Which of the following events causes recombination between linked genes to occur in organic chemistry reactions?
A
Crossing over during meiosis
B
Hydrogen bonding between DNA strands
C
Transcription of RNA from DNA
D
Formation of peptide bonds
Verified step by step guidance1
Understand the concept of linked genes: Linked genes are genes that are located close to each other on the same chromosome and tend to be inherited together.
Recognize the process of recombination: Recombination is a genetic process by which pieces of DNA are broken and recombined to produce new combinations of alleles. This process increases genetic diversity.
Identify the role of meiosis in recombination: Meiosis is a type of cell division that reduces the chromosome number by half, creating four haploid cells. It is crucial for sexual reproduction and involves two rounds of division.
Focus on crossing over: During prophase I of meiosis, homologous chromosomes pair up and exchange segments of genetic material in a process known as crossing over. This event leads to recombination between linked genes.
Differentiate from other processes: Understand that hydrogen bonding between DNA strands, transcription of RNA from DNA, and formation of peptide bonds are not directly involved in the recombination of linked genes. These processes are related to DNA structure, gene expression, and protein synthesis, respectively.
