Answer:
Their Cell walls
Explanation:
Bacteria has a cell made up of peptidoglycan
Archaebacteria has a cell wall made of various compounds)
Their rRNA is different, so different taht tehy are placed on different part of the evolutionary tree.
I think the answer is C because at the first the DNA shows the copies of itself when it replicate n then it transcripts n transfer the coded message for protein synthesis from DNA onto mRNA n then it translates From the cytoplasm wher the RNA enters when it translate the part of protein synthesis from the time of amino acids are assembled in a particular sequence...The transcription happens from a nucleus
Answer: Homologous chromosomes are the pairs of chromosomes that having same gene sequence, equal length of arms and centromere location. Homologous chromosomes have two homolog one come from male parent and other come from female parent.
Explanation:
These chromosomes Are formed for the purpose of genetic variations. They are called homologous because when two same structured exist it form pair together
Insertion
Genetic stability maintenance requires an extremely accurate mechanism for DNA replication and mechanisms for fixing the several accidental lesions that occur continually in DNA. Spontaneous changes in DNA are temporary due to immediate correction process called DNA repair. DNA repair’s importance is very evident from the huge investment that cells form in DNA repair enzymes. In 1000 accidental base changes in DNA , fewer than one results in a permanent mutation due to the efficient elimination by the DNA repair.<span> </span>
