Answer:

b: many genes code for RNAs that function directly in the cell

Explanation:

<em>The central dogma</em> theory describes the basic framework for gene expression in living organisms. Genetic information from DNA is encoded or transcribed as RNA which then becomes translated as proteins.

The processes that take place for gene to be successfully expressed are;

  • Replication
  • Transcription
  • Translation

<em>Replication</em> is a process whereby DNA makes a copy of itself to be distributed in daughter cells during cell division.

<em>Transcription</em> is the process whereby genetic information in DNA is encoded as RNAs. The RNAs are short-lived as they are quickly utilized in protein synthesis or <em>translation </em>process.

Hence, the RNAs do not function directly in the cells but mere intermediaries in the synthesis of proteins.

<em>The correct option is b.</em>

The events listed below are all necessary for homologous recombination to occur properly:
vladimir2022 [97]

Answer:

D) D, B, C, E, A, F

Explanation:

Homologous recombination (HR) is a DNA repair pathway that consists of the exchange between two identical (or very similar) DNA regions. The steps of HR are: 1-Strand exchange, which refers to the pairing between broken DNA regions; 2-Strand invasion in order to provide a DNA crossover (Holliday junction); 3- Branch migration, capable of extending the heteroduplex regions far away from DNA crossover, 4-Resolution, where Holliday junction is resolved by cleavage of the junctions; 5- In the last step, a DNA ligase enables the joining of DNA strands.
