Answer:
13% cytosine
37% thymine
Explanation:
There are two types of nucleotides based on their structures - purines and pyrimidines.
The purines are adenine and guanine. The pyrimidines are thymine and cytosine.
Chargaff's rule states that the ratio of purines to pyrimidines in a molecule of DNA is 1:1
Therefore, the total number of A+G is the same at the total number of C+T.
All 4 bases together must equal 100% of the DNA molecule
If there is 13% guanine, and guanine always pairs with cytosine, there is also 13% cytosine.Together, that is 26% of the total sample.
100-26 = 74% of the total of adenine and thymine.
Since there are equal amounts of A and T, we know that the DNA sample is 74/2 = 37% thymine
Answer:
It involves alternating haploid and diploid phases. alternation of generations is the term that is used to the life cycle that happens in plants and algae.
Explanation:
Answer:
C.The gametophytes grow directly from the sporophyte
Explanation:
Conifers are gymnosperm which reproduce through the exposed seeds (seeds not included in fruits) found in the cones. The trees or plant on which these conifers grow are called sporophytes. In the sporophyte, the male and female gametes fuse together to form zygote which further develops into a seed. At the right time, these seeds get dispersed into wind and they grow into new plants known as sporophytes
