Dna and the central dogma - Study guides, Class notes & Summaries

LIFESCI 2G03 Test 1 Questions and Answers Already Passed Question: What is the main function of enzymes in biological systems? Answer: Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to proceed. Question: How does the structure of DNA enable it to carry genetic information? Answer: DNA's double-helix structure, composed of nucleotide pairs (adenine with thymine and cytosine with guanine), allows it to store and...

TEST BANK FOR ESSENTIAL CELL BIOLOGY 5TH EDITION BY BRUCE ALBERTS, ALEXANDER D JOHNSON, DAVID MORGAN, MARTIN RAFF, KEITH ROBERTS, PETER WALTER ISBN 9780393691092 Living systems are incredibly diverse in size, shape, environment, and behavior. It is estimated that there are between 10 million and 100 million different species. Despite this wide variety of organisms, it remains difficult to define what it means to say something is alive. Which of the following can be described as the smallest liv...

BIO 201- Exam 1- Ch. 1-6- Rio Salado Questions and Answers Already Passed What is the basic unit of life in all living organisms? The basic unit of life in all living organisms is the cell. What is the function of ribosomes in a cell? Ribosomes are responsible for protein synthesis in a cell. What is the role of mitochondria in eukaryotic cells? Mitochondria are known as the powerhouses of the cell, as they produce energy in the form of ATP through cellular respiration. Wha...

List the major steps of the "central dogma" of molecular biology. What are the products of each step? Correct Answer-Replication --> DNA Transcription --> RNA Translation --> protein Once the DNA strands unwind and separate, DNA polymerases copy the DNA. What are they copying? What characteristics of DNA necessitates the need for leading and lagging strands to copy the DNA? Correct Answer-They are copying ____. DNA is antiparallel so the mode of synthesis occurs in 2 different ...

MCAT Biology Central Dogma - correct answer DNA → RNA → Protein Purines - which bases? - how many rings? - correct answer Pyrimidines - which bases? - how many rings? - correct answer Remember: "Pyrimidine" has a "y" in it; so does "cytosine" and "thymine." Phosphodiester Bond - correct answer Joins one nucleotide to the next; between the 3rd C of one ribose and the 5th C of the other to create the sugar-phosphate backbone Directionality of DNA (convention) - correc...

How does information flow? From DNA to RNA to protein What information is central to modern biotechnology? The use of methods to study and manipulate information about the central dogma. What is the exception to the central dogma? The transcription of RNA into DNA using reverse transcriptase. How does the cycle of the central dogma work? Instructions of DNA are transcribed onto messenger RNA. The ribosomes are able to read the genetic information inscribed on a strange of the ...
