Describe the most common molecular mechanism for recessively inherited human genetic diseases such as cystic fibrosis.

Biology
1 answer:
Marta_Voda [28]3 years ago
6 0

Answer:

Explanation:

cystic fibrosis is an autosomal recessive disorder. When the child receives the defective gene from both of his parents, he suffers from cystic fibrosis. Because his parents are carriers. In recessive genetic disorder, the genes will be expressed when both recessive genes are present in one person. The person suffering from this disease have a lung infection and pancreatic dysfunction.  

In this cystic fibrosis, genes are located in chromosome 7. The effective gene is the CFTR gene. The CFTR gene is present in the DNA and by transcription, this forms CFTR protein. This is a channel protein and transports chloride ion.

This CFTR protein transports chloride ions and it makes a balance in the cell membrane. These genes are commonly present in the epithelial cells. Outside the epithelial mucus is present to keep the cells moist.

The epithelium gets a lack of water and chloride due to the defect. Therefore cells need CFTR proteins also. This causes lung infection and pancreatic disorder.

Answer:

D The processes of transcription and translation, including the genetic code, are the same in the beetle as in nearly all other organisms.

Explanation:

Transcription is the cellular process where a specific DNA fragment called 'gene' is used as a template to create a complementary RNA molecule, usually a messenger RNA (mRNA). Subsequently, this mRNA is then used to synthesize a polypeptide chain (i.e., a protein) in the ribosomes. In eukaryotic organisms such as, in this case, beetles, both transcription and translation are essentially the same processes, and the genetic code used in the protein synthesis is also the same. The difference between beetles is the variation among DNA nucleotide sequences (genomes) which are used as templates to synthesize mRNAs, thereby their final products (proteins) are also different.

When an insect touches the bristles on the lobes of a Venus fly trap, the lobes close quickly, engulfing the insect. The movemen
sergiy2304 [10]

Answer:

The correct answer would be predation.

Predation is one of the types of ecological interactions which take place in an ecosystem.

In this interaction, one organism kills or hunts another organism to feed upon it.

The organism which kills or hunts is termed as predator, for example, Venus flytrap is a predator.

The organism which gets hunted or killed is termed as prey, for example, the insect is prey in this case.

Which of these processes as a cooling affect on earth? (APEX)
scoundrel [369]

Answer:

The answer is A. Evaporation of water due to warmer temperature causes low thick clouds.

Explanation:

Evaporation is the process in which liquid is changed into gas due to increases temperature or pressure. It is an important part of water recycling in nature. water from sea, rivers and streams evaporate and form clouds which brings water back to earth by raining. Evaporation also causes cooling effect as during evaporation heat is absorbed from the environment. On the other hand the cloud formation and rain also induce cooling by bringing down the temperature.

Answer:

Vor 416 bis 360 Millionen Jahren

Wurzeln waren eine frühe Entwicklung im Pflanzenleben und entwickelten sich an Land während der Devon-Zeit vor 416 bis 360 Millionen Jahren (Gensel et al., 2001; Raven und Edwards, 2001; Boyce, 2005; Kenrick, 2013).
