D)crossing over of homologous chromosomes during meiosis.
4, 5 I think I’m not too sure
A DNA sequence that is 15 nucleotides long would normally give rise to a polypeptide sequence that would be 5 amino acids long. This is assuming that all the nucleotides in the DNA sequences are strictly coded to form only sense codons and not a single nonsense codon, also called termination codon
A sense codon is a set of three nucleotides also called a triplet, that codes for a particular amino acid. A DNA sequence of 15 nucleotides has 5 codons.
A nonsense or termination codon is one that does not code for any amino acid. There are three nonsense codons found on mRNA, and these are UAA, UAG and UGA. So if the DNA sequence has one of these, then the amino acids in the polypeptide chain will be 4 in number
Explanation:
Consumers must consume, or eat, other organisms to get matter and energy to live and grow. Consumers have to eat other consumers or plants to get food. Humans are consumers. We consume many kinds of plants and other organisms.
Answer:
Genotype: is the group or collection of genes responsible for the genetic traits of an organism.
I hope this helps :)
