Photosynthesis, in the chloroplasts of the cells
Answer: d). UAG
Explanation: During translation, DNA sequence is first of all copied into an mRNA in a process known as transcription. This is the first step in protein synthesis. The mRNA is used as a template in protein synthesis. The genetic information encoded in an mRNA are in form of codons. A Codon is a three nucleotide sequence that codes for a specific amino acid. These codons are recognized by anticodons in a tRNA molecule. An anticodon is a three-base sequence on the tRNA through which tRNA base pair with mRNA.
From the DNA sequence above, 3'TAG will first be transcribed into an mRNA sequence AUC, then the anticodon on the tRNA will be UAG. The mRNA codon-tRNA anticodon base pairing follows the Watson and Crick base pairing in which Adenine pairs with Uracil and Cytosine pairs with Guanine.
ANSWER:
Cytokines, Chemokines, Leukocytes, Neutrophils, Macrophages, and Dendritic cells are all involved
EXPLANATION:
On the incidence of Streptococcus, the immune system activates a complex response that relies basically on the instatement and activation of macrophages, neutrophils, and dendritic cells.
These activities will only occur on the activation of innate immune responses through workout between pattern recognition receptors (PRRs) with streptococcus derived pathogen-associated molecular patterns (PAMPs).
Moreso, cytokines and chemokines (well known are IL-1β and CXCL1 respectively) produced by macrophages and dendritic cells on exposure to Streptococcus, elicits neutrophil.
Neutrophils then produces antimicrobial proteins, reactive oxygen species (ROS) and sometimes neutrophil extracellular traps (NETs), all these for the bacterial infection control.
Answer:
Lyme disease is characterized by a <u>red rash called erythema migrans</u> at the site of infection.
Explanation:
Lyme disease is caused by the bacterium Borrelia. It is a highly communicable disease, which spreads through the bite of infected tick in humans. At the site of the tick bite, a characteristic red expanding rash can be seen on the skin. This red rash is known as erythema migrans. Other symptoms of this disease include fever, fatigue and headache.
