If the gene sequence of DNA is A T T C G A C T C G what will the complementary mRNA sequence be that is made during transcription?
Answer:
U A A G C U G A G C
Explanation:
The complementary bases in RNA are the same as DNA with G-C (guanine to cytosine).
But, they are different in that RNA has A-U (adenine to uracil) instead of A-T (adenine to thymine).
Using these RNA base pairs of G-C and A-U, create the complementary mRNA sequence:
A T T C G A C T C G
Translate:
U A A G C U G A G C
So, the complementary mRNA sequence will be U A A G C U G A G C

These are polar side chains of amino acids that tend to associate to form hydrophobic clusters usually close to the protein surface. These are polar side chains of amino acids that tend to destroy hydrophobic clusters close to the protein surface.
Answer:
Nonpolar side chains of amino acids tend to associate to form hydrophobic clusters usually away from the protein surface.
Explanation:
Hydrophobic interactions are defined as the relationship between the low water soluble molecules named hydrophobes and water. They contains a long chain of carbon atoms and are usually considered as a nonpolar molecules.
They occur when the non polar amino acids are associated to produce the hydrophobic clusters that are usually away from the surface of the protein.
How do I make a Punnet Square without knowing if traits are Dominant or Recessive? I cannot refer to the parents of the current generation, so I have to rely on that generation to create a theoretical next generation.
If you are referring to a previous generation, that would probably mean that the traits they have are the dominant ones
Explanation:
if you know all the traits possible, then the ones the parents have of a previous generation are most likely the dominant ones, from there, you can hopefully figure out another generation. could you attach a picture if this didn't help? thanks

(ii) Fish use their gills as a gas exchange surface.
Suggest three ways in which fish gills are adapted for efficient gas exchange.
(3)
1

Since the reason of the large surface area of the gills, gas exchange in fish is very efficient. the blood capillaries' large surface area in each gill filament The outer layer of the gill filaments as well as the capillary walls are only one cell thick due to the short distance required for diffusion.
What are gills?A gill is a respiratory organ found in many aquatic organisms that allows them to extract dissolved oxygen from water and expel carbon dioxide.
Some species' gills, such as hermit crabs, have adapted to allow them to breathe on land as long as they are kept moist.
Water runs over the gills as the fish opens its mouth, and blood in the capillaries picks up oxygen dissolved in the water. The blood then circulates through the fish's body to deliver oxygen, just as it does in humans.
Fish have gills, which allow them to "breathe" oxygen from the water. Water enters the mouth, travels through the gills, and exits the body via a special opening.
As the water passes over them, the gills absorb oxygen from it. The body of a fish is stream-lined.
Thus, these are the ways, in which fish gills are adapted for efficient gas exchange.

What cycle of replication is used by the common cold virus?
A: Dormant cycle
B: Replication cycle
C: Lytic cycle
D: Lysogenic cycle
Answer:
C
Explanation:
The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.
The common cold virus is replicated using the lytic cycle, by introducing its genome into the host and using its cellular machinery, hence option c is correct.
How common cold virus replicate?The common cold virus is replicated by using the lytic cycle, in which the virus introduces its genome into the host genome and uses all the replicating machinery of the virus.
The lysogenic cycle is different from the lytic cycle in which the viral genome replicates on its own and does not integrate its genome into the host genome.
After replicating its genome with the host genome, the viral genome is excised from the host genome and assembled into new viral particles for infecting other host cells. The new viral particle lysed the host cell and spread to other cells.
Therefore lytic cycle is used by the common cold virus, hence option c is correct.

9. UGU-UUC-CCU-UAA
UGU-UCC-CUU-AA
Answer:
7. Substitution mutation
8. Substitution mutation
9. Frameshift mutation
Explanation:
A substitution mutation is any kind of mutation that involves replacement of one or more nucleotide base by another in a sequence.
A frameshift mutation, on the other hand, is a mutation that changes the reading frame of the sequence. Two types of mutations cause frameshift viz: insertion and deletion mutation.
In the following sequences, mutation has occured as follows:
7. UGU-CCG-GAA-CGA to UGC-CGG-GAA-CGA - Substitution mutation has occured because nucleotides C and G has replaced C and U in the first and second codons respectively.
8. GAA-CGU-AGC-GGU to GAU-CGU-AGC-GGU- A substitution mutation because nucleotide U has replaced A in the first codon.
9. UGU-UUC-CCU-UAA to UGU-UCC-CUU-AA - A frameshift mutation because nucleotide U has been removed from the second codon, hence, causing a change in the reading frame.

What process facilitates locomotion for the ovum?
Question 6 options:
a. Once the ovum leaves the ruptured follicle it is captured by the uterus and then directed into the Fallopian tube, where it is pushed along towards the oviducts.
b. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
c. Once the ovum leaves the ruptured follicle it is fully matured and propels itself into the Fallopian tube, where it moves along towards the uterus.
d. Once the ovum leaves the ruptured follicle it is captured by the cervix and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
The correct answer is B. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
Explanation
Ovulation is a process that occurs during the menstrual cycle that occurs around day 14 of the cycle. In the ovulation process, the eggs go through different places before reaching the uterus (their final destination). The first step is when the egg leaves the broken follicles. The second step is when it is taken to the fallopian tubes (place where fertilization occurs) through the fimbriae. The third step is when the egg uses the cilia to reach the uterus.
Chemosynthesis _______. Question 11 options: uses energy derived from hydrocarbons and hydrogen sulfide in place of solar energy produces carbohydrates and sugars occurs around hydrothermal vents near the oceanic ridge system Both a and c are correct. All of the above are correct.
Answer:
The answer is all of the above are correct.
Explanation:
Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways. For example, at hydrothermal vents, bacteria oxidize hydrogen sulfide and add carbon dioxide and oxygen to produce sugar, sulfur, and water:
CO2 + 4H2S + O2 ⇒ CH20 + 4S + 3H2O.
Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the seafloor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in seawater). Pure sulfur and sulfur compounds are produced as by-products.

Identify the incorrect statement regarding the fundamental causes of edema. Multiple Choice Capillary reabsorption does not depend on oncotic pressure. A deficiency of albumin (hypoproteinemia) produces edema by reducing the reabsorption of tissue fluid. Kidney failure leads to water retention and hypertension, thus raising capillary blood pressure and filtration rate. Obstruction of lymphatic vessels can interfere with fluid drainage and lead to the accumulation of tissue fluid distal to the obstruction. Since albumin is produced by the liver, liver diseases, such as cirrhosis, tend to lead to hypoproteinemia and edema.
Answer:
Capillary reabsorption does not depend on oncotic pressure
Explanation:
Edema refers to the swelling caused by the fluids trapped in the body's tissues, which swell from injury and/or inflammation. Edema can be associated with the decrease in plasma oncotic pressure, i.e., osmotic pressure exerted by proteins (especially albumin) in the blood vessel's plasma, the increase in hydrostatic pressure, or the increase in the capillary permeability. Moreover, capillary reabsorption refers to the movement of fluid from interstitial space to the capillaries, which is driven by the blood colloidal osmotic pressure. Lymphatic obstruction, i.e., the blockage of the lymph vessels that drain fluids from tissues, may cause edema in the part that is drained by the affected vessels (it is known as lymphedema). Moreover, liver/kidney failure may lead to edema by decreasing albumin and oncotic pressure. When plasma albumin levels drop because of liver diseases, the colloid osmotic pressure also decreases. In consequence, liver diseases, including stage 3 cirrhosis, lead to the development of swelling in the abdomen, thereby leading to edema.
