Chromosomes are the homologous chromosomes that cross over
Answer:
The correct answer is D. How closely related the two species are to each other
Explanation:
Genome maps of every individual is unique. Genome map is the order of sequence of nucleotide which is present in an organism. Comparison of genome map allow the scientist to know how much closely related two organisms are.
The map of two individuals of the same species is almost the same. Similarly, the two same species have a more similar genome map than two distantly related species because they share most recent common ancestor.
For example, humans and chimpanzees are more similar than other apes so 96% of the genome are identical between them. So the right answer is D.
Answer:
The correct answer is DNA ligase.
Explanation:
DNA Ligase is an enzyme with links 2 strands of DNA by creating a bond between the phosphate group of 1 strand and deoxyribose group of the other strand of DNA.
In cells, it is used to join the Okazaki fragments together which are formed on the lagging strand during the process of DNA replication.
Okazaki fragments are tiny pieces of DNA nucleotide which are formed in a discontinued manner but latter they are joined by DNA ligase enzyme.
Answer:
A. by reacting animal fat or vegetable oil with water.
D. by treating animal fat or vegetable oil with hydrogen
Explanation:
Water is insoluble in animal fat or vegetable oil so it makes a layer on the surface of oil. When animal fat or vegetable oil react with hydrogen, it produces solid oil called ghee not biofuels. Biofuel is produced when animal fat or vegetable oil react with alcohol.
