Genetics Ch 1 Questions

Front 1

What were Mendel's conclusions about how traits were passed from gen. to gen?

Back 1

They follow certain predictable patterns. Controlled by discrete units, now called genes. Factors occur in pairs and members of each gene pair sep. from each other during gamete formation.

Front 2

What is the chromosome theory of inheritence and how is it related to Mendel's findings?

Back 2

it was based on parallels between mendel's model of heredity and behavior of chromosomes. thates that inherited traits are controlled by genes residing on chromosmes that are transmitted by gametes

Front 3

What are alleles? If individuals carry genes in pairs, is it possible for more than to alleels of a gene to exist.

Back 3

A gene variant is called an allele. There can be many such varients in a pop, but for a diploid org, only two such alleles can exist in any given individual.

Front 4

Contrast genes and chromosomes

Back 4

Genes are linear sequence of nucleotiedes, unsually exert influece by producing proteins through the process of transcription/translation. functional units of heredity. Assosciate sometimes with proteins to form chromosomes.

Front 5

How is genetic informatin encoded in a DNA molecule?

Back 5

encoded by the sequence of bases. This sequence is transcribed into RNA products, which are then translated into proteins

Front 6

Describe the central dogma of molecular genetics and how it serves as the basis of modern genetics

Back 6

Cent. dogma refers to relationships among DNA, RNA, and proteins. Must understand transcription and translation to understand these relationships.

Front 7

How many different proteins, each with a unique amino acid sequence, are possible in a protein that is five amino acids long?

Back 7

If a protein chain is five amino acids long at each position, there can be twenty amino acids, therefore, there would be 20^5 diff. possible combos
