The DNA template strand of a gene near a promoter reads 5'-TAGAACGCCTCGAAATTTCATACT-3' The amino terminus of the encoded protein whose translation starts in this region is:
Answer:
The N-terminal aminoacid is Metionin.
Explanation:
Before answering the question, let us remember the meaning of the term amino terminus. Terminus refers to the extremes of the polypeptide. During translation, rRNA and tRNA read mRNA in 5´ to 3´ direction. The first extreme to be translated carries the amino-terminal group, while the other extreme carries the carboxy-terminus group.
Conventionally, proteins are written from left to right, beginning by the N-terminal extreme carrying the free amine group, and ending by the C-terminal extreme carrying the carboxyl free group. However, we need to know that the free amine group actually places at the end of a protein.
Transcription:
Transcription occurs in the nucleus where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.
template DNI strand ⇒ 5'-TAGAACGCCTCGAAATTTCATACT-3'
mRNA ⇒ 3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´
Translation:
Translation occurs in the cytoplasm. rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.
Protein synthesis initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA.
The first portion of mRNA is not read nor translated. This is the untranslated region (UTR), placed before the strat codon.
mRNA ⇒ 3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´
Remember that transcription occurs from 5´ to 3´ extremes, so we need to read the codons in this direction too, beginning on the 5´ extreme.
First, we need to find the initiation codon: AUG coding for Metionin.
mRNA ⇒ 3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´
Met
mRNA ⇒ 3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´
Lys Met
mRNA ⇒ 3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´
Phe Lys Met
mRNA ⇒ 3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´
Arg Phe Lys Met
mRNA ⇒ 3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´
Gly Arg Phe Lys Met
mRNA ⇒ 3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´
Val Gly Arg Phe Lys Met
mRNA ⇒ 3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´
Leu Val Gly Arg Phe Lys Met
The N-terminal aminoacid is then Metionin.

Answer:
Pollen grains are also adapted for insect pollination. Some pollen grains are hairy or spiky, and others are sticky, so they attach to the insect. The anthers dangle in the breeze, and the pollen is blown away. The pollen grains are very small and light so they are easily carried on the wind.

centimeters?
(3)
A) 2.75 x 10-3 cm3
C) 275 x 10-3 cm3
E) 27.5 x 103 cm3
B)
2.75 cm
D)
2.75 x 103 cm
Answer:
2.75 x 10³ cm³
Explanation:
Volume can be measured in both liters (L) and cubic centimeters (cm³), however,
1 liter = 1000cm³
According to this question, a partly full paint has 2.75 liters of paint left in it.
Since 1 liter = 1000cm³
2.75 liters = 2.75 × 1000
2.75 × 10³ cm³ is left.

b) The antigen-presenting cell displays the antigen to the T cells.
c) The T cells initiate the immune response if the antigens are viral proteins or abnormal antigens.
a) Infected or malignant cells are then destroyed before they can do further harm to the body.
Explanation:
The antigen-presenting cells (e.g., dendritic cells, macrophages) are cells of the immune system that mediate cellular immune responses by processing and presenting antigens (i.e., peptides components of pathogens) to T lymphocytes. The antigen-presenting cells travel through lymphatic vessels from the site of infection to the lymph nodes where they present antigens to naive T cells, i.e., T cells that have matured but have not yet encountered their corresponding antigens. This presentation facilitates the clonal expansion of T cells that are specific for the antigen which acquire effector functions in order to destroy infected cells. This process is known as immune clearance and is associated with the apoptosis of antigen-specific T cells.

How much stronger is a magnitude 8 earthquake than a magnitude 5 earthquake?
A. 1000
B. 30
C. 3
D. 10
Answer:
A. 1000
Explanation:
The Richter scale is a scale of numbers used to measure the magnitude of an earthquake, which is based on the size of its seismic waves. This scale indicates a number to quantify the total seismic energy released by an earthquake. The Richter magnitude scale is a base-10 logarithmic scale, thereby a difference of one (1) point in the scale of magnitude corresponds to a 10-fold increase in amplitude. For example, based on the Richter scale, a magnitude-8 earthquake is 100 times greater than a magnitude-6 and 1000 times greater in amplitude than a magnitude-5.

Imagine the CCA added to the 3' end of the tRNA consisted of DNA nucleotides. It (WOULD/WOULD NOT) be possible to connect an amino acid to this tRNA. Explain.
Answer:
The correct answer is - it would because both DNA and RNA have 3' OH.
Explanation:
Ammino acid will connect to the tRNA due to the fact that the process of aminoacylation of tRNA when DNA nucleotide is used will perform or act same the mechanism of Class II aminoacyl tRNA synthetase as both DNA and tRNA have 3'OH. This will get the help of 3'OH in the CCA to bond with charged amino acid.
Thus, the correct answer would be - it would because both DNA and RNA have 3' OH.
What is a way to prevent eutrophication?
Answer:
Agricultural fertilizers are one of the main human causes of eutrophication. Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. The use, or overuse, of fertilizers can cause these nutrients to runoff of the farmer's field and enter waterways. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.
The following is a list of methods that can be used to control eutrophication:
planting vegetation along streambeds to slow erosion and absorb nutrients.
controlling application amount and timing of fertilizer.
controlling runoff from feedlots.
The best, easiest, and most efficient way to prevent eutrophication is by preventing excess nutrients from reaching water bodies. This can be done in a number of ways, the simplest of which is just being aware of the chemicals and fertilizers that we are using.
