How do you xxplain the main purpose of the genetic material in a cell?
the function of genetic material in a cell is to basically give instructions to the cell. the order of the sequence of the bases found in the DNA code for a certain protein to be made at the ribosomes
When a cell needs to make a certain protein it gets the directions from the nucleotides in what?
When a cell needs to make a certain protein, it gets the directions from the nucleotides in DNA, which contain the genetic code. This process begins with transcription, where a specific segment of DNA is copied into messenger RNA (mRNA). The mRNA then carries the instructions to the ribosomes, where translation occurs, and the corresponding amino acids are assembled to form the protein.
What has no ribosomes?
Ribosomes are absent in some organelles such as the nucleus, mitochondria, and plastids. In the cytoplasm, certain proteins like histones and some transcription factors are also synthesized devoid of ribosomes.
Why do bacteria have 70s ribosomes while eukaryotes have 80s ribosomes?
Bacteria have 70S ribosomes, consisting of a 50S and a 30S subunit, while eukaryotes have 80S ribosomes, made up of a 60S and a 40S subunit. The difference in size and composition is due to evolutionary divergence; bacterial ribosomes are more closely related to the ribosomal RNA of archaea than to eukaryotic ribosomes. This distinction is important for antibiotic targeting, as certain drugs can selectively inhibit bacterial ribosomes without affecting eukaryotic ribosomes.
What does the nucelolus do?
The nucleolus is a region within the cell nucleus where ribosomes are assembled. It is responsible for synthesizing and assembling ribosomal RNA and ribosomal proteins to form ribosomes, which play a critical role in protein synthesis within the cell.
When a Cell needs to make a certain protein it gets the directions from the nucleotides located in?
Messenger Rna: mRna is fed linearly into the protein manufacturing complexes known as Ribosomes.

What are hereditary traits?
Hereditary traits are characteristics or features that are passed down from parents to offspring through their genetic material. These traits can include physical characteristics, such as eye color and height, as well as predispositions to certain diseases or conditions. Hereditary traits are determined by the combination of genes inherited from both parents.
Certain block prokaryotic ribosomes but not those of eukaryotes.?
antibiotics

What courses in fertility?
Infertility is caused by hereditary factors and certain types of medication.
How does tm polarized light affect the behavior of certain materials?
Polarized light can affect the behavior of certain materials by causing them to absorb, reflect, or transmit light in specific directions. This can lead to changes in the material's optical properties, such as color or transparency.
Is nephrosis hereditary?
Nephrosis is not hereditary. ItÊ can develop as part of other diseases such as diabetes, hypertension, myolema, lupus, or asÊ a result of over use of certain drugs.
Are histones hereditary materials?
No. The only hereditary material is DNA. But histones are actually pretty interesting in their own right. They can affect what genes are available to be expressed by a cell. Some researchers think that modifications to histone proteins can be transmitted at mitosis from a mother cell to the daughter cells, thus maintaining a certain pattern of gene expression. This is part of a field called epigenetics.

What is non-coaxial strain?
Non-coaxial strain refers to a condition in which the principal directions of strain do not align with the principal directions of stress in a material. This misalignment can occur in materials undergoing complex loading conditions, leading to different deformation characteristics compared to coaxial strain, where stress and strain directions are aligned. Non-coaxial behavior is particularly significant in granular materials and certain types of soils, where the response to loading can be influenced by factors such as material structure and loading history. Understanding non-coaxial strain is crucial for accurate modeling in geotechnical engineering and material science.
