Answer: They help control what enters and leaves the cell.
Explanation: carbohydrates also help the immune system identify if the cell is foreign or not.
This cell must be undergoing
meiosis because homologous chromosomes are associated with each other at the
metaphase plate which this does not occur in mitosis. During mitosis, a eukaryotic cell
undergoes a carefully coordinated nuclear division that results in the
formation of two genetically identical daughter cells.
Answer: d). UAG
Explanation: During translation, DNA sequence is first of all copied into an mRNA in a process known as transcription. This is the first step in protein synthesis. The mRNA is used as a template in protein synthesis. The genetic information encoded in an mRNA are in form of codons. A Codon is a three nucleotide sequence that codes for a specific amino acid. These codons are recognized by anticodons in a tRNA molecule. An anticodon is a three-base sequence on the tRNA through which tRNA base pair with mRNA.
From the DNA sequence above, 3'TAG will first be transcribed into an mRNA sequence AUC, then the anticodon on the tRNA will be UAG. The mRNA codon-tRNA anticodon base pairing follows the Watson and Crick base pairing in which Adenine pairs with Uracil and Cytosine pairs with Guanine.
Answer:
The correct answer would be the loss of its function.
Being protein in nature, the function of insulin depends on the amino acid sequence of the polypeptide chains.
Change in the amino acid sequence may result in a change of shape or structure of the protein.
Consequently, it would not be able to interact with cell surface receptors.
Thus, it would lose its function.
