a transmembrane segment of a membrane protein is all made up of alpha helix and contains 22 amino acids. what is the thickness o

f the membrane? if the transmembrane segment was made up of beta strand then how many amino acids in that beta strand will be needed to travel through the thickness of the membrane?

Nine amino acids are needed to travel through the thickness of the membrane.

Alpha-axial helix's distance between amino acids is 1.5. A

The number of gaps between the 22 amino acids in the helix is equal to (22-1) = 21.

Therefore, the helix's length is (21 X 1.5) = 31.5.

One alpha helix is sufficient to span the membrane's breadth, hence the formula is: span of the helix = thickness of the membrane = 31.5 A

The thickness of the membrane is determined by the formula above to be 31.5 AA.

In the beta-strand, there is 3.5 AA between each amino acid.

Therefore, (31.5/3.5) = 9 amino acids are needed.

What is cell biology​
Anna [14]

Answer:

Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function and behavior of cells. Cell biology encompasses both prokaryotic and eukaryotic cells and can be divided into many sub-topics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. The study of cells is performed using several techniques such as cell culture, various types of microscopy, and cell fractionation. These have allowed for and are currently being used for discoveries and research pertaining to how cells function, ultimately giving insight into understanding larger organisms. Knowing the components of cells and how cells work is fundamental to all biological sciences while also being essential for research in biomedical fields such as cancer, and other diseases. Research in cell biology is interconnected to other fields such as genetics, molecular genetics, biochemistry, molecular biology, medical microbiology, immunology, and cytochemistry.

:) please help!!! Briefly describe the traits seen in each genotype:
kolezko [41]
<h2>Answer 1 with Explanation</h2>

Homozygous dominant- It can be an organism if it carries two copies of the same dominant allele as homozygous which clearly means that the organism has a pair of models that is the corresponding allele for a gene. This gene originally belongs to a particular gene that has same alleles on both homologous chromosomes. It is assigned to by capital (XX) in the subjective terminology.

<h2>Answer 2 with Explanation</h2>

Heterozygous dominant is an organism that carries two different alleles of a gene. Though this is originally is referred to as (Tt). Heterozygous means that an organism has two different varieties of the gene within the system of dominant, the protein each makes is slightly different from one another and the organism has both tall and short versions within the dominant.

<h2>Answer 3 with Explanation</h2>

Homozygous recessive is described as an organism that carries two copies of the same recessive allele in the living organisms while they are in process of growth. A recessive gene is one that has to be homozygous to have an effect on the plant's or animal's traits that is naturally in process. This process of homozygous is is referred to by the lower case (xx).

What is happening to the amount of carbon in the living things in a biodome
Rzqust [24]

Answer:

Carbon dioxide in the biodome decreased because decomposers decreased which means there was a decrease in cellular respiration overall. How do they figure it out? They get evidence from the sim and from video of an experiment to determine which organisms do cellular respiration.

Explanation:

Hope this helped you :D
