domains can be combined in different and various arrangements to create proteins having different functions, and molecular evolution uses this as its basis. domains are believed to be genetically mobile units called modules. its C and N terminal are close to each other which allows them to slot into parent structures during evolution.
modular domain structure of proteins in eukaryotes basically allows to acquire new function in terms of evolution.
What does modular domain structure of proteins in eukaryotes allow for in terms of evolution?
If eukaryotes arose from within archaea, what does this mean in terms of the 'phyl' of archaea? Are they mono-, para-, or polyphyletic? How about eukarya?
How does the duplication of genes and /or genomes allow for the evolution of genomes?
How does the rearrangement of genes and/or genomes allow for the evolution of genomes?
Describe the various steps involved in the initiation of replication in eukaryotes. What proteins are involved in each of the steps, and when in the cell cycle does each of them occur? How does their temporal segregation contribute to the limitation of origin firing to at most once per cell cycle?
Which sentence does describe definition of tertiary structure of proteins? A. Tertiary structure of proteins is defined as amino acid sequence of their polypeptide chain(s) B. Tertiary structure of proteins is defined as regular set up of their polypeptide chain(s) to form a-helix or b-sheets. C. Tertiary structure of proteins is defined as spatial set up of domains of proteins linked by peptide bounds. D. Tertiary structure of proteins is defined as spatial set up of subunits of...
describe the structure of the catalytic domain of transpeptidase in terms of the numbers and types of the various secondary structure elements present and the way these are arranged to give tertiary structure
What is a disadvantage of the functional structure? Group of answer choices It does not allow firms to be either innovative nor flexible. It cannot effectively address a higher level of diversification. It does not allow firms to successfully pursue a blue ocean strategy. It does not allow firms to successfully pursue a cost-leadership strategy.
1. Define/differentiate the following from one another: Motif, Domain, Multi-domain, Quaternary structure 2. Define the following domains: SH2, SH3, Bromo, Chromo, PTB, SNARE, EF-Hand 3. Why are eukaryotic proteins on average bigger than prokaryotic proteins? 4. What is the role of protein domains, and why do most proteins contain more than one domain?
Proteins vary dramatically in structure; DNA strands are very similar in structure. How does this observation about differences in structure relate to differences in function between the two classes of biological molecules? How does the rather simple structure of DNA contain the information for such a complex and varied collection of proteins?
Where does replication stop? (Sites ves the proteins) What is a catenanes? What does topoisomerase do to allow for separation? What happens if the two chromosomes don’t separate?
