Summary Introduction

To determine:

The identification of strain of resistant or non-resistant M. tuberculosis.

Introduction:

The polymerase chain reaction is technique to amplify a piece of DNA very rapidly outside a living cell. It uses the same mechanism for multiplication of DNA as the cells use for DNA replication by using enzyme Taq polymerase (type of DNA polymerase).

Summary Introduction

The precaution should be taken in homeless shelters, mental health facilities, and jails to prevent transmission of TB.

Tuberculosis is a potential fatal caused by Mycobacterium tuberculosis which can infect almost all part of the body, but it mainly infect the upper respiratory tract in humans. The disease can be treated with antibiotic and certain drugs.

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW).  If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?
None
Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…
