Enhancers work by serving as binding sites for transcription factors--proteins that regulate transcription.<span> Enhancers lead to the production of regulatory proteins. The proteins bind to regulatory sites of DNA, triggering transcription of cell-specific proteins.</span>
Lets say that the genotypes are:
Male affected:XbY
Male unaffected: XaY
Female affected: XbXb
Female carrier: XaXb
Female unaffected:XaXa
P: XbY x XaXa
F1: XaXb XaXb XaY XaY The middle square is female carrier.
P:XbY x XaXb
F1: XaXb XbXb XaY XbY The left square is affected female.
P:XaY x XbXb
F1: XaXb XaXb XbY XbY The right square is affected male.
Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation
Answer:
B. Nearly every amino acid translated after the error will create the wrong protein after the deletion of a base.
Explanation:
Generally, mutations occur in two ways: 1) a base replacement, where one base is replaced for another; 2) insertion or deletion, where a base is either incorrectly inserted or deleted from a codon.
When a nucleotide is wrongly inserted or deleted from a codon, the effects of this change can be extreme. An insertion or deletion can affect every codon in a particular genetic sequence. For example, given the code:
GAU GAC UCC GCU AGG. It is the codes for the amino acids aspartate, aspartate, serine, alanine, and arginine. If the A in the GAU were to be deleted, the code would become GUG ACU CCG UAG G. It won't produce any right amino acid.
So, if the code becomes changes, it won't produce any amino acid or will produce the wrong amnio acid.
Answer:
The endocrine system is a chemical messaging network. Endocrine glands secrete hormones, which are carried by the circulatory system throughout the body. The primary endocrine glands are the pituitary, hypothalamus, pineal gland, thyroid, parathyroid, adrenal, pancreas, ovary, and testis. Hormones maintain homeostasis in the body.
