Students have asked these similar questions
DNA sequences can act as "tape measures of evolution". Scientists analyzing the human genome sequence were surprised to find that some regions of the human genome that are most highly conserved (similar to comparable regions in other species) don't code for proteins at all. Given what you've learned about "genes" speculate on reasons why this might be so.
Fill the blank
New genes can arise during evolution through: (i) exonshuffling, which can alter the domain structure of proteins;(ii) duplication and divergence that generates gene families;and (iii)_______ mutations in intergenic DNA sequences.

https://healthland.time.com/2012/09/06/junk-dna-not-so-useless-after-all/
(Claim) Summarize scientist's error in naming noncoding DNA "junk" DNA. (Evidence) Is the amount of DNA an organism has correlated to intelligence or complexity? (Reasoning) What are two discovered uses of noncoding DNA (introns)?

- Concept 23. A gene is a discrete sequence of DNA nucleotides. This concept describes the discovery of the DNA sequencing technique that made modern biology and bioinformatics possible. The method was later used to sequence the human genome and genomes of many other organisms. This led to the accumulation of great numbers of nucleotide and protein sequences in the numerous databases. The concept 23 web page is here: http://www.dnaftb.org/23/ After reading the Concept page, answer the following questions. What was the Mendel’s definition of a gene? How was it different from the definition by Beadle and Tatum? Describe proteins based on the early sequencing efforts. What was the definition of a protein coding gene based on the genetic code? What are the beginning and ending codons of the gene’s protein coding sequence? What is the name of the method that makes use of a “defective” DNA nucleotide?

Where does life come from and what does it take to be alive? Recently, researchers have synthesized ribose- the sugar involved in the backbone of RNA- in the lab based on ice commonly found in space. Previously researchers had synthesized pyrimidine bases cytosine, uracil and thymine; parts of the DNA/RNA alphabet. While others have collected amino acids from meteorites. Think about all the different components that need to work to replicate DNA, create mRNA messages, and translate those messages into proteins for the cell to use. In this post you will reflect on the possibility that all these things have come together to create life somewhere other than on earth. In this discussion, pick a side (yes or no) and answer the following question: Do you think life in outer space is possible? If YES, what might it look like? If NO, why do you think it is not possible? Please remember to add a question to engage your classmates in the…arrow_forwardWhat is the central dogma of molecular biology? a.
