Answer:
RNA.
Explanation:
RNA is present as genetic material in some viruses only. RNA is almost similar to DNA in its basic structure but contains oxyribose sugar and uracil instead of deoxyribose sugar and thymine.
According to RNA world hypothesis, RNA is the first genetic material evolved on earth. The RNA has the ability to store information as can be seen in process of transcription and translation. The ribozyme has the ability to acts as the enzyme. Hence, RNA has both ability to store information and catalyze the reaction.
Thus, the correct answer is option (E).
Yes, by a few days cats were created before man.
Answer:
D
Explanation:
Monosaccharides are simple units of carbohydrates
<span>An evolutionary tree can also be called a phylogenetic tree, or a just a phylogeny, and phylogenetics is the study of determining evolutionary relationships, or patterns of descent of organisms. Just like your family tree, an evolutionary tree indicates which ancestors gave rise to which descendants</span>
Answer: Gregor Mendel’s careful work with thousands of pea plants in the 1860 proved the blending hypothesis wrong and explained how inheritance really happens.
Mendel then crossed a true-breeding purple flower plant and a true-breeding white flower plant. This is called a monohybrid experiment. A test cross is performed between two plants that breed true for one trait, and the resulting trait for each offspring plant is determined
A chart of a monohybrid experiment between a purple and white flower
The first, true-breeding generation, is called the parent, P generation. The first generation of offspring, the first filial generation, is the F1 generation. Mendel found that these plants all had purple flowers. The F1 generation was crossed with itself. The next generation, F2 generation, had a 3:1 ration of purple to white flowers.
If the blending hypothesis was correct, the F1 generation should have all had light purple flowers. Instead, all the F1 plants had dark purple
The F1 plants all have one purple allele and one white allele . The genotype is the alleles for each gene in the plant. Here the genotype is Pp. A plant with two of the same alleles is homozygous. A plant with two
This inheritance model is explained using a Punnett square.
