Bioinformatics and Computational Biology Final Exam || With Questions & Answers (Graded A+) Bioinformatics and Computational Biology Final Exam || With Questions & Answers (Graded A+) What is Bioinformatics? - ANSWER - Bioinformatics is an interdisciplinary science to compile, store, and analyze/mine biological and medical data to help solve problems to improve human health and well‐being Differences between bioinformatics and computational biology - ANSWER - Bioinformatics focuses on ...

Earth's Structure - ANSWER-- Inner core is 6000°C made up of solid iron and nickel - Outer core liquid melted 2,000 Km thick - Mantle semi molten Asthenosphere - ANSWER-The upper semi molten part of mantle Lithosphere - ANSWER-The rigid mantle and crust Types of crust - ANSWER-- Continental- 30-70 km thick and less dense - Oceanic- 6-10 km thick and more dense Convection currents - ANSWER-- Lower parts of mantle rise as heated up, cool down become more dense and slowly sink - Circula...

Griffith's Transformation Experiment - S-strain: smooth, virulent - R-strain: rough, non-virulent - heat killed S-strain: non-virulent - heat killed S-strain + R-strain: virulent - live cells could be recovered form dead mice, living R-cells "transformed" by dead S-cells Avery, MacLeod & McCarty determined that DNA is the transforming principle Hershey & Chase - used radioactive material to label DNA and protein ->infected bacteria passed on DNA - helped prove that DNA is genetic materia...

Which of the following describes the way in which DNA is replicated? a) Dispersive Replication b) Conservative Replication c) Semi-Conservative Replication d) Leading duplication - Answer- c Which of the following is NOT true about replication points of origin? a) There can be 100s or 1000s of points of origin simultaneously in a eukaryote b) There are two replication forks formed at every point of origin c) The opening of a point of origin is so the DNA polymerase can fit between ...

What happens in prophase? - Answer -chromosomes condense and become visible -spindle fibres form -centrioles move to the poles -nuclear envelope breaks down What happens in metaphase? - Answer -chromosomes line up along the equator -spindle fibres attach to centromeres What happens in anaphase? - Answer -Spindle fibres contract and pull chromosomes apart at the centromere -identical sister chromatids are pulled to opposite polls What happens in telophase? - Answer ...

Similarities between eukaryotic and prokaryotic cells 1) Semi-conservative 2) Bidirectional Prokaryotic cells 1) Circular DNA 2) Single origin of replication Eukaryotic cells 1) Linear DNA 2) Multiple origins of replication New strands are always synthesized from: 5' --> 3' end of each strand Template strand is read: 3' --> 5' Chain extension occurs: by adding a dNTP to free 3' end of growing polynucleotide chain DNA polymerase DNA s...

You set up an experiment with yeast grown on lots of food (glucose) vs. very little glucose. Would you expect to see differences in the amount and make-up of tRNA between the two groups? - ️️No Your group is assigned to repeat Avery's experiments in BIOL 30 lab. You are given plates of R cells and tubes of the extracted S factor. In which of the following cases would you see the R cells be transformed into S cells. - ️️All of the above EXCEPT when you add S factor + DNAase Whic...
