Answer:
There should be 10% thymine
Explanation:
DNA bases come in specific pairs. Guanine pairs up with cytosine and adenine pairs up with Thymine.
According to the problem the DNA sample was 40% cytosine and 40% guanine, so this is correct, there are equal amounts of cytosine and guanine. Now Thymine needs to have equal amounts as adenine, but adenine only has 10%.
If we match up the amount of adenine to thymine, we would have 15% adenine and 15% thymine, but that would excede 100%. So you need to match the thymine to adenine.
10% adenine + 10 % thymine + 40% cytosine + 40% guanine = 100%
<span>You
are right in that bananas contain potassium and K-40 is a naturally
occurring potassium isotope AND the K-40 in an average banana does decay
at a rate of about 31 ATOMS per second (half-life is > 1 billion
years). This is an extremely low level of radiation and nothing to worry
about. Bananas will definitely NOT cause a "nuclear winter."</span>
a) ribosomes on the rough endoplasmic reticulum
mRNA (created by DNA) leaves the nucleus through the nucleic pores, and from there will enter a nearby ribosome since the rough endoplasmic reticulum is surrounding the nucleus. It is there that polypeptides are made and transported in vesicles to the Golgi apparatus because they cannot touch the cytoplasm when still incomplete. Hope this helped.
