Solution

Question 1: Enhancer sequences for transcription activation in eukaryotes can exert effects from a great distance of the transcription target by forming loops or changing DNA structural elements.

Answer: True

Question 2: Eukaryotes are able to express different proteins over time or at certain points in the life cycle by using _____.

Answer: Silencers

Silencers: In genetics, a silencer is defined as a DNA sequence capable of binding transcription regulation factors, called repressors. DNA contains genes and provides the template to produce messenger RNA (mRNA). That mRNA is then translated into proteins.
