Chromatin has two different regions, euchromatin and heterochromatin. One of these regions is highly condensed and considered an inactive region whereas the other is less condensed so it is more ... for transcription. Which of these regions would contain genes that are being transcribed often? Answer : Euchromatin. Euchromatin is less condensly packaged allowing for easier access by transcription factors and polymerases. Heterochromatin is a region of condensed packaging and considered an inactive region....

The structure of DNA is a double helix formed by two strands of DNA sequence. This sequence consists of 4 different nucleotides- Adenine, Thymine, Cytosine and Guanine. How do the nucleotides on one strand interact with the nucleotides on the second strand to maintain the helical shape of DNA? Answer : Complementary Base Pairing. Adenine complementary base pairs with Thymine and Guanine complementary base pairs with Cytosine....
