The first stop in assessing the evolutionary path of the three equine species is to transcribe their mitochondrial DNA to RNA. A mitochondrial gene from a horse is found on the top strand: What RNA sequence is produced from this strand of DNA? (Enter your answer beginning at the 5' end with no spaces.)
The RNA sequence produced from the top strand of the mitochondrial DNA of a horse is: 5'-AAUCUGCUUGGCCUAAAU-3'.
This sequence is derived from the process of transcription, which is a part of gene expression. In transcription, the DNA sequence is used as a template to create a complementary RNA molecule. The RNA molecule created from the mitochondrial DNA of the horse contains the same genetic information, but it is written in a different language.
In the process of transcription, DNA is unzipped, and an enzyme called RNA polymerase binds to the template strand of the DNA and starts reading it in the 3' to 5' direction. For each DNA nucleotide, an RNA nucleotide is matched to it and the two nucleotides are held together by a hydrogen bond.
This process continues until the enzyme reaches the end of the template strand. The result of this transcription is a single strand of RNA. The sequence of the RNA molecule is the complement of the sequence of the original DNA template strand. In the case of the mitochondrial DNA of a horse, the complementary RNA sequence is 5'-AAUCUGCUUGGCCUAAAU-3'.
Transcription is a fundamental process for gene expression. Through this process, the information contained in the DNA molecule is made available for the production of proteins and for other cellular functions.

which of the following occurs when an enzyme binds a non-competitive inhibitor? group of answer choices the kd will increase but vmax will not change the vmax will decrease but kd will not change kd will increase and vmax will decrease there is not enough information
When an enzyme binds a non-competitive inhibitor, the vmax will decrease but the kd will not change.
An enzyme is a protein that acts as a biological catalyst by increasing the rate of chemical reactions in living organisms. The substrate is the molecule that an enzyme catalyzes, while the active site is the region of the enzyme where the substrate binds.
An enzyme inhibitor is a chemical or molecule that inhibits the action of an enzyme. Non-competitive inhibitors can bind to the enzyme either at the active site or at an allosteric site. The activity of the enzyme is decreased by non-competitive inhibitors that bind to allosteric sites.
As a result, the Vmax (maximum velocity of the reaction) decreases, but the Kd (dissociation constant) does not change. This implies that the affinity of the enzyme for the substrate does not alter.
The Michaelis-Menten equation can be used to study the effect of enzyme inhibitors on enzyme-catalyzed reactions.
Therefore, when an enzyme binds a non-competitive inhibitor, the Vmax will decrease, but the Kd will not change.

Explain how resting potential is maintained along an axon, the events that lead to an action potential, and the events of an action potential itself
The depolarizing current causes a burst of electrical activity called an action potential. This indicates that due to an action (stimulus), the resting potential becomes 0 mV.
The sodium/potassium pump uses ATP to transport 3 sodium ions out of the cell and 2 potassium ions into the cell, thus maintaining the resting membrane potential at the axon. This keeps the apparent negative charge of the neuron in place. The sodium-potassium pump sequentially removes three sodium ions from the cell for every two potassium ions introduced.
As such, it retains the significant gradient of potassium ions across the membrane that underlies the resting membrane potential.

What is codon?Sequence of three consecutive nucleotides in DNA or RNA molecule that codes for specific amino acid is called as codon.
Assuming the original DNA code is the template strand, the replicated DNA code will be:
TAA CGTGAT
To determine the mRNA codons, we need to transcribe DNA code into mRNA by replacing T with U: UAA CGUGAU
mRNA codons are therefore: UAA CGU GAU
The anticodon for UAA is AUU, which pairs with the codon UAA via complementary base pairing. The anticodon for CGU is GCA, which pairs with the codon CGU via complementary base pairing. The anticodon for GAU is CUA, which pairs with the codon GAU via complementary base pairing.
Therefore, tRNA anticodons are: AUU CGC CUA
To determine the amino acid sequence, we need to use genetic code to translate the mRNA codons into their corresponding amino acids.
UAA = Stop codon
CGU = Arginine (Arg)
GAU = Aspartic acid (Asp)
Therefore, amino acid sequence is: Stop - Arg - Asp
