Exemplar Problems

Question:

Briefly describe the following:

(a) Transcription

(b) Polymorphism

(c) Translation

(d) Bioinformatics

Answer:

(a) Transcription is the process of synthesizing mRNA from a DNA template. It is the first step in gene expression and occurs in the nucleus.

(b) Polymorphism refers to the presence of multiple alleles or genetic variations within a population for a particular gene or trait.

(c) Translation is the process of synthesizing proteins from mRNA on ribosomes. It involves the conversion of the mRNA code into a sequence of amino acids.

(d) Bioinformatics is the interdisciplinary field that combines biology and computer science to analyze and interpret biological data, such as DNA sequences and protein structures, using computational tools and algorithms.
