Answer:
The codons that code for LEUCINE amino acid are:
1. UUA
2. UUG
3. CUU
4. CUC
5. CUA
6. CUG
Explanation:
A CODON is a group of three nucleotides in the mRNA molecule that specifies a particular amino acid. It represents a trio combination of nucleotides (A, G, C, U). There are about 64 possible codons formed from four nucleotides used in a combination of three's i.e 4³ = 64. All the codons collectively form the GENETIC CODE, which is used by all known living organisms.
However, since there are only 20 amino acids in nature and 64 possible codons, more than one codon encodes an amino acid. This means that the genetic code is DEGENERATE or REDUNDANT. Hence, in this case involving the amino acid: LEUCINE, the six (6) codons that specify it (depicted in the attached genetic code) are as follows:
- UUA
- UUG
- CUU
- CUC
- CUA
- CUG
Answer:
Agarose gel or Pores in the gel
Explanation:
This question could have multiple answers because the gel has pores in it that allow smaller fragments of DNA to move faster through the pores because they're not getting stuck in the gel. Larger fragments of DNA get stuck in the gel as they try to fit through the large pores.
So, you could either say the agarose gel itslef or you could say the pores in the agarose gel allow the molecules to move at different rates.
The blood flows through hepatic portal vein traveling to the liver, then makes it another artery which is posterior vena cava making it to the heart. It makes itself afterward to the pulmonary artery where it reaches the lungs, going back to the heart via the pulmonary vein. Eventually, it goes to the kidney through different parts such as the aortic arch, dorsal aorta and the renal artery.
The main role of the lungs is to process the gas exchange called respiration
