If a tRNA molecule has an anticodon which reads AGGCCG, what was the codon on the mRNA molecule?
TCCGGA
UCCGGC
UCCGGU
CTTAAG
The codon is the sequence of nucleotides that carry genetic information that determines which amino acid should be added to the building protein. Nucleotides in this sequence pair with nucleotides from the tRNA anticodon. In the exposed example, the correct codon pairing the given anticodon is is UCCGGC.
Before expplanation, let us review some theoretical frame to answer the question.
During protein synthesis, the ribosome reads mRNA in the 5´ to 3´ direction, while tRNA adds the correct amino acids to build the polypeptide, according to the codons readen in the mRNA chain. A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly. Each of the codons represents one of the 20 amino acids used to build the protein. Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid. tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.
Once the new amino acid joins the growing protein, the binding between the amino acid and the tRNA breaks, releasing the molecule, which is now available to join another amino acid and repeat the cycle.
• Anticodon: Sequence of bases that pairs with the mRNA codon.
• Amino Acid: the amino acid that is codified by the mRNA codon.
Remeber that:
Adenine forms pairs with Uracyl ⇒ A↔UGuanine pairs with Cytosine ⇒ C↔GIn the exposed example, the tRNA anticodon is AGGCCG, so we need to find its complement.
We know that Adenine pairs Uracyl, Guanine pairs Cytosine, and Cytosine pairs Guanine. So,
Anticodon → AGGCCG
Codon → UCCGGC

You farm kelp and sell the kelp for food and as fertilizer. The wastes from the kelp can be used in an integrated aquaculture system in which kelp farming can be coupled with farming of fish or abalone. Make an argument that you are using a sustainable system of growing a renewable resource, and explain why it is beneficial (and more sustainable) to couple algae farming with fish farming than simply to farm fish independently.
Answer:
A sustainable system refers to producing less or probably non-existent debris that are caused by the production of a particular material (i.e. produce, energy). This is a sustainable form of production of coupling algae growth and fish farming because you no longer need the supply of fish feed from other sources that are made artificially but rather, you are using the available algae growth that you are culturing. Farm fishing alone is non-renewable because this produces much waste that can directly harm the environment.
An integrated aquaculture system of fish farming with kelp farming is a sustainable system as both system exchange resources and thus reduce wastage of resources.
What is an integrated aquaculture system?An integrated aquaculture system is an aquaculture system which combines several forms of aquaculture together.
For example, kelp farming is a form of aquaculture which can be integrated with another form of aquaculture such as fish farming.
Integrating fish farming with kelp farming is a sustainable system as both system provides what the other needs.
The kelps serve as food to fish while fish waste serve as manure for kelps.
Therefore, integrating fish farming and kelp farming is a form of a sustainable system.

(2 points) O Uracil, adenine, adenine, cytosine, guanine, uracil Adenine, thymine, thymine, guanine, cytosine, adenine Thymine, adenine, adenine, cytosine, guanine, thymine O Guanine, cytosine, cytosine, adenine, thymine, guanine
Adenine, thymine, thymine, cytosine, guanine, and adenine is the correct order in which nucleotides add on single strand DNA.
What is DNA replication?The process of DNA replication is crucial for cells to divide and create an exact copy of their DNA. Enzymes like helicase play a vital role in unwinding and separating the two strands of the double helix, creating a replication fork that serves as the starting point for this process. As DNA polymerase adds nucleotides to the new strand using the existing strand as a template, it follows specific rules of complementary base pairing: adenine (A) pairs with thymine (T), while cytosine (C) pairs with guanine (G).
What will be order of nucleotides to add on single strand of DNA?During DNA replication, the order in which free nucleotides will add on to a single strand of DNA with the sequence ATTGCA is crucial. The correct sequence of nucleotides that will bind to this template strand is adenine (A), thymine (T), thymine (T), cytosine (C), guanine (G) and adenine (A). This follows the complementary base pairing rules where A pairs with T and C pairs with G. By following these rules, the newly synthesized strand will have a correct sequence of ATTTGC, ensuring accurate replication.

During diffusion, molecules move from areas of blank concentration to areas of blank concentration. Diffusion does not require blank to move molecules.
Answer:
high; low; energy.
Explanation:
Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.
This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.
During diffusion, molecules move from areas of high concentration to areas of low concentration. Also, diffusion does not require energy to move molecules.
In conclusion, increasing the surface area of a gas increases its collision rate and it's considered to be an evolutionary strategy that maximizes the diffusion of gas molecules because it catalyzes the rate of a gaseous reaction.
Which equation represents fertilization?
haploid + diploid = diploid
diploid + haploid = haploid
haploid + haploid = diploid
diploid + diploid = diploid
Answer:
the answer is (C) haploid + haploid = diploid
Explanation:
edge 2021
Haploid+ Haploid = Diploid represents fertilization. So, the correct option is (C).
What is Fertilization?
Fertilization is defined as the process in which two gametes where one male and one female first form a zygote and then lead to the development of an embryo.
These germ cells are cells that give rise to gametes – either egg cells that are female gametes or sperm cells that are male gametes.
These germ cells are the only cells that can undergo both mitosis and meiosis. These are the diploid cells present in the gonads. After meiosis, haploid gametes are produced. In fertilization two haploid gametes fuse (n+n) and form a diploid zygote (2n)
Thu, Haploid+ Haploid = Diploid represents fertilization. So, the correct option is (C).

What type of unconformity did Hutton see at Siccar Point and how was this uniformity formed?
Answer:
Hutton's Unconformity
At Siccar Point, during the lower Silurian Llandovery epoch around 435 million years ago, thin beds of fine-grained mudstone were laid down gradually deep in the Iapetus Ocean, alternating with thicker layers of hard greywacke formed when torrents swept unsorted sandstone down the continental slope. Siccar Point is a rocky promontory in the county of Berwickshire on the east coast of Scotland. It is famous in the history of geology for Hutton's Unconformity found in 1788, which James Hutton regarded as conclusive proof of his uniformitarian theory of geological development.

B. A nondisjunction in both gametes of the parents
C. A nondisjunction in one of the first gamete cells of the individual
D. A nondisjunction mutation in body cells of both parents
Answer:
if An individual has an extra chromosome in every one of its cells, the mutation that must have occurred is A non-disjunction mutation in the gamete of one of the parents
If an individual has trisomy resulting in Down syndrome and has an extra chromosome in each cell, the mutation that must have occurred is A. A nondisjunction mutation in the gamete of one of the parents.
Down syndrome simply means a genetic disorder that is caused when there's an abnormal cell division that then leads to extra genetic material.
The effect of Down syndrome is the fact that it leads to an intellectual disability, developmental delays, and a distinct facial appearance.
The mutation that has occurred with someone that has a Down syndrome is the nondisjunction mutation in the gamete of one of the parents.
