Why do plants of the fields become yellowish?

aliina [53]

Answer:

Poor drainage or improper watering

Explanation:

Water issues — either too much or too little — are the leading reason behind yellow leaves. In overly wet soil, roots can't breathe. They suffocate, shut down and stop delivering the water and nutrients plants need. Underwatering, or drought, has a similar effect.

Explanation:

A. The differential induction of DNA transcription suggests the cells are destined to become different tissues.

Given the lack of RNA encoding, DNA transcription is not occurring. This may happen because the cells are destined to undergo different forms of differentiation- here, transcription would require the activation of different regions of the genetic code called transcripts.

Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
