Bacteria caused diseases i think
Answer:
b. Highly repetitive sequences
Explanation:
As the name suggests, highly repetitive sequences are the sequence in the linear chain of DNA that are repeated many times in the whole genome. Though these sequences occur in abundance in the genome but it is interesting to note that these do not code for any protein. These sequences can be short as of 5-100 nucleotides and are repeated for thousands times in a single stretch of genome and include the satellite DNA. The longer sequences can be 150-300 nucleotides and include transposons and Alu sequences.
<h3><u>Answer;</u></h3>
<em>Common ancestry </em>
Similar DNA sequences in genes can be evidence of <u><em>common ancestry</em></u>
<h3><u>Explanation;</u></h3>
- <em><u>DNA molecules are fundamental molecules in organisms since they carry genetic information in living organisms.</u></em> DNA sequences similarity among various organisms may be used to establish evolutionary relationship among living organisms.
- <em><u>Many organisms have distinct DNA sequences, however, animals may share some specific types of genes which are similar genetically in the sequences of DNA. </u></em> Organisms or animals whose DNA sequences are similar share common evolutionary origin.
