productive cell infection may be controlled at the membrane level‚ requiring the interaction of a specific cellular receptor with the virus envelope‚ as demonstrated recently for Epstein–Barr virus (EBV)1. Therefore‚ we have investigated whether the T4 molecule itself is related to the receptor for LAV. We report here that preincubation of T4+ lymphocytes with three individual monoclonal antibodies directed at the T4 glycoprotein blocked cell infection by LAV. This blocking effect was specific‚ as other

1. How DNA replication takes place? DNA replication occurs within the interphase‚ In this phase two strands of DNA serve as templates for new DNA strands that are forming. As the DNA separates a replication bubble is formed‚ this is where two replication forks are formed that grow in two directions. DNA polymerase creates new strands as nucleotides are added individually to each strand. As each nucleotide pairs itself to the complimentary nucleotide on the opposite strand‚ new DNA molecules are formed

determine the unknown DNA plasmid using restriction enzymes and conducting electrophoresis finally comparing the resulting fragments with the known restriction map. In this lab‚ it succeeds in showing the fragments. In this report we will discuss the‚ results‚ limitations and possible errors. Introduction In biology restriction enzymes are used in several ways to modify and manipulate DNA molecules. One common use is to compare pieces of DNA from one that is unknown‚ with fragments of DNA from another source

DNA FINGERPRINTING LAB REPORT DNA contains genetic material and information that makes up each individual trait. Every person can be identified by providing his or her genetic information based on a particular DNA strand. DNA information is an effective way of identifying persons if it is used properly. It is used to identify humans in different situations such as crime scenes‚ accident scenes‚ paternity testing‚ soldier remain identification‚ inheritance claims‚ missing person investigations‚

announced their landmark discovery: DNA exists in the form of a right handed‚ three-dimensional double helix. They described their DNA model as two DNA strands connected by hydrogen bonds between complementary bases. Adenine bases are always paired with thymines‚ and cytosines are always paired with guanines. Watson and Crick identified the anti-parallel configuration of DNA strands; each 5’ end of one strand is paired with the 3’ end of its complementary strand. Nucleotides are linked to each other
