Answer:
The percentage of other bases are: Thymine = 35%, guanine = 15% and cytosine = 15%.
Explanation:
There are four bases in DNA molecules, the bases are adenine, thymine, guanine and cytosine. The quantity of adenine and thymine are always equal, so also, the quantity of guanine and cytosine are always equal. Based on the information given in the question, Adenine = 35%, this implies that thymine too is 35%. The two bases added together give 70% , leaving only 30% for guanine and cytosine. Cytosine and guanine will share this equally and so each one of them will have 15%.

Answer:
internal receptor binding
Explanation:
This is because steroid hormones are lipids by nature (usually composed of cholesterol) so they are hydrophobic. This means that steroid hormones can easy pass through the membrane and bind to their internal receptors.
Internal receptors also known as intracellular receptors have DNA binding domain and when hormones bind to them DNA-binding site becomes exposed. Hormone-receptor complex gets into the nucleus and binds to regulatory regions of the DNA. Cellular response is gene expression.
The backlit screens of computers emit enough light to suppress the hormone melatonin. This hormone rises in the evening and orchestrates daily rhythms.
<h3>What is melatonin?</h3>
Melatonin is a hormone whose secretion in the brain is connected to sleep (i.e. the time of day or circadian cycle).
Melatonin is produced by the pineal gland as an environmental response to darkness.
This hormone (melatonin) is well known to be involved in different sleep disorders, thereby having therapeutic applications.
