How would you prove that DNA is the storage molecule for genetic information? Why not proteins?...
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?
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 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...
15. Explain why many scientist originally believed that proteins were the carriers of the genetic information?
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:
How is DNA similar in prokaryotic and eukaryotic cells? a. In both cells, DNA is a double helix b. In both cells, DNA contains the genetic information on how to make proteins for various life functions c. In both cells, ribosomes are needed to translate the information in DNA into proteins d. In both cells, DNA is made of the same bases e. All are correct
Assuming that you start with one template DNA molecule, how many total DNA molecules would you have after 30 cycles? O 6.48 x 105 060 0 1,073 O ~1.07 x 109 Submit Answer Tries 0/99
