Answer:

The Central dogma includes the replication, transcription and translation.

Explanation:

RNA polymerase; It is invloved in transcription process in which the the squence of DNA is coppied to RNA known as mRNA.

Spliceosomes; The genetic information is in non-continuous form i.e introns (non-codding sequences) are present between exons. These introns are removed by spliceosomes from pre-mRNA.

Codons; Codon is the sequence of three nucleotides on mRNA that code for specific amino acid i.e AUG for methionine.

Ribosomes; These are known as protein factory because protein synthesis take place in ribosomes.

tRNA; It brought the specific amino acids for corressponding codon on mRNA for polypeptide chain.

Which of the following occurs during<br> Prophase?<br><br> Answer: Nuclear envelope breaks down!
Mnenie [13.5K]

Answer:

During prophase, chromosomes condense and exit the nuclear envelope to align during metaphase. Anaphase follows metaphase, and is characterized by the separation of sister chromatids. Telophase is the final mitotic stage, during which the cell prepares for cytokinesis.

What is one of the biological uses of Nitrogen? PLZ HELP
Lisa [10]

Nitrogen is a fundamental element required during the growth and development of any organism.

  • Nitrogen is a fundamental chemical element required to synthesize different biomolecules such as nucleic acids (either DNA or RNA) and proteins.

  • Amino acids are the bounding blocks of proteins, whereas nucleotides are the building blocks of nucleic acids, and both contain nitrogen.

  • All organisms in their growth phase requires nitrogen in order to synthesize these biomolecules (i.e., nucleic acids and proteins).

In conclusion, Nitrogen is a fundamental element required during the growth and development of any organism.

Match the reproductive structures based on their function and the system to which they belong.
Rashid [163]

Complete question: Find the complete question in the attached file below.

Answer: From the question, the system to which the structures belong are:

Female reproductive structures include: Egg, ovary, fallopian tube, vagina.

Male reproductive structures include: Urethra, sperm, testis, Vas deferens

Explanation:

The female reproductive system is made up of structures, listed above, which functions together with the purpose of reproducing offsprings. Below is the structure matched with the correct function from the question given:

--> Egg: This functions as the sex cell or gamete

--> ovary: The site where gamete are produced

--> Fallopian tube: This functions to transport the gamete from the site of production in the reproductive system

--> Vagina: connects the internal reproductive fluids to the exterior.

The male reproductive system are also made up of structures that functions together to bring about the fertilization of the female sex cell. Below is the structure matched with the correct function from the question given:

--> Urethra: connects the internal reproductive fluids to the exterior.

--> Sperm:This functions as the sex cell or gamete

--> Testis: The site where gamete are produced

--> Vas deferens: This functions to transport the gamete from the site of production in the reproductive system.

ehidna [41]

Answer:

The yellow leaf was not exposed to the sun so it can't produce sugar.

Explanation:

The yellow region of the leaf didn't produce sugar because it wasn't exposed to sunlight. Part of the leaf was exposed to the sun, thus this leaf produced sugar, while the yellow part of the leaf did not because it was not exposed to the sunlight.

Proteins that assist in the movement of substances across membranes can be classified into two types based on how they move solu
kykrilka [37]

Proteins that assist in the movement of substances across  can be classified into two types which are:

  • Carrier proteins
  • Channel proteins

<h3>What are Proteins?</h3>

These are biological molecule which consists of amino acid sequences and are involved in metabolic activities in the body.

They are also found in cells and help in the selective movement of molecules in and out of the cell.
