Question

If a biology student wanted to find out about the genome of an organism, what is the best source of information to find it out? a. Wikipedia b. Google search c. NCBI related database d. pubMed The first cellular genome to be sequenced was a). Haemophilus influenzae. b) Escherichia coli. c) phi times 174. d). MS2. When comparing genes from Archaea, Bacteria, and Eukarya, which statement is true? a. Almost all archaeal genes are more similar to eukaryotic genes than to bacteria genes. b. Approximately half of archaeal genes are more similar to bacteria genes than to eukaryotic genes. c. Archaeal genes are almost universally unique; very few are similar to either eukaryotic or bacteria genes. d. Genes in Archaea involved in DNA replication, transcription, and translation are more similar to those of Eukarya, while those encoding metabolic functions other then information processing are more similar to those of Bacteria. What is the correct sequence of events to locate a possible gene in DNA sequence? a. List of probable ORFs. rightarrow Computer finds possible ribosomal binding site rightarrow Computer decides if ORF is likely to be genuine. rightarrow Computer finds possible start codons. rightarrow Computer finds possible stop codons. b. Computer finds possible start codons. rightarrow Computer finds possible stop codons. rightarrow Computer counts codons between start and stop. rightarrow Computer finds possible ribosomal binding site. rightarrow Computer decides if ORF is likely to be genuine. rightarrow List of probable ORFs. c. Computer finds possible start codons. rightarrow Computer counts codons between start and stop.. rightarrow Computer decimal if ORF is likely to be genuine. rightarrow List of probable ORFs. d. Computer finds possible ribosomal binding site. rightarrow List of probable ORFs. rightarrow Computer decides if ORF likely to be genuine. rightarrow List of probable ORFs. The most abundant genes in prokaryotic genomes are a. those involved in translation. B. those involved in DNA replication. C. those involved in transport. D. those involved in metabolism.

Explanation / Answer

Please find the answers below:

Part 1: Choice C (The NCBI-related database contains all the authentic and most comprehensive scientific information about an organism which can be accessed by any user globally to obtain relevant biological information)

Part 2: Choice B (E.coli, a simple rod-shaped bacteria was the first organism whose genome was fully sequenced by scientists)

Part 3: Choice D (Scientists have revealed that there is striking similarity between the molecular mechanisms of central dogma betweent the Archae and eukaryotes whereas there is a similarity between the other simple methods of information processing between archae and bacteria)

Part 4: Choice D (The ribosomal binding site will contain the whole open reading frame. This open reading frame will comprise of the start codon and stop codons along with the cistron. When accumulated in significant number, the in silico methodology indentifies many ORFs)

Part 5: Choice D (The bacteria contain many metabolic pathways for which they contain selective operons. Each metabolic pathway is regulated by a set of unique genes and hence, the bacteria have maximum number of genes related to metabolism)
