The complimentary base pairs for ACT are
Chargaff's rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G). A purine always pairs with a pyrimidine and vice versa. However, A doesn't pair with C, despite that being a purine and a pyrimidine.
Explanation:Complementary base pairs refer to the nitrogenous bases adenine, thymine, cytosine, and guanine. in a double strand of DNA, adenine will always pair with its complement thymine and cytosine will always pair with its complement guanine. This means that the two strands are complementary to each other. For example, a strand of DNA with a nucleotide sequence of AGTCATGA will have a complementary strand with the sequence TCAGTACT.

In a cell undergoing meiosis, if synaptonemal complexes form or are still present, what process or processes have occurred?.
The synaptonemal complex , which mediates the pairing of homologous chromosomes,the critical significance in chromosome synapsis and genetic recombination, its exact molecular activity is still unknown.
When during meiosis do Synaptonemal complexes form or are still present?
Nuclear division occurs twice during meiosis, producing four nuclei and typically four daughter cells, each of which has half as many chromosomes as the parent cell.The first divides homologs, whereas the second divides chromatids into individual chromosomes, much like mitosis. When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place.Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father, line up.The same genes may be present on the two chromosomes in different versions. During meiotic prophase, the synaptonemal complex (SC), a highly organized proteinaceous structure, forms at the junction of aligned homologous chromosomes.It has been shown that the SC has a role in both the stabilization of homolog pairing and the promotion of interhomolog crossovers (COs). By means of homologous recombination, chromosomal fragments are exchanged (crossover creation).When a cell exits pachytene and during the diplotene stage, the SC disassembles and homologous chromosomal arms separate. Meiosis increases genetic diversityEach gamete has a unique DNA set because of recombination and independent assortment during meiosis.The resultant zygote has a special set of genes as a result. The single option that does not take place during mitosis is crossing across.Crossing over includes the exchange of genetic material between homologous chromosomes and takes place during prophase I of meiosis.Tetrad formation is necessary for this, which does not take place during mitosis.

The difference between the macromolecules consumed by Americans and the elemental composition of human body is that these macromolecules provides energy, support and help speed up reactions in them while the elemental composition of human body are used to build proteins, carbohydrates and nucleic acids to perform their respective functions.
How macromolecules provide support.Macromolecules helps to give structural support to the body system through the proteins in our diet by consumption. They do this by acting either as hormones or carriers to aid metabolic activities.
From the task above, we can see that about 78% of carbon in American bodies are from the consumption of corn. Whereas in France, the percentage of carbon which is found in their body system is not upto 78% but 15%.
It has also been proven practically that the food substances consumed by Americans contains majorly of carbohydrates. Lipids and proteins is in low amounts or quantities, roughly almost the same amount.
Macromolecules such as glucose combines with oxygen to produce water, carbon dioxide and ATP in the reaction below:
C6H12O₂ + 6O₂ + 36 ADP+ 36 Pi → 6CO₂ + 6H₂O + ATP
The pi above means the phosphate group and ADP means adenosine diphosphate.

photosynthesis and cellular respiration both use electron transport chains. what is the source of electrons for photosynthesis and where do the electrons go at the end of aerobic cellular respiration?
Water serves as an electron source in the electron transport process of photosynthesis. The electron is extracted from water by using solar energy.
What is the electron transport chain's source of energy?
The electron transport chain uses the energy released by oxygen and reduced compound reactions such as cytochrome c and (indirectly) NADH and FADH2 to pump protons into the intermembranous space, producing the electrochemical gradient over the inner mitochondrial membrane.
In photosynthesis, water is split to produce electrons in the presence of sunlight, a process known as the photolysis of water. The electrons are finally transferred to NADP+ by the chloroplast electron transport chain, where they are reduced to NADPH.
Therefore, In aerobic respiration, electrons from NADH and FADH2 are transferred to oxygen by the mitochondrial electron transport chain to reduce oxygen in the water.

The process of photosynthesis is commonly written as:
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂.
The light-dependent and light-independent reactions are the two steps. The light reactions of photosynthesis take place in the thylakoid membrane, whereas the dark reactions are located in the chloroplast stroma.
In higher plants, algae, and cyanobacteria, a membrane protein supercomplex called photosystem II (PSII) carries out the first step of photosynthesis. To accelerate a transmembrane charge separation, it absorbs sunlight.
To begin photosynthesis, a photon interacts with photosystem II's antenna pigments. The hydrogen ions are pumped into the interior of the thylakoid by the electron transport chain after the energy passes through the reaction center, which contains chlorophyll a. A significant ion concentration is created by this action.
During photosynthesis, it is the conversion of ADP to ATP utilizing solar energy. In the mitochondria of a cell, the process of cellular respiration also results in the formation of ATP.
Chloroplasts include ferredoxin (Fd), an enzyme that facilitates electron transport and has an iron-sulfur cluster. When being oxidized or reduced, its iron atoms accept or release electrons, which is how it participates in the photosynthesis process.
Hydrogen ions, oxygen ions, and electrons are separated from water. Within the thylakoid lumen, oxygen and protons created by the splitting of water are discharged.
Cyclic photophosphorylation, is described as the production of ATP related to electron transport that is only activated by Photosystem I (700 nm). The particular Photosystem II inhibitors CMU, DCMU, and orthophenanthroline have no impact on this process.
The enzyme that produces ATP via chemiosmosis is called ATP synthase. It permits protons to cross the membrane and generates ATP by phosphorylating adenosine diphosphate (ADP) with the free energy difference. In addition to mitochondria and chloroplasts, most bacteria and archaea also produce ATP by chemiosmosis.

Photosynthesis is the atp-producing process which uses light energy.
Photophosphorylation is the term describes atp production resulting from the capture of light energy by chlorophyll.
Photosynthesis is the process by which light energy is converted into chemical energy in the form of sugars. Using light energy, oxygen is produced as a byproduct while carbon dioxide and water are converted into glucose (or other sugars).
ADP is converted to ATP by the process of photophosphorylation using light energy from photosynthesis. Energy-dense ATP molecules are produced when the ADP molecule is lighted by transferring the phosphate group into it.
Two types of photophosphorylation exists:
1. Circular Photophosphorylation - For instantaneous energy for the cells, the electrons are moved from ADP to ATP throughout this procedure. This procedure typically uses Photosystem I and chlorophyll P700 and occurs in the thylakoid membrane. The cyclic movement of electrons during the synthesis of ATP molecules is known as cyclic photophosphorylation.
2. Non- cyclic Photophosphorylation - Utilizing the energy from excited electrons produced by Photosystem II, the process of photophosphorylation produces ATP molecules. Because the primary acceptor transports the electrons released by P700 before they are finally transferred to NADP, this process is not cyclic.
