Answer:

Fatty acids are long chain carboxylic acids, they contain the carboxyl, COOH, functional group. The general formula for a fatty acid is R-COOH where R represents a long hydrocarbon chain. If the hydrocarbon chain, R, contains only single bonds between the carbon atoms, the fatty acid is said to be saturated.

A part of an mRNA molecule with the following sequence is being read by a ribosome: 5'-CCG-ACG-3' (mRNA). The charged transfer R

Protein synthesis involves transcription and translation. During transcription, mRNA complements the DNI template strand. During translation, mRNA codons specify the amino acids that must be added to the growing polypeptide by tRNA.

-----------------------

Before answering all these questions, let us review some framework.

Nitrogenated bases that conform nucleic acids correspond to purines and pyrimidines.

Adenine and guanine ⇒ purines,
Thymine, Uracile, and Citocine ⇒ Pyrimidines.

⇒ In the DNA molecule, Adenine always forms pairs with Timine , while Guanine forms pairs with Cytosine.

⇒ In RNA molecule, Timine is replaced by Uracil. So Adenine forms pairs with Uracil, and Guanine forms pairs with Cytosine.

Transcription occurs in the nucleus. The template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule that grows in direction 5´→ 3´.

Translation occurs in the cytoplasm, where a ribosome reads mRNA in the 5´ to 3´ direction. According to the codons being readen, tRNA transfers the correct amino acids to build the polypeptide chain.

Codons are short sequences of three nucleotides that carry the genetic information for the aminoacids´ assembly.

mRNA has start and end codons. Between them, there are codons that code for the amino acids to be added to the chain. The start is the signal of the synthesis initiation. When the ribosome reaches the end codon, protein synthesis is over.

There exists a total of 64 codons.

One of them is the start codon → AUG → Metionine
61 codify amino acids, and
the remaining three are stopping points → UAA, UAG, UGA.

-----------------------

Now, let us answer the questions.

mRNA ⇒ 5'-CCG-ACG-3'

tRNA ⇒ 3'-GGC-UGC-5' ⇒ tRNA Anticodon
Protein ⇒ Glycine-Cysteine ⇒ dipeptides

GGC codes for Glycine, while UGC codes for Cysteine

tRNA ⇒ AUG ACA ⇒ Anticodons
mRNA ⇒ UAC UGU ⇒ Codons

DNI strand ⇒ CAG
mRNA strand ⇒ GUC

Protein ⇒ Val - His - Thr
DNI Strand ⇒ CAT - GTA - TGG

tRNA ⇒ RNA that functions to use coded instructions to assemble amino acids

RNA ⇒ Transfers genetic information from the nucleus to the cytoplasm ⇒ After transcription and before translation

How can tiny bacteria and a large giraffe both be described by the cell theory?

Mazyrski [523]

Answer:

The cell hypothesis by Schleiden and Schwann gave the proof and proposed that all the living being on earth are comprised of cells and cell is the basic or fundamental unit and practical unit of life. Moreover, the cell emerges from the previous cells was added by the Virchow to the cell hypothesis.

The cell hypothesis shows that whether a living being is tiny or a plainly visible giraffe as examined in the given question is made up of the major unit of life called "cell". The unicellular bacteria though the giraffe is multicellular.

Which of the following is a process that occurs only in the biosphere? condensation infiltration precipitation transpiration

Rainbow [258]

Answer:

Transpiration

Explanation:

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism.

Hope it helps!!!

What is the purpose of mitosis? What would happen if cells did not undergo mitosis?

marissa [1.9K]

Mitosis is the process of cell reproduction. A cell cannot live forever so they either divide into two new cells through mitosis or die. The main purpose of mitosis is to replicate cells. If cells would not undergo mitosis, there would be no cell divisions, and the organism could not develop or increase in size. For example, after fertilization, after a zygote is formed, it undergoes mitotic divisions and as a resulting, embryo will be developed. If there were no mitosis, the embryo would not be formed, so the organism could not be developed.
