Question

question 10

1. what is the importance of the sequence of bases in a dna molecule?

the sequence codes for proteins which allows for the expression of traits
the sequence determines the shape of the dna molecule
the sequence gives the molecule structure and support
the sequence of bases is simply random and is of no importance

Explanation:

DNA is the genetic material. The sequence of bases (A, T, C, G) in DNA is transcribed into mRNA (messenger RNA) through transcription. Then, mRNA is translated into proteins in ribosomes. Proteins are responsible for various functions in the cell and ultimately determine the traits of an organism. The shape of DNA (double - helix) is mainly due to hydrogen bonding between base pairs (A - T and G - C) and the sugar - phosphate backbone. The sugar - phosphate backbone gives the molecule structure and support. The sequence of bases is not random as it carries genetic information.

Answer:

The sequence codes for proteins which allows for the expression of traits.
