Which of the following is a peptide bond?

A.C-H bond
B.N-H bond
C.C-C bond
D.C-N bond

Answers

Answer 1

Answer:

The correct answer is - D.C-N bond

Explanation:

A chemical bond is formed between the carboxyl group of an amino acid to the amino group of the other amino acid and release a water molecule. It is a dehydration synthesis reaction.

So, the peptide bond normally formed by the reaction between amino acid from C1 of one amino acid molecule and N2 of the other amino acid molecule.

So the peptide bond that formed by this reaction is involve bonding of C-N bond.

Can you please help me I am super stuck

Answers

Answer:

a.) 12 Newtons

b.) Same Direction

c.) Unbalanced

Explanation:

The system shows 2 individual forces:

A force of 5 N pulling the box LEFT

A force of 7N pushing the box LEFT

Both forces are LEFT, so they have the same direction.

Since the parallel forces both have the same direction, regardless of whether it's a push or pull or what side of the box the force acts upon, the resultant force will be the sum of the two forces in their direction:

Resultant force's magnitude is then: 5N + 7N = 12N

Resultant force's direction: unchanged = LEFT

Since the resultant force's magnitude is not 0, the system is unbalanced.

Describe the nonspecific antimicrobial effects of mucus, lysozyme, and acidic pH. For each of these substances, list where they are found in the body and how they function in fighting pathogens.

Answers

Answer: Non specific defence mechanism are the first lines of general defence that aids in preventing entry and minimising further passage of microbes and foreign materials into the body.

Explanation:

The non specific defence mechanisms protects us against any of enormous range of possible dangers using these methods:

--> defence at body surface

--> phagocytosis

--> natural antimicrobial substances

--> the inflammatory response and

--> immunological surveillance.

MUCUS is a slippery substance which covers the luminal surface of the Lungs. It provides defence at the body surfaces. Incase of any inhaled foreign material through the nose into the lungs, it's usually entrapped by the mucus. It is either coughed up or swallowed.

LYSOZYME: This is a protein with antibacterial properties present in granulocytes, tears and sweat. They are natural antimicrobial substances that destroys the cell walls of bacteria leading to its death.

ACIDIC Ph: The presence of acidic natural substances found in the stomach such as the gastric juice or hydrochloric acid, kills the majority of ingested microbes.

Answers

Answer:

A) vesicle

Explanation:

As described in this question, the endomembrane system is a system of membrane-bound organelles in eukaryotic cells that functions in the synthesis, packaging, modification, and transportation of lipids and proteins in the cell. The organelles that make up the endomembrane system includes: Secetory Veside, Lysosome, Golgi apparatus, Plasna membrane, endoplasmic reticulum etc.

According to this question, the part of the endornembrane system that provides a mechanism for transporting proteins from the rough ER, which synthesizes it to the golgi apparatus, where it is modified and packaged is VESICLES. Vesicles are membranous cellular organelles that function mainly in the transport of materials e.g proteins

Although bipedalism is unusual, humans are not the only living bipeds. For example, some flightless birds are also bipedal. Identify a living nonprimate animal that is also a biped. Then, compare its bipedalism with our bipedalism. Try to consider how it moves and some of its possible adaptations (such as limb length). Use resources in your classroom, credible online sources, or books to help you if necessary.

Answers

Explanation:

In simple terms, the term bipedalism refers to a term used to classify organisms that are equipped and use two legs or limp to walk, stand, jump or run.

One other nonprimate animal that is also a biped is the ostrich. When we compare the bipedalism of an ostrich with our (humans) bipedalism we discover that in terms of

Speed; an ostrich can move faster than an average human, reaching speeds of up to 70 km/h (43 mph).

limb length; its limb length can range from 10 to 16 feet (120 inches to 192 inches) which is far greater than the average length of an adult human's legs.

A particular triplet of bases in the coding strand of DNA is 5'-CGT-3! Which of

codon transcribed from this DNA?
AdGu 5
B. 3! - UGC-5
3 KGO15
0.3 AG 5

Answers

Answer:

The options to this question are incorrect.

The answer is 5'- CGU- 3'

Explanation:

DNA is the genetic material of living organisms that contains information on how to produce proteins needed for the normal functioning of the cell. This information is encoded in the nucleotide bases contained in the DNA molecule. The information is expressed via the process of transcription and translation.

Transcription is the process whereby DNA is used to synthesize a mRNA molecule. In this case, a particular triplet of bases in the coding strand of DNA is 5'-CGT-3. This undergoes transcription to give 3'- GCA- 5'.

This further undergoes translation with the aid of a tRNA, which carries the following anticodon component which is complementary to the mRNA codon: 5'- CGU- 3'.

Y gene R gene Precursor substrate Intermediate substrate Product and lacks color and fruit is and fruit is yellow fruit is red green from chlorophyll Mutations in the genes for both of the enzymes produce lack-of-function, recessive alleles. What would be the expected genotypic and phenotypic segregation ratios if you self-fertilize a RrYy individual

Answers

Answer:

Explanation:

From the information given:

The analysis of the hypothetical pathway gives:

                         Y gene                                  R gene

Green fruit            →         Yellow fruit               →           Red fruit.

If RrYy undergoes self-fertilization, the expected genotypic and phenotypic segregation is:

RrYy × RrYy

The progenitors to undergo the segregation are as follows:

                 RY            Ry            rY                 ry

RY             RRYY      RRYy         RrYY            RrYy

                (red)           (red)        (red)            (red)

Ry             RRYy        RRyy         RrYy           Rryy

                (red)         (green)       (red)           (green)

rY             RrYY           RrYy         rrYY            rrYy

               (red)             (red)        (yellow)      (yellow)

ry              RrYy         Rryy            rrYy             rryy

                (red)          (green)        (yellow)      (green)

Thus; the expected phenotypic ratio is:

= 9(red)  : 3(yellow) : 4(green)

The expected phenotypic ratio is:

= 1(RRYY): 2(RRYy): 2(RrYY): 4(RrYy): 1(RRyy): 2(Rryy): 1(rrYY): 2(rrYy): 1(rryy)

During DNA replication, the DNA polymerase enzyme produces a complemetary strand from each of the original strands.

What is DNA replication?

It is the process by which DNA produces a copy of itself at the time of cell division. In the process of replication, the initial step is the unzipping of the double helix structure of the DNA. This is done with the help of enzyme helicase. The unzipping creates a Y shape composition called replication fork.

Towards the replication fork, one of the strands is oriented in the 3' to 5' direction, known as the leading strand. The other strand in the 5' to 3' direction is the lagging strand, which is away from the replication fork.

The primer combines with the leading strand, and marks the intiation point of the synthesis of DNA. After this, DNA polymerase combines with the leading strand and add complementary nucleotide bases in the 5' to 3' direction.

In the lagging strand, numerous primers come and bind, later the chunks of DNA called Okazaki fragments are supplemented to the lagging strand in the 5' to 3' direction, by the enzyme DNA polymerase. This kind of replication is termed discontinuous as the Okazaki fragments are joined up later.

Thus, the correct statement is the second one, that is,  the DNA polymerase enzyme produces a complemetary strand from each of the original strands.
