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.

Many proteins are made and excreted from the cell. Using the list, put the cellular events in order. a. Vesicles containing prot
Irina-Kira [14]

Answer:

c. Proteins and lipids are made on the ER membrane and put in vesicles.

a. Vesicles containing proteins and lipids fuse with the Golgi bodies.

d. The Golgi bodies tag the molecules to signal their ultimate delivery.

b. Vesicles pinched off from the cristernae carry the molecule to its location.

Explanation:

Proteins are made by the ribosome machinery of the rough endoplasmic reticulum. The proteins made need to be packaged before they are sent outside the cell to their location. If the proteins are not packaged and tagged, then they will be degraded by different enzymes present in the cell. So, the packaging of the proteins is done by the Golgi-complex. After packaging is done and tags are added to the proteins, the proteins move to the outside of the cell in vesicles.
