Answer: viral invasion.
Explanation:Cytopathic effect or cytopathogenic effect (abbreviated CPE) refers to structural changes in host cells that are caused by viral invasion. The infecting virus causes lysis of the host cell or when the cell dies without lysis due to an inability to replicate. Both of these effects occur due to CPEs.
Answer: Though the answer were not given, the complementary RNA strand is 5'UCCGAGGUC3'
Explanation: RNA is a single stranded nucleic acid produced from DNA. Four bases are usually found in DNA and they include adenine, Uracil, cytosine and guanine whereas adenine, thymine, cytosine and guanine are found in DNA. In RNA base pairing, wherever adenine is found in the DNA template strand, uracil occurs in the RNA strand, wherever thymine is found in the DNA template strand, adenine occurs in the RNA strand and anywhere cytosine occurs in the DNA template strand, guanine occurs in the RNA strand. This means that adenine pairs with uracil, cytosine pairs with guanine and thymine pairs with adenine.
<u>Answer:</u>
A mating of two people of medium height (where three genes control height): AaBbCc x AaBbCc produce <u>Seven</u> distinct phenotypes determined by the number of genes inherited.
Option: (D)
<u>Explanation:</u>
- Traits are the characters that we observe. When the parents AaBbCc and AaBbCc are crossed then AABBCC and aabbcc are two different dominant and recessive genomes seen in the offspring.
- Offspring with AABBCC will be height whereas aabbcc will be dwarf. There will be offspring with different heights depending upon the dominant and recessive gene present in them.
- Another genome produced are AABBCc/AaBBCC/AABbCC, next will have four dominant and 2 recessive, next will have 3 dominant and 3 recessive AaBbCc, next will have 2 dominant and 4 recessive, one dominant and five recessive. All together offspring produced will be 64
The answer is B, it bonds the DNA strand because it binds to the DNA strand during transcription to then separates the DNA strand afterward.
