Sharing assignments in OpenClass
OpenClass is on a mission to improve & democratize education. Through our platform, educators can share assignments privately or with our entire community to improve accessibility of the best learning resources around the world.
Our assignments guide students through research-backed study sessions to reinforce learning. If this review is relevant to your teachings, feel free to add it to one of your classes!
Our format is simple and engaging: students are asked a retrieval question, then shown corrective feedback and a multiple-choice mastery question to assess their understanding of the material. Assignments adapt to unique student needs and continue to draw questions until a student has demonstrated mastery.
Describe the three main components of a nucleotide and explain their roles in forming the structure of DNA and RNA.
Explain how complementary base pairing works in DNA and why it is essential for DNA replication.
Compare and contrast the structures of DNA and RNA, focusing on their nucleotide components and overall structure.
Explain the role of hydrogen bonds in the structure of DNA and how they contribute to the stability of the double helix.
Describe the process by which nucleotides are linked together to form a nucleic acid strand, including the type of bond involved.
Describe the process of DNA replication and explain its significance in the flow of genetic information.
Explain the process of transcription and its role in the flow of genetic information.
Describe the process of translation and its importance in the flow of genetic information.
How do mutations in DNA affect the processes of transcription and translation?
Explain the significance of the central dogma of molecular biology in understanding the flow of genetic information.
Describe the structural differences between DNA and RNA and explain how these differences impact their respective functions in genetic expression and regulation.
Explain the role of mRNA in the process of protein synthesis and how it differs from the role of DNA.
Compare the roles of tRNA and rRNA in the process of translation.
Discuss how the regulatory roles of DNA and RNA differ in gene expression.
Explain how mutations in DNA can affect RNA and subsequently protein synthesis.
Describe the structural differences between DNA and RNA and explain how these differences impact their respective functions in genetic expression and regulation.
(Student response here)
DNA is a double-stranded molecule with a long chain of nucleotides, while RNA is typically single-stranded. DNA contains the sugar deoxyribose, whereas RNA contains ribose. DNA uses the bases adenine, thymine, cytosine, and guanine, while RNA uses adenine, uracil, cytosine, and guanine. These structural differences allow DNA to store genetic information stably and RNA to be more versatile in functions such as coding, decoding, regulation, and expression of genes.
Which of the following is a structural difference between DNA and RNA that impacts their function?
DNA is double-stranded, while RNA is single-stranded.
DNA is single-stranded, while RNA is double-stranded.
DNA contains ribose, while RNA contains deoxyribose.
