TRNA (translate rna) and mRNA(messenger rna).
JulsSmile [24]3 years ago

Answer:

Transfer RNA (tRNA) and messenger RNA (mRNA)

Explanation:

Translation is the second process of gene expression. It is where the synthesis of protein occurs using the information in the nucleotide sequence of mRNA. Translation of mRNA cannot occur without ribosome and tRNA.

Translation occurs inside a complex containing ribosomal RNA and other enzymes, called Ribosome. The Ribosome organize translation and catalyze the reaction that joins amino acids to make proteins.

A transfer RNA (tRNA) is a special type of RNA molecule. It matches an mRNA with the amino acids it codes for.

N.B: The mRNA formed during transcription is in a group of three nucleotides called CODON.

A molecular bridge or link is formed between mRNA and tRNA. Each tRNA molecule contains a set of three nucleotides called ANTICODON. The anticodon of a given tRNA can bind to one or a few specific mRNA codons and read it. The tRNA reads the mRNA codon by using its own ANTICODON. The reading is done by matching the base pairs through hydrogen bonding following the base pairing rule. This allows the tRNA to carry an amino acid to the ribosome, specifically, the one encoded by the codons that the tRNA binds, in order to add to the protein chain being formed. Each codon is read by various tRNA's until the appropriate match of the anticodon and the codon occurs, after which they bind.

For example, the tRNA anticodon (AAG) reads the codon (UUC). The UUC codon codes for Phenylalanine, hence, the tRNA binds the amino acid, Phenylalanine, via its amino acid attachment site and carries it to the growing pepetide chain.

Note that, the tRNA is folded into an L-shape in which one of the L shape has the anticodon and the other has the attachment site for amino acid.

1. Explain why neither cyclins not kinases alone can cause a cell to progress along in the cell cycle.
Degger [83]
1. Explain why neither cyclins nor kinases alone can cause a cell to progress through the cell cycle.

As cyclin accumulates, it activates their kinases that turn on the pathway to mitotic spindle formation, and so on.

2. How do controls of the cell cycle protect multi-cellular organisms from accumulating large numbers of damaged or defective cells?

The checkpoint control is responsible for multi-cellular organisms for not accumulating large numbers of damaged or defective cells. Checkpoint controls consist of proteins that detect mistakes and damage and quickly halt the cell cycle until repairs are made. When this occurs, the cell is said to be in cell-cycle <span>arrest.

Cancer is cause by mutations in the genes that encode these proteins can lead to uncontrolled growth. Cancer is when there is uncontrolled cell growth and reproduction. Metastasis is caused by tumors when they grow and interfere with the surrounding tissue or cells and break off and spread around the body. Cancerous tumors cause metastasis, and tumors are caused by mutations in genes that lead to uncontrolled growth.
4. What are the functions of tumor-suppressor genes and protoncogenes in noncancerous cells?
The genes that encode the checkpoint proteins are called tumor suppressors because they suppress the development of cells into tumors. If mutations inactivate these genes, the cell-cycle break is removed with or without a signal from the outside. Proto-oncogene’s are involved in promoting cell division, mutations can cause them to become oncogenes, or cancer genes which stimulate cells to leave G0 and divide whether or not it is a signal.

In a short essay (100-150 words), describe Darwin's view of how natural selection resulted in
Zinaida [17]

Answer:

Charles Darwin was the man who came with the theory of natural selection. He witnessed finches within the Galapagos Islands and made notes on the similarities and differences of the finches across the group of islands. Each of the islands comprises finches, which were identical, however distinct in different ways.  

Darwin found that the finches appeared to vary on the basis of the food sources available on each of the islands. If the prime food were seeds, the finches seemed to possess thicker beaks in order to break the seeds so that they can consume them.  

On the other hand, if the prime food sources were insects, then the finches seemed to exhibit smaller and pointer beaks so that they could hold the insects readily. In this way, there is unity in diversity. All of these birds are finches and exhibited a common ancestor from which they have originated into the distinct species as mentioned.  

Their variations lie in the habitats, in which they now inhabit. They had to amend with their environments in order to thrive, thus, offering diversity to unity.

Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 0 percent solute solution
Vladimir [108]

Answer and explanation:

If a human blood cell with a 0.9% solute concentration were to be put into a container of 0% solute solution, the cell would get BIGGER.

<u>The cell contains a </u><u>more concentrated solution</u><u> than the solution in the container</u>. The difference in concentration would produce an <em>osmotic gradient</em> that would cause water from the container to get inside the cell to even the concentrations - this is going to make the cell much bigger because the entering water would bloat the cell.

In this example, the solution in the container is hypotonic in relation to the cell, while the solution inside the cell is hypertonic in relation to the solution in the container. This is why the water will be moving from outside of the cell to the inside of the cell.
