<h2>Answer:</h2>
Bacteria provide genetic engineers with <u>_vector_ </u>and <u>_host_.</u>
<h3>Explanation:</h3>
Vector are vehicles or carriers which are used to carry the gene of interest. They are usually plasmids which are bacterial circular genome which can replicate independently.
Hence bacterial plasmids are used for the insertion of gene of interest and its transfer to the host cell.
As plasmids is taken from the bacteria, so mostly bacteria is used as the host for the gene of interest.
These segments of DNA that contain the code for specific proteins are called genes.
Actual coding region of DNA are called exons.
Explanation:
A segment of DNA that codes for one distinct protein is called a gene. Each chromosome carries thousands of various genes. The genetic code of the DNA ever prevails protected inside the nucleus.
a gene is a stretch of DNA. Nucleotide consists of a sugar, phosphate and a base.. Genes are organized and packaged in units named “chromosomes.” Humans have 23 pairs of chromosomes.
