Autism and Epigenetics

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

• genome

• epigenome

• genetic markers

• RNA codon

study of the inherited changes in gene expression, occurs without changing gene sequence and influence gene expression.

• genomics

• epigenetics

• bionomics

• fetal genetics

Which of these increases gene expression?

• methylation

• transcriptase

• helicase

• DNA acetylation

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

• methylation

• acetylation

• transcription

• translation

What is a gene?

• a segment of RNA that encodes for a protein

• a segment of DNA that encodes for a protein

• a chromosome

• your genome

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

• regulator

• repressor

• activator

• corepressor

Most gene regulation occurs at which step?

• translation

• signal transduction

• transcription

• DNA replication

What are the single stranded RNAs that bind to messenger RNAs and prevent translation into proteins?

• miRNAs

• tRNA

• mRNA

• DNA

What is the most common context in which DNA methylation occurs in vertebrates

• CpG methylation

• genomic imprinting

• histone modifications

• epigenetics

What are possible symptoms of Autism Spectrum Disorder?

• impaired cognitive abilities

• impaired physical abilities

• altered physical appearance

• seizures
