Night blindness (n) is a sex-linked recessive trait. A woman who is night blind marries a man who is not night blind. What are the genotypes of both individuals?​

Answers

Answer:

Genotype of night blind woman -  XnXn

Genotype of normal man - XY

Explanation:

Given

Night blindness (n) is a sex-linked recessive trait. Let us say it is X linked recessive

In this case a man with XY genotype having a diseased X allele will be night blind while a woman will have night blindness if both the X allele are diseased  . In case if only one X allele is diseased in women then, she will be a carrier of night blindness defect

Genotype of night blind woman -  XnXn

Genotype of normal man - XY

Describe the differences and similarities between lecithin and cephalin. Match the words in the left column to the appropriate blanks in the sentences on the right.

The third group of the forms a with phosphoric acid, which forms another bond with an amino alcohol. In lecithins, the amino alcohol is ; in cephalins, the amino alcohol is usually .

Answers

Answer:

Here, we have a composition passage and we are required to fill in the with missing words. The missing words are highlighted in bold format and underlined.

Lecithins and cephalins are both glycerophospholipids; they consist of glycerol with fatty acids forming ester bonds with the first and second hydroxyl groups. The third hydroxyl group of the glycerol forms a phosphate bond with phosphoric acid, which forms another phosphate bond with an amino alcohol. In lecithins, the amino alcohol is choline; in cephalins, the amino alcohol is usually ethanolamine.

Explanation:

Lecithin is a chemical complex composed primarily of fatty acids, glycerol, phosphoric acid, and choline. It can be present in egg yolks, soybeans, sunflower seeds, and plant seed cells and is completely normal. Soybean and sunflower lecithins contain much more important fatty acids than rapeseed lecithin, making them nutritionally more useful.

Phosphatidylethanolamine, also known as cephalin, is a phosphoglyceride that, like phosphatidylcholines and lecithins, is a component of biological membranes. A glycerol residue esterified by two fatty acids and a phosphoethanolamine residue gives rise to phosphatidylethanolamines. They're made by combining CDP-ethanolamine with diglycerides and releasing a CMP molecule. Phosphatidylcholines are formed when S-adenosylmethionine methylates the amine in ethanolamines. They're mostly found in the inner layer of plasma membranes' lipid bilayers.

A scientist injects a drug called rifampicin, which inhibits RNA synthesis, into a bacterium. What is the most likely direct result of this alteration?

The bacterial DNA will stop replicating.
The bacterial DNA will replicate in an uncontrolled way.
The process of protein synthesis will stop in the bacterium.

Answers

The most likely direct result of this alteration is that the bacterial DNA will stop replicating. Thus, the correct option for this question is A.

What is Rifampicin drug used for?

The drug Rifampin is used to treat tuberculosis (TB) in many different parts of the body. It is also used by patients who have meningitis bacteria in their nose or throat who do not show symptoms of the infection to prevent the spread of the bacteria to other patients.

Rifampin specifically inhibits bacterial RNA polymerase. It is an enzyme that is responsible for DNA transcription, by forming a stable drug-enzyme complex with a binding constant of 10(-9) M at 37 C. The corresponding mammalian enzymes are not affected by rifampin.

Therefore, the most likely direct result of this alteration is that the bacterial DNA will stop replicating. Thus, the correct option for this question is A.

The primary source of the specificity of enzymes is ________. their polarity, which matches that of their specific substrate their shape, which relates to the lock-and-key model their bonded transition metal, which is specific to the target substrate their delocalized electron cloud their locations within the cell

Answers

Answer:

their shape, which relates to the lock-and-key model

Explanation:

Enzymes are biological catalysts that are proteinous in nature. Their proteinous nature implies that they are made of amino acids, which forms a three-dimensional shape that accounts for their functionality and specificity. This means that enzymes are substrate-specific because of their 3D shape.

The three-dimensional shape of an enzyme determines the kind of substrate it will bind to. Enzymes, generally, catalyze reactions by binding to a substrate at their active site. This binding follows a lock and key pattern or model. In a nutshell, the primary source of specificity of enzymes is attributed to their SHAPE, which relates to the lock-and-key model.
