The primary source of the specificity of enzymes is ________. The primary source of the specificity of enzymes is ________. their polarity, which matches that of their specific substrate their shape, which relates to the lock-and-key model their bonded transition metal, which is specific to the target substrate their delocalized electron cloud their locations within the cell
Answer:
their shape, which relates to the lock-and-key model
Explanation:
Enzymes are biological catalysts that are proteinous in nature. Their proteinous nature implies that they are made of amino acids, which forms a three-dimensional shape that accounts for their functionality and specificity. This means that enzymes are substrate-specific because of their 3D shape.
The three-dimensional shape of an enzyme determines the kind of substrate it will bind to. Enzymes, generally, catalyze reactions by binding to a substrate at their active site. This binding follows a lock and key pattern or model. In a nutshell, the primary source of specificity of enzymes is attributed to their SHAPE, which relates to the lock-and-key model.

if two chromosome have equal length and size , and different in gene number would severity of chromosomal abnormalities in this two chromosome are equal?
Answer:
Unequal.
Explanation:
The severity of chromosomal abnormalities in these two chromosome are unequal that are equal in length and size but unequal in gene number are because the gene number are different from one another. If the size of gene increase or decrease from the normal range then it will leads to chromosomal abnormalities in the cell so the cells that has normal gene number has normal chromosome as compared to those cells where abnormal gene is present so the chromosomes are abnormal.

What are evolutionary relationships?
Systematics, taxonomy, phylogenetics, and evolution are the four approaches used to investigate evolutionary connections. The branch of science known as systematics is concerned with classifying species and figuring out their relationships. It has two primary branches that may be separated:
Organisms are classified, given names, and grouped in taxonomy. A population, species, genus, or higher-level grouping like a family, order, class, phylum, kingdom, or domain can all be considered as a group or taxon. The word taxon is pluralized as taxa. The determination of evolutionary links or patterns of descent of species is via the study of phylogenetics.
The species of living things that exist now are all descendants of earlier ones. This is the result of evolution or merely time-related change. Branching evolutionary trees can be used to illustrate the evolutionary links between ancestors and their offspring. An evolutionary tree shows which ancestors gave rise to which descendants, much like your family tree does.
Therefore the correct option is B.

Explain how the discoveries by Rosalind Franklin helped Watson and Crick build an accurate model of DNA.How can DNA be used to help solve a crime?
Answer:
Rosalind Franklin had taken the first picture showing the structure of DNA, called the double helix. This helped confirm what Watson and Crick had thought, thus leading them to make the first accurate model. DNA can be used to solve a crime because it can prove a certain person did something. EX: finding hair and who it belongs to/ finding finger prints and who they belong to.

What is the genetic make-up of an organism?
Answer:
Explanation:
In a broad sense,genetic makeup of an organism can be regarded as the
"genotype" . It gives description about
complete set of genes an organism.
If we narrow it, it can be reffered to as "alleles" , this is is variant forms of a gene which is been carried by an organism. For instance, Humans can be regarded as diploid organisms, i.e there are two alleles at their each genetic position along with one allele which is been inherited from each parent. genotype of a specific gene is been represented by "Each pair of alleles". Instance of this is of "sweet pea plants" the gene responsible for flowering color posses two alleles, One of the alleles is responsible for coding purple flowers, symbolized with
uppercase letter F, the other allele is responsible for coding of white flowers
symbolized with Lowercase letter" f "
There are three possible genotypes which could be featured for Different population of a sweet pea, which are
✓FF
✓Ff
✓ ff.
Genotype of each plant have some contribution to the phenotype, by saying this, we mean outward appearance of its flowers.

4. A woman with defective tooth enamel (autosomal recessive) and normal color vision, (X-linked) who had a color blind father with normal tooth enamel and a mother with normal vision and defective tooth enamel, marries a color blind first cousin with normal tooth enamel who had a father with defective tooth enamel. What is the probability of their having a child with normal tooth enamel and color blindness
Answer:
The probability of their having a child with normal tooth enamel and color blindness is 3/8 or 0.375
Explanation:
Let the alleles for normal and defective tooth enamel be T and t respectively.
Color blindness is on the X-Chromosome. Let the allele normal vision and colour blindness be Xn and Xc respectively.
The woman had a colour blind father (XcY) and a normal vision mother, so her allelic pair for vision will be XnXc.
Her father had normal tooth enamel while her mother had a defective tooth enamel, therefore, she will have the allelic pair, Tt.
Her genotype for vision and tooth enamel will be XnXcTt.
Her husband who is color blind with normal tooth enamel had a father with defective tooth enamel, tt. Therefore, her husband's genotype for vision and tooth enamel will be XcYTt.
From the dihybrid cross of XnXcTt and XcYTt, the following offspring are obtained:
XnXcTT, XnXcTt, XnYTT, XnYTt
XnXcTt, XnXctt, XnYTt, XnYtt
XcXcTT, XcXcTt, XcYTT, XcYTt
XcXcTt, XcXctt, XcYTt, XcYtt
From the results of the cross, a child with normal tooth enamel and color blindness will have the following genotypes: XcXcTT, XcXcTt, XcYTT, XcYTt, XcXcTt, XcYTt.
Probability of their having a child with normal tooth enamel and color blindness = 6/16 = 3/8 or 0.375
