Answer #1

I believe the correct answers to be as follows:

1) Splicing in eukaryotes removes the unnecessary introns from the sequence so the portions of DNA Sequence that will be removed are:

Intron #1 and Intron #2

2) Several proteins can be created by alternate splicing as there are several ways by which the DNA strand can be cut to remove introns such as:

Remove intron 1: Resultand DNA: ExonA-ExonB-Intron2-ExonC

Remove intron 2: Resultand DNA: ExonA-Intron1-ExonB-ExonC

Remove intron 1 and 2: Resultand DNA: ExonA-ExonB-ExonC

As seen above multiple combinations of mRNAs can be made using a single strand of pre mRNA to make different mature mRNA and different proteins respectively.

    The human genome contains about 20,000 genes, but the human body can generate over 100,000 different proteins. How is it possible that humans have so few genes but can generate so many proteins? A.

    Genes in eukaryotes are often organized into exons and intrans, which require splicing to produce an mRNA that can be translated. The gene organization is the order of the DNA segments that comprise the gene starting with the promoter, the first exon, the first intron, the second exon, and so on. The interspersed intrans can make gene identification difficult in eukaryotesparticularly in higher eukaryotes with many introns and alternative spliced mRNAs. Prediction of many genes and their organization has been...

    Hemoglobin is a protein that is found in red blood cells. It binds to oxygen in the lungs and it carries it to tissues and cells throughout the body. Hemoglobin is made of four polypeptide chains, two called “alpha-globins” (a) and two “beta-globins" (B). The B-globin polypeptide is produced in the cells based on the sequence of the HBB gene. The structure of the HBB gene that codes for beta-globin is represented below. The primary transcript is 1606 nucleotides long....
