What would happen if a new cell does not contain chromosomes ( best answer with explantion will get brainliest)

Answer:
<em><u>a. the new cell will not have instructions on how to function</u></em>
Explanation:
Genetic information contained within DNA molecules regulates cell growth, replication, and cell repair. The long-chain, helical macromolecules of these deoxyribonucleic acids are formed from complex sequences of nucleotide monomers- secondary strands contain a complementary sequence joined to the leading strand by hydrogen bonding.
Chromosomes are the double-stranded DNA helixes wound around small molecules called histones. Genes or sequences of <u>DNA encode instructions for the cell, </u> in the form of proteins. This occurs via: the transcription processes, translation to become proteins, defining physical traits or phenotypes.

Discovery
In 1928 it was discovered by Frederick Griffith in an experiment generally known as transformation.
Experiment
In his experiment he considered two strains of <em>streptococus pneumonia,</em> one was R-type which was non-virulent and cause no disease in mice, other was virulent and S-type which cause disease and at last death of mice.
This experiment was comprised of four steps which are as follow:
Step 1:
First he injected living strain of S into mice, after sometime mouce died.
Step 2:
He injected living strain of R into mice, the mice alive as he did not got any disease.
Step 3:
He injected heat killed strain of S into mice and mice remain alive.
Step 4:
He mixed living R strain with heat killed S strain and then inject into mice. As a result the mice died.
Conclusion:
It was found that genetic material from heat killed S stain were transferred to living R (non-virulent) strain, as a result R become virulent and cause the death of mice.
