b. homologous structures.
c. embryological.
d. analogous structures.
Answer:
This question lacks options but the sequence follows this pattern: DNA ---> RNA ----> Protein
Explanation:
DNA is the stored form of the genetic material in living cells. It contains the genetic information needed by an organism to function. However, this information needs to be decoded and expressed. The cell does this by employing two major processes: transcription and translation. Transcription is the process whereby the information in the DNA is used to synthesize a RNA molecule.
The RNA molecule is specifically called a messenger RNA (mRNA) which is formed by copying the information in the nucleotide sequence of the DNA into it using complementary base pairing. The next process after the mRNA has been synthesized is to use the mRNA as a template to direct the synthesis of amino acids, which are building blocks of proteins. The mRNA sequence is read in a group of three nucleotides called CODON. Each CODON specifies a particular amino acid.
The sequence of the mRNA is read in the ribosome (organnelles of Protein synthesis). Each CODON read means the addition of one amino acid to the polypeptide chain. The order of the amino acid sequence determines the PROTEIN that is formed.
In a nutshell, the order of sequence in the DNA is used to synthesize a mRNA. The order of sequence in the mRNA is used to synthesize an amino acid sequence. The order of amino acid sequence determines the PROTEIN. Hence, DNA does not make proteins directly but is a recipe for its production.
