The document outlines differences between DNA replication and gene transcription, noting that replication occurs for cell division and produces double-stranded DNA, while transcription produces single-stranded mRNA for protein translation. It also contrasts DNA and RNA, with DNA being double-stranded and containing thymine, while RNA is single-stranded and contains uracil instead. Overall, it highlights key distinctions in structure and function between these nucleic acids and their processes.

1. 1. Identify five differences between DNA replication and gene transcription.
DNA replication
gene transcription.
occurs in preparation for cell division,
Produces two two copies of DNA, double stranded
Uses DNA as template to form DNA
Catalyzed by DNA polymerase
the end result is two daughter cells.
happens in preparation for protein translation.
Produces mRNA, single stranded
Uses template DNA as a template and forms RNA
Catalyzed by RNA polymerase
End result is mRNA which is then exported out of the nucleus for translation
2. Identify four differences between DNA and RNA.
DNA
RNA
Deoxyribonucleic acid is the hereditary material in most of the organisms
Made of 2-deoxyribose sugar
Contains thymine as one of the 4 nitrogen base
It is double stranded
Ribonucleic acid transfers genetic code needed for the creation of proteins from the nucleus to
the ribosome.
Made of ribose sugar
Has Uracil as the nitrogen base instead of thymine
Single stranded
DNA replication
