Indicate whether the C-terminus (C) or the N-terminus (N) of each of the following proteins is expected to be located in the cyt

musickatia [10]

Answer:

The correct answer is - CNN.

Explanation:

Protein modification or folding takes place in the endoplasmic reticulum. The Endoplasmic Reticulum modifies the amino acids according to their signal sequences and tail. The following case can help in indicating the C-terminus (C) or the N-terminus (N) of each of the following proteins-

A) the C-terminus would be placed in the cytosol and the N-terminus in the endoplasmic reticulum lumen after cleaving the N-terminal signal sequence.

B) The N -terminal is the positive end of the chain and as per the rule of positive inside it allows N terminal in the cytosol

( C ) Tail-anchored proteins always have their N-terminal bulk in the cytosol.

Thus, CNN would be the correct answer from the explanation given above.

3. use the simulation to observe the first-generation offspring from the cross between flowers c and a. what is the most likely

JulsSmile [24]

To observe the first generation offspring of the cross between the flowers c and a. the most likely genotype of flower c is its color.

<h3>What is genetic probability?</h3>

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck. It can be defined by the following formula: Where P is the probability that an event will occur, A is the number of desired events, and S is the total number of possible events.

With this information, we can observe the first generation offspring of the cross between the flowers c and a. the most likely genotype of flower c is its color.

A researcher while working in vitro (outside cell) added helicase enzyme which resulted in the untwisting of the DNA helix. But

GREYUIT [131]

The answer is Topoisomerase.

Topoisomerase is an enzyme with the role to regulate the overtwisting or undertwisting of DNA helix. If DNA helix is untwisted, topoisomerases will regulate this situation and will twist DNA helix.

Nuclease is an enzyme that cleaves the sequences of nucleic acids into smaller units.
Telomerase is an enzyme that adds specific sequence to the telomere ends.

The underlying structure of DNA is very simple, consisting of only four possible building blocks. a. How is it possible for DNA

aleksklad [387]

Answer and Explanation:

a) Although the DNA is made up of only four possible building blocks, these blocks are combined from a 3 (form triplets of nitrogenous bases) giving rise to a large variety of nucleotide sequences that carry a large amount of genetic information.

b) DNA is a polymer formed by nucleotides, which we could consider as the building blocks.

Each of these nucleotides is, at the same time, formed by a carbohydrate, a nitrogenous base and a phosphate group (derived from phosphoric acid). The nitrogen base may be adenine (A), thymine (T), cytosine (C) or guanine (G).

The nitrogenous bases are located in a complementary manner between the two strands of DNA, with thymine-adenine being joined by a double bridge of hydrogen and cytosine-guanine by three hydrogen bonds.

Example of questions A and B: AAA, AAT, AAC, AAG, ATT, ACC, AGG, ATA, ACA, AGA, etc.

c) In RNA the carbohydrate that is present is ribonucleic acid while in DNA it is deoxyribonucleic acid.

In addition, in the RNA, the thymine nitrogenous base is replaced by the Uracil.
