Answer:
Valine-Leucine-Proline-Lysine-Histidine
Explanation:
The central dogma of biology is the process by which DNA is used to synthesize RNA and subsequently amino acid sequence (PROTEIN). The processes of transcription and translation is used in gene expression. Transcription is the process whereby the information encoded in a DNA molecule is used to synthesize a mRNA molecule. Transcription is catalyzed by RNA polymerase enzyme, which uses complementary base pairing rule i.e Adenine(A)-Thymine(T), Guanine(G)-Cytosine(C) pairing.
N.B: Thymine is replaced by Uracil in the mRNA
For the above DNA sequence: CAC GAC GGA TTC GTA, the mRNA sequence will be: GUG CUG CCU AAG CAU
Translation is the second process of gene expression which involves the synthesis of an amino acid sequence from an mRNA molecule. The mRNA is read in a group of three nucleotides called CODON. Each codon specifies an amino acid (see attached image for genetic code)
Based on the attached genetic code, an mRNA sequence: GUG CUG CCU AAG CAU will encode an amino acid sequence: Valine(Val) - Leucine (Leu) -Proline (Pro) -Lysine (Lys) - Histidine (His).
GUG specifies Valine amino acid
CUG specifies Leucine amino acid
CCU specifies Proline amino acid
AAG specifies Lysine amino acid
CAU specifies Histidine amino acid
The sister chromatids are then pulled apart by the mitotic spindle which pulls one chromatid to one pole and the other chromatid to the opposite pole.
The chromosomes line up neatly end-to-end along the centre (equator) of the cell.
The centrioles are now at opposite poles of the cell with the mitotic spindle fibres extending from them.
The mitotic spindle fibres attach to each of the sister chromatids.
The DNA in the cell is copied in preparation for cell division, this results in two identical full sets of chromosomes?.
Outside of the nucleus? are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division.
Answer:
Excessive nutrients from fertilizer run off.
Explanation:
Scientists have suspected that phytoplankton blooms might be connected to agricultural run-off. They got some evidence from a recent study by comparing the timing of irrigation along the west coast of Mexico and phytoplankton blooms in Mexico’s Sea of Cortez. During the comparison, they had found a close correlation. Phytoplankton blooms occurred in the Sea of Cortez shortly after the irrigation. This happened because of carried fertilizers after irrigation and other agricultural run-offs into the sea.
The bloom detected in the Gulf of Mexico on December 13 might be similarly linked to agricultural run-off.
Fungi are responsible for what common human ailment athlete's foot infections
Answer: Although humans cannot prevent all cancers, a healthy diet and weight followed by adequate exercise, sleep, and stress reduction all play a part in cancer reduction.
Cancer occurs when cells multiply uncontrollably and are not "cleaned up" by the body. We are dependent on our bodies recognizing and destroying old cells and foreign substances like toxins. When our body's fail to do this, either through stress, poor diet or being sedentary, cancer could result.
Hope this helps.
