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....
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....
RNA molecules can be broken up into three classes-which type of RNA molecule is translated into a protein sequence? Answer : Messenger RNA (mRNA). mRNAs are the RNA transcripts that contain protein coding sequences which are translated into protein....
AIDS virus has : (1) single-stranded RNA (2) double-stranded RNA (3) single-stranded DNA (4) double-stranded DNA Answer : single-stranded RNA...
RNA is composed of strands of nucleotides that are read as a 3 nucleotide codon. These are distinguished by tRNAs that match the codons on one end and carry individual building blocks of a protein chain. What are these building blocks of protein that tRNAs bind? Answer : Amino Acids...
