Why did DNA evolve for genetic storage if RNA preceded it? What is nDNA, cDNA, gDNA, cpDNA, mtDNA, and eDNA? If you were trying to create a cladogram that represented the evolutionary history of the genus Homo, would you be more interested in using aDNA, nDNA or eDNA? Why?

1. Describe the structure of the DNA molecule and how this structure allows for the storage of information, the replication of DNA, and protein synthesis. • What is the double helix? What are nucleotides, polynucleotide and base pairs? Use these terms to explain the structure of DNA. 2. List the similarities and differences between the various nucleic acid molecules. • What is semi-conservative replication of DNA? How does DNA get replicated?

1. Which of the following statements about the flow of genetic information is true? a. Proteins encode information that is used to produce other proteins of the same amino acid sequence. b. RNA encodes information that is translated into DNA, and DNA encodes information that is translated into proteins. c. Proteins encode information that can be translated into RNA, and RNA encodes information that can be transcribed into DNA. d. DNA encodes information that is translated into RNA, and RNA...

a. What is the difference between DNA and chromatin? Name one type of molecule that distinguishes these two forms of genetic information. b. What is a nucleosome, and what role does it play in cells? c. Why does DNA need to be compacted inside cells? d. Are any proteins used to keep DNA compacted other than proteins already present in chromatin?
Why would selection have favored ‘protocells’ that used DNA to store genetic information? Group of answer...
Why would selection have favored ‘protocells’ that used DNA to store genetic information? Group of answer choices DNA is more stable and has a lower mutation rate. DNA can evolve more quickly Because DNA cannot catalyze reactions DNA viruses are less harmful than RNA viruses. DNA viruses are less harmful than RNA viruses.

In a long double-stranded DNA molecule containing the genetic information for many genes, the template strand for one gene may be the nontemplate strand for another gene. true or false
Why are nucleotides a good molecule to make DNA out of, while amino acids are good...
Why are nucleotides a good molecule to make DNA out of, while amino acids are good for making proteins? A good answer will include: -how nucleotides compare to amino acids in terms of diversity of shape and feel -how the structure and funciton of DNA compares to the structure and function of proteins -what is the 'job' of DNA? why are the nucleotides good for allowing DNA to carry out its functions? what is the job of a protein? how...

What is the normal pathway from DNA to proteins? ____________ à _____________ à ____________ What do each of the arrows represent? Why do we say the genetic code is redundant and specific (not ambiguous)? How do you read the genetic code? Can you read a genetic code? Like what we did in class. What are the three (3) stages of transcription? Why is alternative RNA splicing a really neat process?

DNA is an informational molecule. It carries the information to build more DNA (replication) and it also codes from building and regulating all cell activities (gene expression). The information is encoded in a nucleotide code. The code is translated on Ribosomes that are protein making factories in cells. Remember ALL cells have DNA, RIBOSOMES and Proteins. This concept is called:
