Choice B is the correct answer, and if not B then D!
Answer:
The cells will contain either maternal or paternal chromosomal combination
Explanation:
If no crossing over occurs during Meiosis 1 then it greatly reduces the chances of better variations among the species. The resulting cells will contain the whole paternal or maternal genome of the parents that is result of less variant genetic combinations.

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.
