What Determines The Traits Of An Organism Quizlet?


The order of the Nitrogen Bases determines the traits that an organism will possess (have). The order of the Nitrogen Bases determines the gender of an organism.

What are the following traits of an organism?

The observable traits expressed by an organism are referred to as its phenotype. An organism’s underlying genetic makeup, consisting of both physically visible and non-expressed alleles, is called its genotype.

Are alleles DNA?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. … Alleles can also refer to minor DNA sequence variations between alleles that do not necessarily influence the gene’s phenotype.

Is the observation set of characteristics of an organism?

Phenotype, all the observable characteristics of an organism that result from the interaction of its genotype (total genetic inheritance) with the environment. Examples of observable characteristics include behaviour, biochemical properties, colour, shape, and size.

Which statement best describes the relationship between cells DNA and proteins?

(1) Cells contain DNA that controls the production of proteins. (2) DNA is composed of proteins that carry coded information for how cells function. (3) Proteins are used to produce cells that link amino acids together into DNA.

What is the main function of tRNA?

transfer RNA / tRNA

Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein. tRNAs function at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an mRNA molecule.

Why is DNA so important Quizizz?

Why is DNA important? It is very small and very complicated. It’s in everything. It serves as the blueprint for traits of all living things.

How do proteins determine the traits of an organism?

The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are. But those proteins owe their existence to the DNA (deoxyribonucleic acid), so that is where we must look for the answer.

What statement best describes a human chromosome?

Which statement best describes a human chromosome? It contains genes that may code for the production of enzymes. The diagram below represents a structure found in most cells.

Which sequence best represents the relationship between DNA and traits?

Answer Expert Verified The sequence best representing the relationship between DNA and the traits of an organism is: DNA base sequence, amino acid sequence, protein shape, protein function, trait.

What does DNA stand for *?

Answer: Deoxyribonucleic acid – a large molecule of nucleic acid found in the nuclei, usually in the chromosomes, of living cells. DNA controls such functions as the production of protein molecules in the cell, and carries the template for reproduction of all the inherited characteristics of its particular species.

What is the function of DNA?

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.


What is the primary function of DNA quizzes?

DNA transports genetic information through its chemical structure and molecular behavior.

What is the main function of tRNA is relation to protein synthesis?

The overall role of tRNA in protein synthesis is to decode a specific codon of mRNA, using its anticodon, in order to transfer a specific amino acid to the end of a chain in the ribosome. Many tRNAs together build upon the amino acid chain, eventually creating a protein for the original mRNA strand.

What are the two main parts of tRNA?

​Transfer RNA (tRNA)

Each tRNA molecule has two important areas: a trinucleotide region called the anticodon and a region for attaching a specific amino acid.

What is the main function of tRNA in protein synthesis?

The purpose of transfer RNA, or tRNA, is to bring amino acids to the ribosome for protein production. To make sure that the amino acids are added to the protein in a specific order, the tRNA reads the codons from the messenger RNA or mRNA.

What is the relationship between DNA and proteins Quizizz?

DNA translates proteins into amino acids. DNA determines the amino acid sequence of each protein. DNA determines the ribosomal RNA sequence that becomes part of the protein structure.

Which best describes the difference between DNA and RNA quizlet?

Which best describes the difference between DNA and RNA? DNA contains deoxyribose sugar and RNA contains ribose sugar. … a phosphate group, a sugar molecule, and a nitrogen base.

What is the relationship between DNA and protein in a cell quizlet?

what is the relationship between DNA and proteins? a DNA molecule that contains the information to code for one specific protein. The sequence of bases in the DNA molecule determines the sequence of amino acids in a protein.

What distinguishes one organism from another?

DNA is found in nearly all living cells. … Although each organism’s DNA is unique, all DNA is composed of the same nitrogen-based molecules. So how does DNA differ from organism to organism? It is simply the order in which these smaller molecules are arranged that differs among individuals.

Can ones genotype change?

Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.

What term describes both alleles being expressed within an offspring?

Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. … In codominance, however, neither allele is recessive and the phenotypes of both alleles are expressed.

What is the shape of DNA called?

The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a “double helix,” in the journal Nature.
