Answer:

DNA do not normally cross the nuclear membrane.

Explanation:

DNA (Deoxyribonucleic acid) is present in the nucleus which contains the genetic information of an organism. Nucleus is necessary for whole the process of cell division and initiation. During cell division DNA plays a most important role carrying of genetic information of old cell to the newly synthesized cells, which only occurs during cell division.

All processes like replication and transcription needs enzymes which are normally found in the nucleus. So, for the protection of DNA keeping DNA within the nucleus and do not cross the nuclear membrane. If DNA is floating in the cytoplasm than DNA can not be transcribed its information into RNA and this process is known as transcription process (DNA into RNA).

15. Which of the processes has more than one type of RNA involved?
erastova [34]

Answer:

Translation

Explanation:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA’s genetic message and assembles the brand-new polypeptide chain. Transfer RNA, or tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.

Received information is called a transduced signal because: _________.
Annette [7]

Answer:

The correct answer is - e. many different molecules form a signaling cascade.

Explanation:

Signal transduction is the number of events that take place inside the body of a human from the external atmosphere to transmitting a chemical or physical signal through a number of molecular events of signaling cascade.

The transmission of the particular chemical or physical signal is caused a sequence of phosphorylation events inside the cell it involves specific protein receptors and different types of molecules.
