If a linear piece of dna has three sites for a particular restriction enzyme, into how many fragments will that restriction enzy
Kruka [31]

If a linear piece of DNA has three sites for a particular restriction enzyme, it will be cut into 4 fragments. If the DNA is circular, the number of obtained fragments will be N for N recognition sequences for the specified restriction enzymes however if the DNA is linear, the number of obtained fragments will be (N+1).

A bacterial protein called the restriction enzyme cleaves DNA at specific  locations. The recognition sequences, or short and distinct nucleotide sequences, are recognized by restriction enzymes in DNA. When a DNA sequence is recognized by the restriction enzyme, it hydrolyzes the bond between neighboring nucleotides and cleaves the DNA molecule.

The restriction enzymes guard against bacteriophages on the living bacteria. They identify the bacteriophage and cleave at its restriction sites, destroying its DNA.

The use of restriction enzymes in genetic engineering is crucial. In order to introduce foreign DNA for gene-editing purposes, restriction enzymes cut DNA at a specified location, which makes them a crucial tool.

Answer: Relevance

The scope of abiotic and biotic factors spans across the entire biosphere, or global sum

of all ecosystems. Such factors can have relevance for an individual within a species,

its community or an entire population. For instance, disease is a biotic factor affecting

the survival of an individual and its community. Temperature is an abiotic factor with the

same relevance.

Some factors have greater relevance for an entire ecosystem. Abiotic and biotic factors

combine to create a system or, more precisely, an ecosystem, meaning a community of

living and nonliving things considered as a unit. In this case, abiotic factors span as far

as the pH of the soil and water, types of nutrients available and even the length of the

day. Biotic factors such as the presence of autotrophs or self-nourishing organisms

such as plants, and the diversity of consumers also affect an entire ecosystem.

Influencing Factors

Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting

factors restrict the growth of populations. They help determine the types and numbers

of organisms able to exist within an environment.

Biotic factors are living things that directly or indirectly affect organisms within an

environment. This includes the organisms themselves, other organisms, interactions

between living organisms and even their waste. Other biotic factors include parasitism,

disease, and predation (the act of one anim
