___ A mismatched base pair during DNA replication B. Photoreactive repair ___ A thymine dimer in a bacterial cell A C. NHEJ repair ___ A mismatched base pair that occurred after DNA replication D. Base excision repair ___ A double strand break in G1 (cell does not care about precise repair) E. HR repair ___ A thymine dimer in a eukaryotic cell F. SDSA repair ___ A double strand break in G1 (cell does care about precise repair)

Explanation:

●photoreactive repair - A thymine dimer in a bacterial

●SDSA -A mismatched base pair during DNA replication

●. Photoreactive repair - A thymine dimer in a eukaryotic cell

● NHEJ repair- double strand break in G1 (cell does care about precise repair)

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
