Frequent question: What vectors were used in the Human Genome Project?

Efficacy of nilotinib for first- and second-line treatment of CML

Which are the commonly used vectors for human genome sequencing?

Complete answer: Currently, the most commonly used vectors are BAC or bacterial artificial chromosome. These have been created from F-plasmids which are involved in bacterial conjugation, and can carry up to 300 kbp of foreign, inserted DNA. Yeast artificial chromosomes or YACs can carry even more, up to 1000 kbp.

Which vector is extensively used in the analysis of genomes including human genomes?

Today most cloning is performed with plasmid vectors. The plasmid vectors most widely used for gene cloning are small circular molecules of double-stranded DNA derived from larger plasmids that occur naturally in bacterial cells.

Which of the following is commonly used as a vector for introducing a DNA fragment in human lymphocyte?

Retrovirus is commonly used as vector for introducing a DNA fragment in human lymphocyte.

What were the two major approaches used to sequence human genes in Human Genome Project?

HGP involved two major approaches: Expressed Sequence Tags (ESTs) – This approach focussed on identifying all genes expressed as RNA. Sequence Annotation – This blind approach involved sequencing the whole genome (coding and non-coding) and later assigning functions to the different regions.

What were the four main goals of the human genome project?

-Sequencing the whole genome. -Creating genome sequence databases to store the information. –Identification of the entire human genome. -Taking care of the legal, ethical, and social issues that the project may pose.

What are plasmids and vectors?

A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell’s chromosomal DNA. … Plasmids that are used experimentally for these purposes are called vectors. Researchers can insert DNA fragments or genes into a plasmid vector, creating a so-called recombinant plasmid.
