Elementary Medical Microbiology: please answer with explaination
The following pertain to ribosomes during protein synthesis except a. deliver the appropriate amino acid coded for in the mRNA codon b. participate only in translation. c. bind to the 5' end of mRNA by their small subunit. d. use their large subunit to supply enzymes for peptide bonding. e. shift to the right along the mRNA strand from one codon to the next. The DNA of microorganisms is made up of subunits called a. histones. b. amino acids. c. deoxyribonucleotides. d. mRNA e. polymerases. The process of making DNA from a DNA template is a. conservative synthesis b. carbon fixation c. DNA replication d. reverse transcription e. none of the above Which enzyme involved in the above processis charged with both proofreading and adding new bases? a. DNA primase b. RNA polymerase c. DNA polymerase III d. ligase e. topoisomerase II This 5' to 3' strand can be synthesized in a continuous fashion, without fragments. a. RNA strand b. primase strand c. leading strand d. lagging strand e. replicating strand
Ribosomes does all the functions in the given options except
carrying amino acids which is done by tRNA.
DNA is made up of deoxyribonucleotides units which contain
sugar, nitrogenous base and phosphate.
DNA synthesis from DNA molecule is called DNA replication.
DNA polymerase enzyme has the ability for proof reading as well
as polymerase activity.
Leading strand is the newly replicated strand which is
continuous in 5' to 3' direction.
