Use your knowledge of Protein Synthesis, and the provided chart, to identify the
correct Amino Acid sequence from the mRNA strand: AGUUGGUCUGUA
A: serine, tryptophan, serine, valine
B: aspartic acid, valine, leucine, asparagine
C: leucine, histinde, glutamic acid, leucine
D: serine, threonine, arginine, aspartic acid
Answer:
A: serine, tryptophan, serine, valine
Explanation:
Hi there!
Protein Synthesis is the process where proteins are created from DNA.
We are given the mRNA strand AGUUGGUCUGUA, as well as a provided chart
The mRNA strand is created out of nucleotides (each of the letters is one nucleotide in the code), which will code for a specific chain of amino acids, creating a protein.
Each amino acid is made up of 3 nucleotides. This sequence of 3 nucleotides is called a codon.
So we can break up the code into groups of 3, to make identifying the codons easier.
AGU UGG UCU GUA
Now we need to figure out which amino acid each codon codes for. Thankfully, we were given a chart that can help us with that.
The chart is read where the first base is on the left, and is vertical. The second base is in the center, yet is horizontal. The third base is on the right, and is also vertical.
Let's start with the first codon, which is AGU
The first base is A. The second base is G, and the third base is U. So the first amino acid is serine (ser)
The second codon is UGG.
The first base is U, the second base is G, and the third base is G. So the second amino acid is tryptophan (trp)
The third codon is UCU
The first base is U, the second base is C, and the third base is U. So the third amino acid is serine (ser)
The fourth codon is GUA
The first base is G, the second base is U, and the third base is A. So the fourth amino acid is valine (val).
That means the amino acid sequence from the mRNA code is: serine, tryptophan, serine, valine. The answer is A

Explanation:
The plant has the largest vacuole than animal cells. The cytoplasm is mostly composed of water, salts, and proteins. It is one out of 2 types of endoplasmic reticulum, characterized by the appearance of the ribosomes that give it a grainy appearance. The cell membrane is made of millions of smaller molecules that create a flexible and permeable container.

Okazaki fragments are best described as:
A. short segments of DNA formed on the leading strand.
B. cause by the DNA Helicase building in the 3 to 5' direction.
C. short segments of replicated DNA formed on the lagging strand.
O
D. caused by the single strand binding proteins moving in away from the replication fork.
DNA replication occurs only in 5'-3'. Option C. Okazaki fragments are best described as short segments of replicated DNA formed on the lagging strand.
What is an Okazaki fragment?During DNA replication, the molecule unwinds and the two strands get separated.
Different enzymes and proteins are involved in the replication fork formation, such as helicase (enzyme needed to break hydrogen bonds and separate the two original strands) and topoisomerase (enzyme that releases tension).
DNA polymerase makes the new nucleotides enter the fork and pairs them with the corresponding nucleotide of the original strand. Adenine pairs thymine, and cytosine pairs guanine.
Since DNA strands are antiparallel and replication occurs only in 5'-3' direction, one of the strands will replicate continuously, while the other strain will be replicated by short fragments known as Okazaki fragments.
Okazaki fragments are only formed on the lagging strand.
According to this framework, the correct option is C. short segments of replicated DNA formed on the lagging strand.

Which element has four valence electrons?
(1 point)
O beryllium (Be)
O potassium (K)
O sulfur (S)
O silicon (Si)
Answer:
O silicon (Si)
Explanation:
-Valence electrons are electrons of the outermost shell which can participate in chemical bonding. ... -As in silicon, four electrons are present in the outermost shell, so silicon has Four valence electrons.
Among the options given in the question, the element that has four valence electrons is known as Silicon. Thus, the correct option for this question is D.
What are Valence electrons?Valence electrons may be defined as the number of electrons that are present in the outermost shell of an element. These electrons actively take part in chemical bonding due to the sharing and pairing of electrons.
The atomic number of beryllium is 4, it has valance electrons of two. Potassium has an atomic number of 19, it has a valence electron of one. Sulfur possesses an atomic number of 16, it has valence electrons of six. While Silicon has an atomic number of 14, its electronic configuration is 2, 8, and 4. So, it has valence electrons of four.
Therefore, the element that has four valence electrons is known as Silicon. Thus, the correct option for this question is D.
