Question : Differentiate continous variation with discontinous variation.

Answer»

Solution :1. Discontinuous Variation :
Within a population there are some characteristics which show a limited form of variation .
Example : Style length in Primula, plant HEIGHT of garden pea . In discontinuous variation, the characteristics are controlled by one or two major genes which may have tow or more allelic forms . These variation are genetically determined by inheritance FACTORS. Individuals produced by this variation show DIFFERENCES WITHOUT any intermediate form between them and there is no overlapping between tow two phenotypes. The phenotypic expression is unaffected by environmental conditions. This is also called as qualitative inheritance.
2. Continuous Variation :
This variation may be due to the combining effects environmental and genetic factors . In a population most of the characteristics exhibit a complete gradation , from one extreme to the other without any break . Inheritance of phenotype is determined by the combined effects of many genes (polygenes) and environmental factors . This is also known as quantitative inheritance . Example : Human height and skin color.

Discussion
17830.

Question : Differentiate between the followings:a. Repetitive DNA and Satellite DNA b. mRNA and tRNAc. Template strand and Coding strand

Answer»

Solution : a. Repetitive sequences are stretches of DNA sequences that arerepeated many times, sometimes hundred to thousand times. When the repetitive DNA sequences are separated from bulk genomic DNA as different peaks during density gradient centrifugation, the bulk DNA forms major peak and the other small peaks are referred to assatellite DNA.
b. mRNA or messenger RNA is transcribed from DNA. It carries thegenetic information from DNA to the ribosomes for protein SYNTHESIS. tRNA or transfer RNA is the smallest RNA. It has a triplet code which is complementary to the CODON in the mRNA. It carries amino acids to the SITE of protein synthesis.
c. The strand with polarity `3. to 5. `acts as a template during DNAsynthesis. This strand is called template strand. The strand whichdoes not code for anything is called coding strand.
