DNA contains a code for synthesizing proteins. Three nucleotides in a row code for a particular amino acid. There are four nucleotides in DNA, which are abbreviated as A, T, C, G. The amino acids are joined to form a protein.
Genetic mutations can occur in the DNA of individuals. Some mutations are harmful, some have no effect, and some might be beneficial to the organism. The table shows the nucleotide sequence of DNA that codes for a protein in one individual and the nucleotide sequence of the same segment of DNA in an individual with a mutation.
Which statement describes the most likely impact of the mutation in the mutated sequence shown in the image?
There will be no effect because the rest of the DNA is normal.
The extra nucleotide will be deleted before the protein is formed.
The protein formed will not be the same as that formed from the original DNA sequence.
The mutated DNA will code for the same number of amino acids as the original sequence.
Based on the given information, the most likely impact of the mutation in the mutated sequence is that the protein formed will not be the same as that formed from the original DNA sequence.
The mutation involves a change in the nucleotide sequence, indicated by the presence of an extra nucleotide in the mutated sequence. This alteration in the DNA sequence can cause a shift in the reading frame during protein synthesis, leading to a different sequence of codons and ultimately resulting in a different amino acid sequence.
As a result, the protein formed from the mutated DNA will have a different composition and structure compared to the protein formed from the original DNA sequence. Therefore, the most likely impact of the mutation is a change in the protein formed.

where does the excess glucose go once the liver & muscle glycogen stores are full?
When the liver and muscle glycogen stores are full, excess glucose is converted to fat and stored in adipose tissue or transported to other organs to be used for energy.
Excess glucose from dietary carbohydrates is stored in the liver and muscle as glycogen. Once these glycogen stores are full, excess glucose is converted to fat and stored in adipose tissue. This process is called lipogenesis. The fat that is produced is either stored or released into the bloodstream as triglycerides, which are transported to other organs, such as the heart, muscles, and other tissues. From here, the triglycerides can be oxidized and used for energy, or they can be stored in the form of fatty acids.

describe the structures involved in the production, transport, and secretion of oxytocin and vasopressin
The production, transport, and secretion of oxytocin and vasopressin involve several structures, including the hypothalamus, posterior pituitary gland, bloodstream, and target organs.
Oxytocin and vasopressin are two important hormones produced by the hypothalamus in the brain. The hypothalamus sends signals to the posterior pituitary gland to release these hormones into the bloodstream. The production, transport, and secretion of these hormones involve several structures, which are discussed below:
1. Hypothalamus:
The hypothalamus is responsible for producing oxytocin and vasopressin. It contains nerve cells that secrete these hormones, which are transported to the posterior pituitary gland for storage and release.
2. Posterior Pituitary Gland:
The posterior pituitary gland is a small structure located at the base of the brain. It stores oxytocin and vasopressin and releases them into the bloodstream when signaled by the hypothalamus.
3. Bloodstream:
Once released into the bloodstream, oxytocin and vasopressin are transported to their target organs, where they exert their effects.
4. Target Organs:
Oxytocin and vasopressin bind to specific receptors in target organs and stimulate various physiological responses. Oxytocin is involved in the contraction of the uterus during childbirth and the release of milk during breastfeeding. Vasopressin regulates water balance in the body and helps maintain blood pressure.
