When prokaryotic bacterial cells undergo cell division, the single circular chromosome replicates to form a second chromosome. T

his new chromosome, like the original, attaches to the plasma membrane. Next, the plasma membrane pinches inward, and a cell wall forms across the middle of the cell to separate the two chromosomes and form two daughter cells. How does cell division in bacteria differ from mitosis in eukaryotes?

Which two codons in the mRNA represent the amino acid phenylalanine
Trava [24]

Answer:

UUU and UUC

Explanation:

Information that encodes certain functional products called PROTEIN are present in the DNA molecule. However, the information needs to be expressed via the processes of transcription and translation. Transcription is the synthesis of a mRNA using a DNA template.

The mRNA then undergoes translation, where it is read in a group of three nucleotides called CODON. Each CODON specifies a particular amino acid. Due to the degenerate nature of the genetic code, more than one codon can specify one amino acid.

Hence, in the case of phenylalanine amino acid, codons UUU and UUC both specify it. This means that whenever UUU and UUC are read during translation, a phenylalanine is added to the peptide chain.
