The child has more of its genome inherited from the father d. Both genomes are inherited from the mother correct answersb. One from the mother and one from the father In humans, the male biological clock is ticking faster (T or F) correct answersTrue Single nucleotide polymorphisms (SNPs) are used as a tool in Molecular ...

Which of the following family of viruses have DNA genomes Correct Answer-Hepadnaviridae The single stranded negative strand RNA of a virus Correct Answer-must be converted to positive strand RNA in order to be translated into proteins The distinction between a prion and a virus is that Correct Answer-A prion is a single protein molecule whereas a virus may contain many copies of one or several proteins The Pasteur Swan Neck flask experiment shows that Correct Answer-microorganisms are p...

MCAT Biology Practice QuestionsHyperbaric oxygen may be used as a treatment for certain types of bacterial infections. In this therapy, the patient is placed in a which the partial pressure of oxygen is significantly increased, increasing the partial pressure of oxygen in the patient's tissues. This treatment is most likely used for infections with: A. obligate aerobic bacteria B. facultative anaerobix bacteria C. aerotolerant anarobic bacteria D. obligate anaerobic bacteria - correct an...

Portage Learning BIOD 171 Microbiology Lecture Exam Key 1-6 Exams 1. What are the two major types of nucleic acids and their roles? DNA- deoxyribonucleic acid RNA- Ribonucleic acid DNA- Cellular life has DNA and a role that DNA has is long-term storage of information, it holds the characteristics of living organisms. RNA- Is the carrier of information in form of amino acid sequence. It converts the information in the DNA and synthesizes proteins Tru...

BIOLOGY AQA AS 74011 PAPER 1 [WELL VERIFIED] • The human cell then makes a complementary strand to the HIV DNA. The complementary strand is made in the same way as a new complementary strand is made during semi-conservative replication of human DNA. Describe how the complementary strand of HIV DNA is made. - ANS---- there are complementary nucleotides/bases pair - DNA polymerase used - Nucleotides join together (to form new strand)/phosphodiester bonds form; Contrast the structures of ...

Helicase Ans- Catalyzes ATP-dependent unwinding of DNA double helices What is the helicase in E. Coli? Ans- DNAB Single-Stranded Binding Protein Ans- Binds to unwound strands of DNA to prevent reannealing DNA Polymerase Ans- Enzyme responsible for DNA replication Uses ssDNA as a template and makes a complimentary strand by polymerizing deoxynucleotides Synthesis in 5' to 3' direction List the DNA polymerases in E. Coli Ans- Pol I, II, III DNA pol I Ans- Removes RNA primers and f...

Predominant form of DNA - Right-handed B DNA and histone interaction is due to what type of bond? - Ionic What stains to the minor groove of DNA duplex? - SYBR Green What is the most abundant type of RNA? - Ribosomal RNA (rRNA) What does RNA act as in a retrovirus? - Genome and mRNA What increases half-life of mRNA? - 5' Methyl Cap What kind of DNA is most likely to be transcriptionally active? - Euchromatin What is the most common type of eukaryotic DNA? - Satellite DNA What specimen h...

Identify the different types of point (base substitution) mutations; missense, nonsense and silent mutations. POINT MUTATION: = A change in a single nucleotide Types: 1) Silent Mutation = When the redundancy of the genetic code kicks in and the change in that single nucleotide results in the same amino acid produced as the original code. 2) Missence Mutation = When the change in a single amino acid changes the amino acid produced 3) Nonsense Mutation = When the change in a single nucl...

Lab Report Format Expectations Utilize college level grammar and professional formatting when completing this worksheet. Pre-Lab Questions 1. Identify two differences between the composition of DNA and RNA. DNA takes the form of a double helix and is often described as looking like a long, twisted ladder with rungs. RNA is single stranded and shorter than DNA . It can fold back on itself due to hydrogen bonding to form a stem loop structure. 2. Suppose you are performing an experiment in ...
