One prey-predator relationship in the reef is the eel-shrimp
relationship. The eel predates on shrimps, crabs and small fishes. The eel
hides and awaits its prey in the crevices
of the coral reefs. They only emerge from the crevices in the night to hunt
shrimps and other prey.
Answer:
A protein-coding gene has an open reading frame (ORF) that make easier its identification
Explanation:
During translation, the messenger RNA (mRNA) is read by the ribosomes as triplets of nucleotides called codons in the open reading frame (ORF). An ORF can be defined as a gene fragment composed of codons which are translated into amino acids in a polypeptide chain. According to the genetic code, the information encoded by these codons will specify the sequence of amino acids in the protein, as well as the start codon and stop codons of the protein-coding genes. A start codon (AUG) is a site at which translation into protein begins, while stop codons (UAA, UAG, and UGA) mark the site at which translation ends. Moreover, non-coding RNAs (ncRNAs) don't have ORFs because they do not encode for proteins, and therefore their identification is more difficult.
Komodo dragons can reproduce both sexually and asexually depending on the environment. They can do this because of Parthenogenesis (Parthenogenesis is a natural form of asexual reproduction in which growth and development of embryos occur without fertilization. In animals, parthenogenesis means the development of an embryo from an unfertilized egg cell.)
UV light caused cancer because it damages the DNA in our cells. Changing the characteristic of a cell can cause cancer
