Can RNA sequence be predicted from a known protein sequence? Different nucleotide sequences can encode the same amino acid sequence because the genetic code is redundant.
How does the RNA sequence influence the final protein product?The mRNA interacts with the ribosome, a specialized complex that "reads" the sequence of mRNA nucleotides. An individual amino acid is typically coded for by each group of three nucleotides known as a codon.
Can mRNA levels predict the levels of protein?According to our findings, the amounts of mRNA and protein expression are generally correlated positively. The mild and diverse associations, however, imply that forecasting protein expression levels using mRNA expression may occasionally be possible but is undoubtedly far from accurate.

A denisty of a bottle weighs 0.25N when empty & 0.75N when filled with water & 0.65N when filled with alcohol. Calculate;. 1) the volume of the bottle 2) the denisty of the alcohol (denisty of water is 1000kg/m & g is 10m
Answer:
[tex]0.05\times 10^{-3}\ \text{m}^3[/tex]
[tex]800\ \text{kg/m}^3[/tex]
Explanation:
[tex]W_b[/tex] = Weight of bottle = 0.25 N
[tex]W_w[/tex] = Weight of water = [tex]0.75-0.25=0.5\ \text{N}[/tex]
g = Acceleration due to gravity = [tex]10\ \text{m/s}^2[/tex]
[tex]\rho_w[/tex] = Density of water = [tex]1000\ \text{kg/m}^3[/tex]
Mass of water
[tex]m_w=\dfrac{W_w}{g}\\\Rightarrow m_w=\dfrac{0.5}{10}\\\Rightarrow m_w=0.05\ \text{kg}[/tex]
Volume is given by
[tex]V_w=\dfrac{m_w}{\rho_w}\\\Rightarrow V_w=\dfrac{0.05}{1000}\\\Rightarrow V_w=0.05\times 10^{-3}\ \text{m}^3[/tex]
Volume of the bottle is [tex]0.05\times 10^{-3}\ \text{m}^3[/tex].
This means that the alcohol will take the same amount of volume.
[tex]W_a[/tex] = Weight of alcohol = [tex]0.65-0.25=0.4\ \text{N}[/tex]
Mass of alcohol
[tex]m_a=\dfrac{0.4}{10}\\\Rightarrow m_a=0.04\ \text{kg}[/tex]
Density is given by
[tex]\rho=\dfrac{m_a}{V_w}\\\Rightarrow \rho=\dfrac{0.04}{0.05\times 10^{-3}}\\\Rightarrow \rho=800\ \text{kg/m}^3[/tex]
Density of alcohol is [tex]800\ \text{kg/m}^3[/tex]
The volume of the bottle is 50 mL and the density of alcohol is 0.8 g/c[tex]m^{3}[/tex]
The weight of empty bottle is 0.25N
the weight of bottle filled with water is 0.75N
therefore, the weight of water in the bottle is 0.75N - 0.25N = 0.50N
we know that weight, w =mg , where m is the mass of substance and g is acceleration due to gravity. Here we will take g= 10 m/[tex]s^{2}[/tex] for simplicity.
⇒ m = w/g = 0.5/10 = 0.05 kg
⇒ mass of water is 50g
now, the density of water ρ(w) = 1g/[tex]cm^{3}[/tex] = 1g/mL
relation between mass, density and volume is:
V = m/ρ = 50/1 = 50mL
Hence the volume of the bottle is 50mL.
Now it is given that the weight of bottle filled with alcohol is 0.65N
⇒ weight of alcohol = 0.40N
⇒ mass of alcohol = 0.40/g = 0.40/10 = 0.040kg = 40g
The volume of the bottle remains the same, so to calculate the density of alcohol we use the above mentioned relation between mass, density, and volume on alcohol.
That is, V = m/ρ
⇒ ρ(al) = m/V = 40/50 g/c[tex]m^{3}[/tex]
ρ(al) = 0.8 g/c[tex]m^{3}[/tex] or 0.8 g/mL

Beginning at the synapse of a neuron, place the events in neuronal signaling in the correct sequence. 1. Ion channels bind the ligand and open. 2. Na is pumped out of the cell, and the membrane potential is restored. 3. Acetylcholinesterase breaks down acetylcholine. 4. Na enters the postsynaptic cell, and the membrane potential changes. 5. Acetylcholine is released into the synapse. 6. Na ion channels close. 4, 5, 1, 2, 6, 3 6, 4, 3, 1, 2, 5 3, 4, 6, 1, 5, 2 1, 2, 3, 4, 5, 6 5, 1, 4, 3, 6, 2
Answer: 5, 1, 4, 3, 6, 2
Explanation:
The synapse is an intercellular approach between neurons or between a neuron and a muscle or glandular effector cell. At the synapse, the transmission of the nerve impulse takes place. This is initiated by a chemical discharge that causes an electrical current in the membrane of the presynaptic cell (sending cell). Then, once this nerve impulse reaches the end of the axon (the connection with the other cell), the neuron secretes a chemical compound called neurotransmitter that is deposited in the cleft or synaptic space (intermediate space between this transmitting neuron and the postsynaptic or receiving neuron). These secreted substances or neurotransmitters (noradrenaline and acetylcholine among others) are responsible for exciting or inhibiting the action of the other cell called postsynaptic cell.
The events are:
Acetylcholine is released into the synapse (5): Acetylcholine is a neurotransmitter that is released at synapses in response to a specific stimulus. The secreted neurotransmitter acts on specialized receptor sites on the postsynaptic cell, which causes changes in the metabolism of the postsynaptic cell, modifying its cellular activity. Ion channels bind the ligand and open (1): The channels control the transmission between neurons because they bind neurotransmitters and open in response to a ligand. So the neurotransmitters diffuse across the cleft and bidn to receptors.Na enters the postsynaptic cell, and the membrane potential changes (4): Sodium channels open and allow an inward diffusion of sodium ions (Na+) from the outside to the inside. This causes the membrane potential to become less negative or more positive or to approach the threshold potential. Next, this triggers an excitatory potential (EPSP) so it causes the postsynaptic membrane to depolarize and fire an action potential. which spreads along the membrane of the post-synaptic neuron. This means an impulse is transmitted.Acetylcholinesterase breaks down acetylcholine (3): Acetylcholinesterase is an enzyme that breaks down the neurotransmitter so it causes the inactivation of acetylcholine into acetic acid and choline. Na ion channels close (6): Na channels open and close according to different signals. The peak voltage causes them to close, and potassium channels open. So sodium ions stay inside the cell while potassium ions move outside of it. When this happens, repolarization (change in membrane potential that retunrs it to a negative value) takes place. Potassium channels remain open after the potential reaches the resting level causing hyperpolarization (the membrane potential becomes more negative) and it alters the ability of certain of ions to enter the cell. At the end, the cell has more K+ ions on the outside.Na is pumped out of the cell, and the membrane potential is restored (2): The sodium-potassium pump moves sodium ions to the outside and potassium ions to the inside.4)

Water leaves the cryosphere and joins the rest of the hydrosphere when it
Answer: receives the thermal energy
Explanation:
The cryosphere can be defined as the land which is covered with the surface of ice in the solid form in the form of sea ice, river ice, snow, ice glaciers, ice sheets, frozen water, and others. When the ice on the land receives the thermal energy from the sun or any other source like radiation then it melts into water and it becomes the part of the water body in the form of the hydrosphere.
A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a ___
Answer: A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a GENE.
Explanation:
CHROMOSOMES are made up of two threads called chromatids joined at a point called the centromere.
In the chemical nature of chromosomes, each is made up of a protein framework which has a long molecule of DNA (deoxyribonucleic acid) coiled round it. A segment of DNA containing the instructions for building a protein which will result in a trait is called a GENE.
The GENES in the cell of a diploid organism contain all the necessary instructions for building up the organism.These instructions are written on a molecular scale.. Most genes contain information to direct the synthesis of specific proteins. Each such protein takes part in the development of a particular character.
A protein is made up of one or more chains of amino acids known as polypeptides. The sequence of bases in a DNA molecule determines the type of amino acid and the sequence in which they are arranged in a polypeptide chain.
A gene therefore is a sequence of triplets of the four bases which specifies the structure of a protein
