Answer:

The difference between Prokaryotic cell and Eukaryotic cell are;

\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or}    & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \  membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}

Explanation:

Prokaryotic cells

The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells

Eukaryotic cells

Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell

Generally speaking, which of the following mutations would most severely affect the protein coded for by a gene?a) a base substi
Pavlova-9 [17]

Answer:

Answer is C.

Explanation:

For A and B, a base substitution affects one of the three bases that comprise a codon, the DNA/RNA unit that corresponds to a particular amino acid. If one base is substituted, one codon and therefore one amino acid will be affected. Codons have built-in redundancy, so even by changing one base, the new codon sometimes still corresponds to the same amino acid. Therefore, a base substitution at most affects one amino acid, and sometimes doesn't affect it all.

Frameshift mutations cause a lot more trouble. These occur when you have a deletion or insertion that changes the number of bases in your gene. As a result, the "frame" of the codons changes (everything shifts one way or the other by the number of bases added/removed). This affects EVERY codon downstream of the mutation, so you can imagine that such a mutation would have a bigger effect the closer to the start of the gene it occurs. This is why C is correct.
