Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring
Answer:
In this modern age of science. Which of the following shows the most promise in production crops with a higher yield
A genetic engineering of crops plants
Answer:
Fish & algae
Explanation:
They are both biotic becuase they are living. Light & rocks are abiotic.
Answer:
- Restriction enzymes break a phosphodiester bond on both of the DNA strands.
- Two different linear DNA molecules are cut with a single restriction enzyme such that only one end of each molecule is cut and these ends have regions of single stranded DNA. The two different DNA molecules will have compatible ends.
Explanation:
Restriction enzymes are a type of enzyme that recognizes target DNA sequences and cuts them at these specific sites. These enzymes catalyze the hydrolysis of phosphodiester bonds by cleaving double-stranded DNA (dsDNA) sequences at specific sites on both DNA strands. There are restriction enzymes that generate sticky ends (cohesive ends), i.e., small stretches of single-stranded DNA (ssDNA) that self-ligate or ligate with a complementary region from another DNA molecule. Restriction enzymes that generate sticky ends are very useful in molecular cloning and DNA recombination techniques because they can hold two pieces of DNA together so that DNA ligase can covalently link them.
