Methionine-methionine leucinelysine that a mutation in the DNA occurs so that the fourth base (counting from the 5' end) of the messenger RNA.
mRNA codons are read from 5' to 3' , and they specify the order of amino acids in a protein from N-terminus (methionine) to C-terminus. The mRNA sequence is: 5'-AUGAUCUCGUAA-5'
Ciodons which is broke the sequence into a series of three-nucleotide units. There are three-letter nature of codons that the four nucleotide found in mRNA such as A, U, G, and C all these can produce a total of 64 different combinations. The sequence of the tRNA anti-codon is 3'-UGC-5' and the tRNA will carry the amino acid which is the encoded by the codon.

Explanation:
Both diffusion and osmosis aim to equalize forces inside cells and organisms as a whole, spreading water, nutrients and necessary chemicals from areas that contain a high concentration to areas that contain a low concentration.
Answer:Light-sensitive cells in the retina at the back of our eye allow us to see. The human eye has two types: cones and rods. Rods are extremely efficient; a tiny amount of light can trigger them. They are responsible for our night vision

Answer:
<u>Oxbow lake is formed when a bend in a river is cut off to form a lake.</u>
Explanation:
- <u>OPTON A - It is formed as lakes grow larger due to erosion and begins to look like an ox. </u>
This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a <u>horse-shoe shaped lake .</u>
- <u>OPTION B - It is formed when a bend in a river is cut off to form a lake.</u>
This statement is correct , as An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.
- <u>OPTION C - It is formed when a delta grows large enough to cut off a river to form a lake. </u>
This statement is also wrong, as a<u> river delta</u> is specified by this statement.
- <u>OPTION D - It is formed when a dam stops the flow of a river and creates a lake.</u>
This statement is also false, since the creation of a<u> reservoir</u> is established by this statement.
<u>FORMATION OF OXBOW LAKE -</u>:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.
Hence , <u>the correct option is B.</u>
