Answer #1

1.DNA is called " not destiny" because in epigenetics, epigenome acts like a dimer switch or volume control, turning genes on or off, making them shout and whisper.

2. In ribozyme is spliced without proteins. Here only 3' OH of Guanine attacks the 5' phosphate and introns are cut out .

    Consider the structure of DNA and how it is passed on to new generations. Then consider the function of proteins like DNA polymerase. Now, based on the role proteins have in the process of DNA maintenance, replication, and/or new protein creation, discuss how proteins may be considered to play a vital role in the resulting inherited phenotype of an organism. Conclude with why DNA is still considered to be the primary source of heritable information.

    Alternative splicing is present in about 90% of human genes and can explain why our 20,325 genes can encode more than 1,000,000 proteins. Examine the image below of Gene X: Exon A Intron #1 Exon B Intron #2 Exon C 1. (2 pts) To create a transcript, which portions of this DNA sequence would be REMOVED during splicing? (Please be specific-ie. Exon A, Intron #2, etc.) 2. (3 pts) Gene X can encode 7 different proteins! Explain how this is...
