In eukaryotes, the DNA strands are linear, and DNA polymerase can't replicate the very ends of the DNA strands! These ends are "protected" by repeated sequences called "telomeres." Either the chromosome gets shorter with each replication, or else a special enzyme-nucleic acid complex called telomerase adds new telomeres to the ends. A prokaryotic chromosome is circular and thus does not have the problem of having ended.
<span>Eukaryotic DNA is wound around histones, coiled, and supercoiled -- to replicate it, there have to be unwinding mechanisms, and mechanisms to reduce the degree of coiling. In prokaryotes, the winding problem is much less, and there aren't any histones.</span>
The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.
Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.
Answer:
Incomplete dominance
Explanation:
Incomplete dominance is the expression of phenotype of two paired alleles (i.e dominant and recessive allele) all together.
Usually when two alleles get paired, the characteristics of the dominant allele is expressed while the characteristics associated with recessive alleles are expressed only when the two recessive allele get paired.
Here in this case the characteristics of both type of allele are expressed i.e. both orange and purple strips appear in the offspring. Hence, this case shows the incomplete dominance.
Answer:
Nuclei and vacuole
Explanation:
But in animal cell vacuole are temporary exist
