These segments of DNA that contain the code for specific proteins are called genes.
Actual coding region of DNA are called exons.
Explanation:
A segment of DNA that codes for one distinct protein is called a gene. Each chromosome carries thousands of various genes. The genetic code of the DNA ever prevails protected inside the nucleus.
a gene is a stretch of DNA. Nucleotide consists of a sugar, phosphate and a base.. Genes are organized and packaged in units named “chromosomes.” Humans have 23 pairs of chromosomes.
Answer:
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.
Explanation:
Answer:
Given,
RR and Rr = Red flower
rr = white flower
Homozygous condition means that both the alleles for the gene are either recessive or dominant alleles. Heterozygous condition means that one allele is recessive and other allele is dominant.
If a homozygous red flower geranium (RR) is crossed with a homozygous white flower geranium (rr), the Punnett square would be :
R R
r Rr Rr
r Rr Rr
