Question

what most vertebrates genes use a translation start codon and have a uniquely consered flanking sequences call a kozak sequence?.​

Answer 1

Explanation:

The Kozak consensus sequence (Kozak consensus or Kozak sequence) is a nucleic acid motif that functions as the protein translation initiation site in most eukaryotic mRNA transcripts.[1] Regarded as the optimum sequence for initiating translation in eukaryotes, the sequence is an integral aspect of protein regulation and overall cellular health as well as having implications in human disease.[1][2] It ensures that a protein is correctly translated from the genetic message, mediating ribosome assembly and translation initiation. A wrong start site can result in non-functional proteins.[3] As it has become more studied, expansions of the nucleotide sequence, bases of importance, and notable exceptions have arisen.[1][4][5] The sequence was named after the scientist who discovered it, Marilyn Kozak. Kozak discovered the sequence through a detailed analysis of DNA genomic sequences.[

Answer 2

Answer:

Vertebrate mitochondrial DNA (mtDNA)

The mtDNA genome is a small, circular molecule, about 16 ~ 18,000 base pairs in circumference in most vertebrate species. The genome comprises 13 protein-coding regions, two rRNA genes, a replication control region, and 22 tRNA genes.
