Answer:
A protein molecule present in the RBCs, which helps in the transportation of oxygen from the lungs to the different parts of the body and brings back carbon dioxide, that is, collected from different parts of the body back to the lungs is known as hemoglobin.
The general features of hemoglobin are that it comprises four molecules of protein in the form of globulin chains. In adults, the molecules of hemoglobin comprise two beta-globulin chains and two alpha globulin chains, while in infants and fetuses, the beta chains are least found, and is substituted by two gamma chains.
Each globulin chain comprises an essential iron-containing compound porphyrin, which is termed as heme. Together both iron and heme play an essential role in circulating oxygen and carbon dioxide in the blood. This iron gives the red appearance to the blood.
Answer:
Original reading frame=> (ATG)(CGT)(CCA)(TGA)
Altered reading frame => (ATG)(CAC)(GTC)(CAT)(GAG)
Explanation: A frame shift mutation is a type of mutation in which there is addition or deletion of one or more nucleotides in a DNA sequence which results in alterations in the original reading frame of the DNA sequence. In the altered reading frame above two nucleotides were added at positions 4 and 5 thereby changing the subsequent reading frame of the DNA. Frame shift mutation can result in permanent change in DNA sequence during replication and subsequently in altered RNA sequence during transcription and altered amino acid sequence of the final gene product.
