E. How many nucleotides would be required to generate a polypeptide that is 15amino acids long? This requires knowing how many nucleotides of DNA code forone amino acid.F. Assuming that there are between 20,000-25,000 genes in the human genome, doyou think there are 1) fewer, 2) approximately the same number, or 3) moreproteins in the human genome? Explain your answer.

Why do humans have such a large number of nucleotides (3.2 billion base pairs) compared to the number of nucleotides in the Japanese pufferfish (with only 400 million base pairs)? the difference is due primarily to a relative abundance of intron nucleotides in humans the difference is due primarily to a relative abundance of euchromatin sequences in humans the difference is due primarily to a relative abundance of intron sequences in humans the difference is due primarily to a relative abundance of protein-coding genes in humans the difference is due primarily to a relative abundance of exon sequences in humans
. The following data represent the base compositions of double-stranded DNA from two different bacterial species and their RNA products obtained in experiments conducted in vitro:a. From these data, determine whether the RNA of these species is copied from a single strand or from both strands of the DNA. Draw a diagram to show how you solve this problem. b. How can you tell if the RNA itself is single stranded or double stranded?
By average, how many Sau3A (5’GATC3’) sites are there in a 10 kd DNA molecule? (1/4)^6 * 10,000 = 2.44140625 => 2.4 For the above 10 kb DNA, if you use Sau3A to do a complete digestion, you will only get a lot of small fragments ( 200~500 base pairs). What should I do if I want to get larger digested fragments (say 3 to 5 kb) Please answer asap and type your answer and do not copy from anywhere please

In the Meselson and Stahl experiment. E. coli cells grown on heavy nitrogen were transferred to light nitrogen. What % of DNA can be expected to be constituted of light nitrogen after 4th generation of multiplication? Explain your answer with the relevant theories of molecular biology.
The A+T: G+C ratios in the DNA of cattle and rats are very similar. Would you expect the tRNAs, rRNAs, and mRNAs of the two species to be very similar? Explain. GIVE THE BEST ANSWER.
You are characterizing a DNA-binding protein, and have used genetic experiments to identify a domain required for the interaction of the protein with DNA. Your secondary structure analysis software predicts that the domain forms a β helix, but you are unconvinced. What experiments could you perform to confirm the presence of a β helix in this region?
Based on our modern understanding, what revisions are necessary to the original one-gene / one-enzyme hypothesis? (Check all that apply.) Alternative splicing allows one gene to encode multiple polypeptides. Some genes encode RNAs, not enzymes. Some genes encode lipids, not enzymes. Some genes encode polypeptides that are not enzymes, such as structural proteins. Proteins as functional units may be composed of several polypeptides, so genes may encode just one polypeptide within a larger protein. Enzymes are not encoded by genes after all — they are constructed through separate biochemical processes.
Compute the [A + C]/[T or U] +G] ratios of the DNA and RNA models. Do you expect the same values for other DNA and RNA models that will be constructed, for instance? Why? A= 3 T=3 U=2 C= 4 G= 4
Given: eukaryotic cells can make different proteins, using only one gene. How can a eukaryotic cell make different final proteins from the same gene? Note: some of the answers are actually correct statements, but they don't have anything to do with this question. A.Eukaryotes have 3 RNA polymerases instead of just one. B.Eukaryotes cannot perform simultaneous transcription and translation. C.Eukaryotes splice RNA and can do so in various arrangements. D.Eukaryotes lack the Shine Delgarno sequence.
In relation to central dogma of molecular biology answer the following questions: Imagine that the mRNA codons consisted of only two nucleotides instead of three nucleotides. Would there be a sufficient number of codons for all twenty amino acids? Explain your answer.
Consider the expression “central dogma,” which refers to the flow of genetic information from DNA to RNA to protein. is the word “dogma” appropriate in this context?
