What chemical links the worlds of DNA and proteins?
The chemical link between DNA and proteins is messenger RNA (mRNA). mRNA carries the genetic information from DNA to the ribosomes, where proteins are synthesized by a process called translation. This enables the interaction between the genetic code in DNA and the amino acid sequence in proteins.
Is a karyotype a type of gene?
No. A karyotype is an arrangement of the 22 pairs of homologous chromosomes and the 2 sex chromosomes according to their size and shape. The chromosomes are photographed during metaphase of mitosis and then arranged by a trained technologist. Karyotypes are determined in order to check for chromosomal abnormalities. Refer to the related links to see examples of a karyotype for a female and one for a male.
What is one reason that some tissues become stiffer as they age?
when glucose is haphazardly added to proteins inside and outside cells, forming irreversible cross-links between adjacent protein molecules. The more cross-links the stiffer the tissues get with the lack of elasticity.
Briefly state what chromosomes contain and what they determine in organisms?
Chromosomes contain genetic material, specifically DNA, that carries the instructions for building and maintaining an organism. They determine traits such as physical characteristics, behavior, and susceptibility to diseases.
How does eye color pass to the young?
It is because of an inherited phenotype, a phenotype is the outward expression of genes. the source of the inherited phenotype is dependent upon whether mother or fathers genotype is consisting of dominant or recessive allele i.e a dominant allele if pair with a recessive will be the one inherited.

What percent of genes are found common between chimps and humans?
The common quote is 98.5% genetic relatedness between humans and chimps. This is based on the shear number of similar genes. However, this number does not take into account gene duplication and the specific proteins produced by these similar genes. If these are accounted for, the number is more like 94%. Despite this, chimps are still our closest living relatives. See the links below for the more accurate figure.
How many chromosomes does a pigeon have?
Okay, so a pigeon has 80 chromosomes when its cells are in the diploid stage. In the haploid stage the cells have 40 chromosomes.

Why hair curled?
Hair is curly or straight, depending upon the number of disulfide bonds between hair proteins found in the hair shaft. The greater the number of links, the curlier the hair, and the fewer the number of links, the straighter the hair.
Which group forms covalent cross links within or between protein molecules?
Disulfide bonds form covalent cross-links within or between protein molecules. These bonds are formed between two cysteine residues by oxidation of their sulfhydryl groups. Disulfide bonds provide stability and structural integrity to proteins.
Do All eukaryotic karyotypes contain 46 chromosomes?
No. Different species have different numbers of chromosomes. For example, chimpanzees have 48 chromosomes, domestic cats have 38 chromosomes, and domestic dogs have 78 chromosomes. Click on the related links to see a Wiki article listing chromosome number for many different species and kinds of organisms.
Functional group links amino acids together to form proteins?
Peptide bonds.
What is the structure inside the cell that links amino acids to perform proteins?
Endoplasmic reticulum
What links together to make proteins?
They are the amino acids. Peptide bonds hold them together
What is one reason that some tissues become stiffer as they age?
when glucose is haphazardly added to proteins inside and outside cells, forming irreversible cross-links between adjacent protein molecules. The more cross-links the stiffer the tissues get with the lack of elasticity.
What are the two base color genes for a horse?
Red (AKA chestnut) and Black. In the related links you will find a page that can tell you a ton about the red and black genes, as well as how they work with other genes. *Note: it says Morgan horses, but it goes for all breeds*
