_____ 1. Which of the following is not a characteristic of a capillary?
- a. Fenestrated capillaries have pores that allow for relatively large materials to slip out of the capillary.
- b. Sinusoid capillaries are the main type of capillary around the brain.
- c. Capillaries often are arranged in a capillary bed that is supplied by an arteriole.
- d. The capillary wall consists of an endothelium and basement membrane only—there is no subendothelial layer.

Introduction:
Capillary is very small and narrow tubules whose wall is made up of only endothelium, which consist a single layer of epithelial cells. This helps in the easy movement of fluid through them. The movement of the interstitial fluid from the blood to the tissues is due to the high blood pressure at the arterial end. The high osmotic pressures at the venous end of the capillaries enable the movement of fluid into the blood.
Answer to Problem 1DYKB
Correct answer:
Sinusoid capillaries are the main type of capillary around the brain is not a characteristic of capillary.
Therefore, option (b) is correct.
Explanation of Solution
Reasons for the correct statements:
Option (b) is given as “Sinusoid capillaries are the main type of capillary around the brain”. Sinusoid capillaries does not found near the brain. The sinusoid capillaries found in the red bone marrow, liver, spleen and some endocrine gland. Hence, sinusoid capillary found near the brain is not a correct characteristic of a capillary.
Hence, option (b) is correct.
Reasons for the incorrect statements:
Option (a), is given as “Fenestrated capillaries have pores that allow for relatively large materials to slip out of the capillary”.
Fenestrated capillaries are permeable and are used to filter, release and absorbed large material or proteins. Hence, is incorrect.
Option (c), is given as “Capillaries often are arranged in a capillary bed that is supplied by an arteriole”.
Capillaries form a capillary bed which is a network of capillaries between an artery and a vein and is present in every region of the body. Hence, it is incorrect.
Option (d), is given as “The capillaries wall consists of an endothelium and basement membrane only-there is no subendothelial layer”.
Capillary is very small and narrow tubules whose wall are made up of only endothelium and basement membrane, which consist a single layer of epithelial cells. Hence, it is incorrect.
Hence, options (a), (c), and (d) are incorrect.
Sinusoid capillaries are found in the red bone marrow, liver, spleen, and some endocrine gland, but they do not found near the brain.

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.
