Embryonic stem cells (ES cells or ESCs) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells. Hope I’ve helped ;)

Which is not something that occurs in translation? A codon and an anticodon pair. A peptide bond is created. A molecule of mRNA
Veseljchak [2.6K]

Answer:

A molecule of mRNA is formed.

Explanation:

Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.

The mRNA nucleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. Translation, which occurs in the ribosomes (cytoplasm), reads the codon with an anticodon using the complementary base pairing rule i.e. A-U, G-C. This means that a CODON-ANTICODON pairs.

The anticodon carries a corresponding amino acid to the polypeptide sequence. A peptide bond is formed when two amino acids joins together in a condensation reaction.

Note: A molecule of mRNA is formed during transcription
