THE AMOUNT OF LIGNIN PRESENT in a cell is responsible for this. Once a plant cell stops enlarging, the primary cell wall is reinforced by a secondary cell wall. The secondary cell wall is made up majorly of lignin, which serves a structural function in plants. It provides a skeletal function and ultimately determined the shape of the cell.

One strand in a segment of a gene has the base sequence TGCTTA. What would be the complementary sequence of nucleotides found on
yarga [219]

The complementary sequence of nucleotides found on the other strand of DNA is <u>ACGAAT</u> when one strand in a segment of a gene has the base sequence TGCTTA.

<u>Explanation:</u>

Deoxyribonucleic acid is the one which carries the genetic information from the parent to the offspring.  During DNA replication one strand of DNA replicates to produce another strand.        

The DNA molecule have a anti-parallel structure and the two strands run in opposite direction. If in one strand in a segment of a gene has the base sequence TGCTTA the complementary sequence of nucleotides found on the other strand of DNA will be ACGAAT.
