Homework Answers
5. All of the given options describe the RNA molecule the best. It contains uracil in place of thymine. It is single stranded containing ribose as a form of sugar.
Hence, the correct option is D.
10. The model of replication in which both the parental strands remain together following DNA replication is known as conservative mode of replication.
Hence the correct option is B.
11. All the given statements are correct about DNA replication. The DNA polymerase III performs the polymerization with precision, accuracy and high fidelity. It has proof reading capacity, which looks out for errors. Still, the enzyme has a error rate of one per 100 million nucelotide, which is very less.
Hence, the correct option is D.
12. The process of transcription produces RNA. Transcription is the phenomenon by which DNA changes into RNA in the nucleus of cell. In this process, thymine gets replaced by uracil. After the formation of RNA, protein is formed by the ribosomes.
Hence, the correct option is A.

Which of the following is a chemical or structural characteristic of RNA? The RNA sugar is ribose, which has an OH group on the 2' carbon. O RNA is usually a single-stranded molecule. The bases in RNA include uracil instead of thymine. RNA molecules are generally shorter in length compared DNA macromolecules. All of the above are either a chemical or structural characteristic of RNA. Which of these sequences could form a hairpin? 5' GGGGTTTTCCCC 3' 5' AAAAAAAAAAAA 3' 5'...

Which of the following occurs ONLY in eukaryotic cells and NOT in prokaryotic cells? RNA polymerase binds to the DNA template at the promotor sequence of the gene RNA polymerase is capable both of unwinding and separating the DNA helix - hence displaying part of the DNA template for transcription - and of catalyzing the formation of phosphodiester bonds. RNA polymerase pairs up Uracil (U) in the elongating RNA strand with Adenine (A) in the DNA template RNA polymerase pairs...

Matthew Meselson and Franklin Stahl performed an experiment using heavy isotopes and bacteria to determine which model DNA follows to replicate. Their results are evidence supporting which DNA replication model below? a. The parent DNA molecule is broken into its singular nucleotides from which new nucleotides are copied and then all nucleotides to come back together as one larger DNA molecule. b. The parent DNA is mixed into each of the daughter strands such that both daughter molecules contain a...

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...
