Answer:
D. they are usually dominant or recessive.
Explanation:
alleles are pairs of genes found on a particular spot a chromosome. If one is dominant over the other it give rise to a particular trait.
Genetic counselors typically receive a bachelor's degree in biology, social science or a related field, and then go on to receive specialized training, so I would say your answer would be B.) must have a degree in biology or genetics. I hope this helps!
The answer is; 24 hours.
Scientists called the full rotation of the earth a day and divided it into 24 hours on the clock. This means from sunrise to next sunrise. They also divided the earth into latitudes that indicate time zones. When one point on earth rotates and return to the same position in space, it has lapsed 24 hours.
Answer:
The correct answer is option C. "A single tRNA specific for a particular amino acid may respond to multiple codons in an mRNA".
Explanation:
Genetic code is said to be "degenerate" because there are more codons than amino acids, which is possible because a single tRNA specific for a particular amino acid may respond to multiple codons in an mRNA. tRNA recognize the codons of the mRNA by a specific nucleotide sequence called anticodon, however the nucleotide sequence of the anticodon can recognize more than one codon sequence. This phenomenon takes place at the third position of the codon and is known as "wobble".
