What allows the peaks to be different colors?
You are provided with a sample of aardvark DNA. As part of your investigation of this DNA, you transcribe mRNA from the DNA and purify it. You then separate the two strands of the DNA and analyze the base composition of each strand and of the mRNA transcripts. You obtain the following results: A G C T UDNA strand #1 19.1 26.0 31.0 23.9 0DNA strand #1 24.2 30.8 25.7 19.3 0mRNA 19.0 25.9 30.8 0 24.3Which strand of the DNA is the “sense” strand that serves as the template for mRNA synthesis?
Which of the following are possible base compositions for double-
stranded DNA?
O A=30% G=20% C=20% T=30% U=0%
O A=20% G=35% C=35% T=20% U=20%
O A=30% G=20% C=35% T=15% U=0%
O All are correct

- Shown is a sequencing gel. Read the sequence off the gel and determine the first 4 nucleotides (or bases) based on the fact replication occurs 5¹ to 3¹. A I G C Answer:arrow_forwardIn this activity you will extract DNA from living material. Before you begin, here are some helpful suggestions. 1 Make the extraction buffer first and keep it in the refrigerator until you are ready to use it. To make the extraction buffer, add 2 teaspoons of detergent, 1 teaspoon of salt, and ½ cup of water to one of the plastic cups. Stir well, and refrigerate or let stand in an ice bucket. 2 Keep the alcohol ice cold until you are ready to use it. 3 Try to move through each step of the activity as efficiently as possible. In addition to DNA, smashed-up fruit also contains enzymes that chop up DNA if it sits at warm temperatures for too long. Procedure 1 Remove any of the green stems or leaves on the strawberry (if using a banana, remove the peel). 2 Place fruit into the plastic bag. Seal the bag and gently mash up the fruit with your hands for two minutes. What does this mechanical action do to the cells and the DNA?arrow_forwardA DNA strand was sequenced using the Sanger method (https://www.youtube.com/watch?v=KTstRrDTmWI). The reaction tube contained the DNA strand, fluorescently labelled dideoxynucleotide triphosphates (ddATP – yellow, ddGTP – green, ddCTP – blue, ddTTP - red), deoxynucleotide triphosphates, DNA polymerase, or its Klenow fragment.
