Dna And Chromosome

Question 1

How do dna differs in prokaryotic and eukaryotic cells

Answer 1

Dna molecule are circular and float freely in the cytoplasm whereas in eukaryotic the dna is protein bound as wrapped around his tones and packed into chromosomes

Question 2

What is the chromosome structure

Answer 2

It is a linear structure usually can’t be seen unless dividing then seen as sister chromatid contain dna wrapped around his tones forming his tone dna complex this is then coiled and hooped and packed into chromosomes

Question 3

What is a homologous chromosome

Answer 3

The same gene but different version of a genes one chromosome comes from each parent and form a homologous pair this number is 23 pairs and 46 chromosomes in diploid state

Question 4

What is an allel

Answer 4

Different versions of the same gene any change in a base sequence will lead to a mutation and a different version of the allele if the allele is for a protein it will lead to a primary structure which will lead to a different secondary structure and in turn a different specific tertiary structure
