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.
Answer:
2.They are specialized to do certain tasks
Answer:
B. Dominant for one trait and recessive for the other
Explanation:
using the Punnetts square for the question above, the 9 in the ration refers to a dominant for both traits such as AABB, AaBb.
while the 3: 3 refers to a dominant for a single trait and recessive for one such as AAbb, Aabb, aaBB, aaBb
and the 1 refers to recessive for both traits such as aabb.
There are so many examples for that in different areas, like alkyl silane experiment carried out in our lab recently.
