Explain how changes in the DNA sequences will impact the expression of genes.

Biology
1 answer:
mamaluj [8]3 years ago
7 0

Ans.

DNA acts as genetic material in all living organisms that store and transmit genetic information from one to next generation. DNA sequence carries instructions for the expression of genes to make proteins, responsible for different phenotypic characters of individuals.

The DNA, first synthesizes mRNA molecule that carry information for the protein synthesis, in the form of codons and code for a specific polypeptide chain or protein.

The sequence present in DNA determines the amino acid sequence in protein encoded by the DNA. Change in DNA sequence affects gene expression as it leads to change in mRNA sequence, and thus, change in sequence of amino acid of the resulting protein.

#1

Sea breeze part

  • When the land gets warmer in day time the warm air goes up
  • To fill the free space created underneath the middle atmosphere cold air breezes from ocean surface towards land to fill up the free space .
  • This is the reason why humidity remains at peak during day time on beach sides

#2

Land breeze part

  • In night time the opposite of day time appears ,the ocean surface gets warmer.
  • The warm air rises up
  • To fill up the free space cool air from land surface goes there .
  • Humidity remains less so we feel chill during night time

Several students were having a discussion about the role of chromosomes in inheriting traits.
serious [3.7K]

Answer:

Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.  

Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.

Explanation:

Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.  - this is true. Prior to cell division, DNA molecules are organized into large structures called chromosomes. Specific regions of a DNA molecule are called genes. These dictate specific proteins which control our traits.

Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait.  - this is false - genes are segments of DNA that control specific traits by dictating the structure and functions of proteins. Chromosomes contain thousands of genes

Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different. - this is false - chromosomes are large structures, genes are the relatively small sections of DNA. Humans have 23 pairs of chromosomes, not thousands.

Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.  - this is true. In diploid organisms, like humans, have two copies of each chromosome. These chromosomes contain slightly different versions of genes, which make us unique.
