Answer:
The correct answer is e. All of the above.
Explanation:
Sister chromatids are made during the synthesis phase of the cell cycle. In the synthesis phase, the homologous chromosomes get replicated and sister chromatids are produced so they are produced by duplication of chromosomes.
As sister chromatids are produced by replication, therefore, they are identical copies of parent chromosomes. These sister chromatids are joined to each other at centromere. They get separated during the anaphase of mitosis and moves to the opposite pole.
Therefore the right answer is e.
The correct answer is d) kingdom.
Taxonomy is the branch of biology which deals in categorizing and naming of species. The modern taxonomic classification system consists of the eight taxonomic groups. These are Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. The domain is the most inclusive of the all taxonomic groups and species is the least inclusive. It is because every different species has a unique features. In this question domain is not in the option, thus Kingdom is the correct answer As it includes different Phylum, Class, Order, Family, Genus, and Species.
C , because Each strand of DNA acts as a template for synthesis of a new, complementary strand. Replication produces two identical DNA double helices, each with one new and one old strand.
Answer:
Option A) Double-stranded DNA
Explanation:
Note that the presence of thymine, a pyrimidine nitrogenous base in the genome indicates the presence of DNA.
Then, the summation of 28% adenine + 20% thymine + 35% cytosine + 17% guanine to yield 100% confirms that the DNA is double-stranded.
Thus, the structure of the viral genome is Double-stranded DNA.
