the environment, while the epigenome is not
• determined by one's stress level, while the epigenome is not

The complete instructions for making an organism, consisting of all the genetic material in that organism's chromosomes.

• genome
• epigenome
• genetic markers
• RNA codon

The process by which a cell becomes specialized for a specific structure or function.

• cell multiplication
• cell division
• mitosis
• cell differentiation

NGSS.HS-LS1-4

Protein molecules around which DNA is tightly coiled in chromatin

• Histones
• Whey
• Casein
• Hemoglobin

NGSS.HS-LS1-1

A chemical modification of DNA that does not affect the nucleotide sequence of a gene but makes that gene less likely to be expressed.

• methylation
• acetylation
• transcription
• translation

Which factor can affect the epigenome?

• nutrition
• exercise
• stress 
• all of these factors can affect the epigenome

what is an operon?

• a part of a ribsome
• a part of a Rna
• a unit made up of linked genes that code for proteins needed to do a specific task
• needed for dna replication

A protein that binds to the operator and blocks the RNA polymerase

• regulator
• repressor
• activator
• corepressor

The "on/off" switch for an operon is called the

• promoter
• repressor
• operator
• gene
