The nitrogenous bases guanine and adenine are A. purines. B. a phosphate group. C. pyrimidines. D. a sugar group.
AleksAgata [21]

Answer:

The nitrogenous bases guanine and adenine are A. purines.

Explanation:

Adenine and guanine are purines, whereas the other two bases in DNA (thymine and cytosine) are pyrimidines.  The main difference between purines and pyrimidines is the number of rings that the base has: purines have two rings while pyrimidines only have one ring.  

In addition, phosphate group and sugar group cannot be the answer to this question because these two elements in addition to a nitrogenous base makes up a nucleotide.

Hope this helps!

In Andalusian fowl, B is the gene for black plumage (head feathers) and B' (pronounced "B prime") is the gene for white plumage.
svet-max [94.6K]

INCOMPLETE DOMINANCE INHERITANCE:

<span>5.  In Andalusian fowl, B is the gene for black plumage (head feathers) and B' (pronounced "B prime") is the gene for white plumage.  These genes, however, show incomplete dominance.  The heterozygous (BB') condition results in blue plumage.  List the genotypic and phenotypic ratios expected from the following crosses:  a) black x blue  b) blue x blue  c) blue x white</span>

<span>6. </span><span>In snapdragons, petal color is determined by a single gene locus with two alleles making the "red" allele (R) incompletely dominant to the "white" allele (r).  Heterozygotes have petals, which are neither red nor white, but pink.  a) If a true-breeding red flower is pollinated with pollen from a white flower: What fraction of the seeds (F1 generation) would be expected to produce red-flowered plants?  What fraction of the gametes produced by the F1 plants would be expected to bear the R allele?  b) If two pink flowered plants are crossed, what genotypic and phenotypic ratios are expected among the offspring (F1 generation)?</span>

predict the effect of a mutation that prevents the expression of aurka on a normal (noncancerous) cell
earnstyle [38]

Answer:

Nowadays, if a cell cannot express the AURKA gene, malignant neoplasms or cellular malignancies can be generated.

since it is related to the KRAS gene.

There is some scientific evidence or research that maintains that FOSL1 acts on another gene, AURKA, whose expression to date was thought to be independently regulated by the KRAS oncogene, and for which clinical trials are currently underway with a drug that inhibits it. .

Explanation:

Aurora kinase A also known as serine / threonine-protein kinase 6 is an enzyme that in humans is encoded by the AURKA gene.
