Session 1 We use the scientific method every day. Imagine your car doesn’t start one morning before school. Which of these is a reasonable hypothesis regarding the problem? I’m out of gas. A scientific theory explains what we know to this date about a natural event. Which of the following is a theory? There is molecular and biochemical evidence that all organisms are related. Choose the answer that best describes the sequence of the scientific method. observation‚ hypothesis‚ experiment‚ conclusion

discovered that RNA could perform both duties. In 2006‚ Ferris published a paper demonstrating that montmorillonite clay (which is present on Earth today and caused by volcanic activity) was an efficient catalyst for the formation of RNA oligomers from monomers under laboratory conditions (Ferris). Another important experiment indicated that RNA that has one type of catalytic properties can evolve to RNA that has another type (Walter and Engelke). Combined‚ these two experiments give evidence that RNA was

Chemistry (the etymology of the word has been much disputed)[1] is the science of matter and the changes it undergoes. The science of matter is also addressed by physics‚ but while physics takes a more general and fundamental approach‚ chemistry is more specialized‚ being concerned with the composition‚ behavior (or reaction)‚ structure‚ and properties of matter‚ as well as the changes it undergoes during chemical reactions.[2] It is a physical science which studies various substances‚ atoms‚ molecules

1) see figures 1-5 2) Proteins are polypeptide chains consisting of monomers called amino acids‚ which are made up of carbon‚ hydrogen‚ oxygen and nitrogen. Amino acids are made up of an amino group‚ an R group a carboxyl group and an alpha carbon‚ the different R groups of each individual amino acids determines which amino acid they will form. Amino acids bond through covalent peptide bonds this occurs via a condensation reaction‚ which is when one amino acids hydrogen & oxygen (carboxyl group)

Plastic mainly can be divided in two broader classifications namely. * Thermoplastics * Thermosetting plastics Both these varieties of plastics are not biodegradable that cannot

nitrogen-containing base‚ and a phosphate group. A pentose sugar is a five-sided sugar. Deoxyribose has a hydrogen atom attached to its #2 carbon atom (designated 2’)‚ and ribose has a hydroxyl group atom there. Deoxyribose-containing nucleotides are the monomers of DNA RNA Nucleotide [pic] The left picture shows the nucleotide unit of RNA. Nucleotides differ from nucleosides in that they have phosphate groups. Nucleotides can exist in the mono-‚ di-‚ or tri-phosphorylated forms

organisms. Nearly every cell in an organism’s body has the same DNA. DNA is the blueprint that guides the construction and development of living organisms. Some viruses have RNA as their genetic code. DNA structure DNA is a polymer‚ made up of many monomers called nucleotides which link together by condensation reactions. A nucleotide is composed of a pentose sugar called deoxyribose‚ a phosphate group and a nitrogenous base. Nucleotides link together by a phosphodiester bond. Four types of bases

1…………….ROLE OF MOLECULAR BIOLOGY IN THE 21ST CENTURY THE STATEMENT: Molecular biology of the 21st century‚ which says that the science devoted to elucidating the structure and function of genomes. On the other hand‚ the major advances gave rise to central dogma of molecular biology‚ comprising the three major processes in the cellular utilization of genetic information. The first is replication‚ the copying of parental DNA to form daughter DNA molecules with identical nucleotide sequences. The second
