Introduction:
Pregnancy happens when a sperm fertilizes an egg after it is released during ovulation. The fertilized egg then heads down to the womb, where it is placed. A conception ends in successful implantation. A maximum pregnancy lasts on average 40 weeks.

Answer to Problem 29A
Correct answer:
The correct answer is option (A) The amniotic sac has torn.
Explanation of Solution
Explanation/justification for the correct answer:
Option (A) The amniotic sac has torn. The fluid-filled membranous sac called an amniotic sac that envelope the infant. Normally, the membranes can break down at the onset or during labor — also known as water breaks. When the water breaks before labor begins, it is called prelabor rupture of membranes. So, this is the correct option.
Explanation for incorrect answer:
Option (B) There is a lot of pressure on her bladder. If a pregnant woman says that her water has broken that means her amniotic sac has torn. So, this is an incorrect answer
Option (C) The yolk sac has torn. Water broke means the amniotic sac is torn not the yolk sac. So this is an incorrect option.
Option (D) The placenta is leaking. When the amniotic sac is torn then it means that the pregnant lady’s lady water is broken. So, this is an incorrect option.

- What is this?arrow_forwardMolecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA?

- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB.
