Nucleolus- the nucleolus synthesizes ribosomal RNA (rRNA). Afterwards, these are put together with the proteins produced in the cytoplasm to create ribosomal units. 3. Nuclear Envelope-
1. How does DNA encode information? DNA is a double-stranded helix composed of a phosphate backbone and deoxyribose, and encodes information by the sequence of its nucleotide bases, which are composed of adenine, thiamine, guanine and cytosine. DNA undergoes transcription, which produces single-stranded mRNA, which uses uracil in place of thiamine. Next step is translation, in which the RNA becomes a protein, which then can act as structural units or enzymes.

1a. Review: Describe three main differences between RNA and DNA. The three main differences between RNA and DNA are as follows: RNA has the sugar ribose instead of deoxyribose, which DNA has, RNA is single-stranded while DNA is double-stranded, and RNA uses uracil instead of thymine. 1b.
The sugar in DNA is specifically called Deoxyribose which is abbreviated to deoxyribose in DNA’s name. The acid part of DNA’s name is just showing that the phosphate groups are very acidic, so acidic
1) How does RNA differ from DNA? RNA is different from DNA in many ways. Firstly, DNA is double stranded whereas RNA is only a single strand. The sugar present in RNA is ribose whereas it is deoxyribose (one more OH) in DNA. Also, Bases in RNA are A, U, C, G (adenine, uracil, cytosine, guanine) whereas bases in DNA are A, T, C, and G (adenine, thymine, cytosine, guanine).
Deoxyribonucleic acid (DNA) is a molecule that contains the essential genetic instructions/codes that are used in the development, functioning and reproduction of all living organisms. DNA is a nucleic acid, which, alongside proteins and carbohydrates forms the three major macromolecules that are essential for all forms of life. DNA consists of two biopolymer strands, which coil together to form a ‘double helical structure’. These two strands are known as polynucleotides as they are made up of several smaller nucleotide units. DNA consists of a linear polymer consisting of three types of molecule: an organic ‘aromatic flat base’ connected to a sugar called ‘ribose’, with an inorganic ‘phosphate linker’.
Deoxyribonucleic acid (DNA) is a molecule found in all forms of life that is passed down from parents to offspring. What makes each DNA unique is the chemical makeup of the molecule sometimes referred to as the “blueprint of life.” (BIO). DNA is made up of nucleotides consisting of a sugar, a phosphate and a base pair. About six million nucleotide base pairs make up DNA in each cell.
Lesly Rodriguez Biology January 23, 2018 DNA is a long skinny molecule made up of nucleotides; the nucleotides consists of adenine, thymine, cytosine, and guanine. DNA also carries genetic information in cells and some viruses which forms two long lines of nucleotides twisted like a zipper known as the double helix. DNA can be extracted and kept in a database from having samples such as hair, saliva, fingertips, etc; the purpose of keeping it in a database is in order to secure vital information of an individual’s privacy and use it for an important event. The city of Chicago should make it mandatory for individuals and newborn babies to submit their DNA into a database. I foresee this due to solving crime efficiently, knowing circumstances that are from relatives, and the scientific method cures for the circumstances.
And therefore genes are section of DNA containing information that will code for production of a protein. The sequence of bases in the DNA is referred
DNA can be located in both the cell nucleus (nuclear DNA) and in
Genes are the genetic information carried by DNA in chromosomes, found within a cell’s nucleus; they are passed on through
DNA is a complex molecule containing the genetic information that makes up the chromosome. Genomes are the complete instructions for making an organism, consisting of all the genetic material in that organism’s
The newly made mRNA strand travels out of the nucleus to a ribosome where the directions can be made into a protein. A ribosome is composed of one large and one small subunit that assemble around the mRNA. The mRNA now passes through the ribosome. Now, amino acid building blocks are carried into the ribosome attached to specific transfer RNA (tRNA) molecules. The small subunit of the ribosome arranges the mRNA so that it can be read it segments of 3 nucleotides.
DNA in forensic science The majority of cells making up the human body are diploid cells carrying identical DNA, with the exception of haploid gametes and red blood cells. Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.
