The periodic table only accounts for elements. It does not account for compounds, such as water.
Answer:
If a strand of DNA contains the bases adenine, cytosine, cytosine and guanine the order of the bases on the opposite strand is thymine, guanine, guanine and cytosine.
Explanation:
DNA contains a double strand, each of which contains a specific sequence of bases —adenine, thymine, cytosine and guanine— whose order determines the genetic information stored in this nucleic acid.
The sequence of bases on one DNA strand is complementary on the other strand, taking into account the complementarity of bases, i.e. the purines adenine and guanine are complemented by the pyrimidines thymine and cytosine, respectively:
A = T
G ≡ C
<u>So that the sequence A - C - C - G of one chain is complemented by the sequence T - G - G - C of the other</u>.
<em> Taking into account the above information, the other options can be discarded, as they do not comply with the complementarity of bases in the DNA.</em>
They would have to use micro dissection instruments
Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.
So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes
