Answer:
Site-directed mutagenesis
Explanation:
Site-directed mutagenesis (SDM) is a technique widely used in molecular biology in order to generate site-specific, targeted changes in the DNA sequence of a gene of interest. The SDM protocol consists of using a complementary oligonucleotide (primer) that contains the desired mutation, which hybridizes to the target DNA sequence and thus can trigger the desired mutation. Nowadays, the versatile CRISPR-Cas9 genome editing system is the most used technique to produce targeted mutations in any gene of interest.
I need them too , did you get the answers already ?
Answer:
The correct answer is - surface, proteins, and sugars.
Explanation:
Adhesins are the appendages present on the surface of the pathogen that help these pathogens to attach to the host cell and surface of the host. Adhesins are the components that are virulence factor these are present in both viruses and bacteria.
The adhesin component is generally made up of mainly of the proteins and sugars which help them to adhere to the cell of the host.
Thus, the correct answer is - surface, proteins, and sugars.
The placement of the genes on the parent chromosones - B.
<span>The reason for this is that if the parents of the kittens are heterozygotic individuals (Pp and Pp). Where P being one colour and p being another colour, it's quite possible that some of their litter have the pp allele combination which in turn could make them a different colour. </span>
