…………..proposed a model for protein synthesis with the help of DNA in bacterial cells.

Using recombinant DNA technology, genes from a donor cell can be inserted into a bacterium for DNA replication and protein synthesis. The kind of cells that can be used as gene donors in this technology are

(i) Repetitive DNA sequences are called microsatellites. (ii) Hershey could prove that proteins are the infective part of a virus. (iii) Antibiotics inhibit stages of bacterial protein synthesis in pathogenic forms. (iv) DNA to RNA to proteins is the central dogma in molecular biology.

A bacterial cell was transformed with a recombinant DNA that was generated using a human gene. However, the transformed cells did not produce the desired protein. Reason could be (a) Human gene may have intron which bacteria cannot process (b) Amino acid codons for humans and bacteria are different (c) Human protein is formed but degraded by bacteria (d) all of the above

Which of the following statements is/are not correct for single cell protein (SCP)? (i) The biomass is obtained from unicellular microorganisms only. (ii) It provides a protein rich supplement. (iii) They can be grown easily on materials like waste water from potato processing plants, straw, manure, sewage, etc. (iv) It helps to minimise environmental pollution. (v) SCP has to be processed before use.

Study the following statements regarding recombinant DNA technology and select the incorrect ones. (i) Taq polymerase extends the primers using the nucleotides provided in the reaction. (ii) Antibiotic resistance genes are considered as desirable genes in recombinant DNA technology. (iii) DNA fragments are separated according to their charge only, in agarose gel electrophoresis. (iv) Transformation is a procedure through which a piece of DNA is integrated in to the genome of a host bacterium. (v) To produce higher yields of a desired protein, host cells can be multiplied in a continuous culture. (vi) Downstream processing is one of the steps of polymerase chain reaction.

The questions below consists of statements of an Assertion and Reason. Use the following key to choose appropriate answer. If both assertion and reason are correct and reason is the correct explanation of the assertion If both assertion and reason are correct, but reason is not the correct explanation of the assertion If assertion is correct, but reason is incorrect If both assertion and reason are incorrect: Assertion : In prokaryotes. DNA is not scattered throughout the cell. Reason : DNA is help with some proteins in the nucleoid.
