Answer:
C. carrier proteins
Explanation:
The core of the cell membrane is made up of hydrophobic tails of phospholipid. It does not allow the water-soluble material to move across the membrane. Carrier proteins are the membrane proteins that serve as transporters.
The carrier proteins bind the ion or water-soluble molecules and undergo changes in shape. This transports the molecule across the membrane. Carrier proteins serve in passive facilitated diffusion and active transport. The carrier proteins involved in facilitated diffusion transport the molecules down the concentration gradient without any expenditure of energy.
Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air, but it is the Oxygen in the air which is necessary for aerobic respiration. ... ATP can provide energy for other processes such as muscle contractions.
Answer:
D) wild-type 5’-AUGCAUACAUUGGAGUGA-3’ mutant 5’-AUGCAUACAUCUGGAGUGA-3’ is the right answer
Explanation:
frame shift mutation is that mutation in which change in nucleotide sequence ( deletion or insertion) changes the encoding amino acid sequences.
wild-type 5’-AUGCAUACAUUGGAGUGA-3 encode MHTLE- protein sequence while
5’-AUGCAUACAUCUGGAGUGA-3’ encode MHTSGV.
in this option there is clear difference between the encoding amino acid sequence
.in option A and B, there are addition and deletion of amino acids because of addition of nucleotide.
First of all, the nucleotides of DNA and RNA are different: in DNA, in fact, pentose sugar is deoxyribose, while in RNA it is ribose, which has one more oxygen atom. Moreover, in DNA the nitrogen bases are adenine, cytosine, guanine and thymine while in RNA instead of thymine there is the uracil base
